Try an HF Net… Rack up those States and Countries FAST!

I was rolling across the 40 Meter band one night and hit a nightly net called the OMISS NET (Old Man International Sideband Society) and there was a busy back and forth between stations making a call sign and signal report in a very orderly way on 7.185 MHz LSB.  So, I tuned up (off frequency) and when they called for “check-ins” I threw my WT8WV call sign in and they called me back and the next thing I knew I racked up 14 new states in about an hour or so!  The next night I added 10 more states!  They have nets on most of the HF frequencies and can be found on their website.

OMISS 101

OMISS, or Old Man International Sideband Society, has been operating list-type awards nets on the General Amateur bands since 1981. Want to get your WAS quickly? This is a great place to get it done. Do you like to work lots of stations for unique awards? We have several challenging awards to work for, each with an attractive certificate to hang on your wall. Do you like contesting? We hold an annual QSO Party and invite the whole Amateur community.

The real cool thing is they use a free software program called NETLOGGER  (see info on Netlogger below) that is an online logging server that shows in real time who has checked into the net and available to be contacted. When it’s your turn, you call who you need and make the exchange with them.  Then as you listen someone might want to call YOU to get your state!  Slick as a whistle!  For a one time cost of $7 you can get your own OMISS Number (i.e. 10722 is assigned to me) and you log in with it each time for a speedy check-in process and it is also tied to numerous awards you can get.

Perfect CW / Morse Code Trainer

This program G4FON Koch CW Trainer has been a joy to play with and learn from.  I am wanting to increase my Morse Code speed skills and this is a perfect way to do that!  I am wanting to get back into CW but have gotten rusty from not practicing for years.  I seem to be stuck at copying  about 7 words per minute.  My goal is 20+ words per minute so I can help rack up more points at Field Day events!  The key, I have now found, is to HEAR letters at 25 words per minute… but at a longer spacing between them when received, and then begin shortening that spacing time over a period of practice sessions.

koch_display

I have it set to send the individual letters at 25 words per minute (wpm).  I am starting at the time between those letters at 10 wpm.  I started with two letters and would copy just those two for a few minutes in one minute drills.  Once I get to 90-100% copy, I add another letter!  I practice about 15 minutes each night, if I can.  I am halfway through the alphabet now and having a ball.  It is easy to download and configure… you’ll be instantly surprised at how much fun it is!

You Need Your Own QSL CARD

WT8WV QSL

I know, I know… we have QRZ and eQSL and LOTW (Logbook of the World) and Ham Radio Deluxe (HRD) and Netlogger and N1MM and… blah, blah, blah.  An old fashioned paper QSL card is still sweet to hold in your hand and to enjoy the real memory of a fun contact. Especially if it’s a DX station from a far away land toward DXCC or the last state you needed for WAS.

They aren’t as expensive as you think.  For simple black and white cards you can buy 100 cards for about $12… my color card above cost about $30 for 100 of them.   I got mine from Cheap QSL’s on the internet and they sent the proofs the same day and shipped them out the same day!  Most folks are migrating toward electronic QSL’s these days.  I predominately use Ham Radio Deluxe (HRD) Logbook for my main logging software but also upload my logbook to eQSL, QRZ and LOTW every couple days of logging, however if someone requests a paper card I will oblige.  Sooooooooo… if I do that once in a while I’ll have about 65 cents in the effort by the time I add postage.  Below is a Special Events Station I worked and got this electronic QSL a few days later…

Merle Taylor: Maven of Morse Code

Such a great story!  Click link below after reading first few paragraphs for the full story and pictures.  (by Elinor Florence)
1._Merle_doing_code_feature

When this Manitoba farm girl joined the Royal Canadian Air Force, she proved to be such a whiz at Morse Code that she was assigned to instruct the air crews. Now almost ninety-three, Merle still practices her dots and dashes every day, claiming that Morse Code keeps her mind sharp.

Merle Taylor of Lochaber, Nova Scotia, wrote to me after reading my column in The Senior Paper, a newspaper widely distributed to seniors across Canada. (If you haven’t seen a copy yet, email me for more information).

We exchanged copies of our books – I sent her my wartime novel, Bird’s Eye View; and she sent me a copy of her memoirs, Until the Cows Come Home.

When my husband and I travelled to the Maritimes recently, I was determined to meet Merle in person. We found her still living on the farm she operated with her husband Fred since 1946, about thirty kilometres south of Antigonish.

After serving lunch to us, Merle took me on a farm tour in her electric golf cart. I loved hearing her stories of life in the air force, and in the decades since then.

Programming Your New Ham Radio… the Easy Way!

ADMS_M100_U_2__89502.1447692865.220.220

downloadI recently took a deeper dive into digital ham radio and picked up a Yaesu FTM-100 mobile System Fusion rig.  VHF and UHF… 500 Channels on each band!  Holy Crap, Batman…  I’ll wear my aged, stubby, fat fingers to the nubs tryin’ to poke all that individual channel info into those 1,000 spots using those little buttons!  Plus, I have to look up all that info… somewhere… on EVERY channel I want to add to my line-up.  Ain’t no-body gotz time for dat!  (I also had to do that with my Baofeng UV-5RV2+ portable HT a couple years ago.)

What to do?  Path of least resistance!  Did a little research and found a computer program that does it all for me.  (I actually used the free CHIRP software to program my HT a couple years ago.)  RT Systems software makes the programming easy!  You simply pick out your software version based upon what radio you want to program, download the software, (Hopefully your radio came with the right interface cable to hook your radio to your computer to make the download of freq’s to your rig.), grab the repeater frequencies from some site like RFinder World Wide Repeater Directory and in 20 minutes you can load up your rig with more frequencies than you will ever use.  (While CHIRP is freeware, RT Systems and RFinder software platforms are paid versions.  I can honestly say that the software is very reasonably priced for both and you might only need to use it once in a while but it saves you HOURS of manual poking and prodding your radio buttons.)

(Click link below to see the typical instructions)

Radio Programming Software for the Yaesu FTM-100

(See the videos below…)

You can easily marry RT Systems software to RFinder software and quickly create a sort routine that grabs the EXACT frequencies you want and transfer it to your radio.  You can sort by town, state, zip code, ham bands, NOAA frequencies, etc.  

It makes short work of all of it!  You’ll spend more time convincing yourself to not pull in frequencies you will never use than the download takes!  

Once you set up your channel database you want to use for your radio, you simply hook your radio to your computer with the cable… poke a couple drop-down menus… and then the magic happens!  UPLOAD COMPLETE.  

I programmed about 75 VHF and 75 UHF Channels into my radio, start sort to finish sort to upload compete in under 20 minutes.  You might export your databases to your laptop or website to store for the future.

One thing I did that sort of brought sanity to my programming strategy and thinking was that I added the freq’s in sort of “banks” of channels so I could visually sense what channels I needed to tune to depending on my car’s location as I traveled.  For the first 10-15 channels, I loaded repeater data for the local area repeaters within about 75 miles of my home QTH.  I live just below the Mason-Dixon Line…  and yes, I consider myself a southerner but I can be in Pennsylvania within 10 minutes; in fact, I can be at the Pittsburgh International Airport in under 90 minutes!  So, since I travel a good bit for work, I can bounce to various repeaters as I drive in any direction!

In the next grouping of channels I might add just the Pittsburgh area repeaters.  In another group of channels I added the Dayton, OH repeater freq’s since my daughter and son-in-law live and work next to Wright-Patterson AFB and I also usually attend the Dayton Hamvention each year.  Another group of channels I include are the NOAA Weather Channels.  Other groupings include various regions of West Virginia since I also hunt, fish, camp and hike all over the place.

 

Morse Code: Straight Key and Others

I enjoy a niche of ham radio called Continuous Wave (CW) / Morse Code sending and receiving.  There are all sorts of hand keys out there to use.  Lots of CW Contests occur every month for all levels of CW enthusiasts… you don’t have to send fast, if you don’t want to!  It’s a very efficient system of communicating when traditional modes of messaging are out of service, too.  Some say since the advent of the telephone and then the cellphone, it is a dying art… I say it’s a BLAST to do!

Every ham ought to try a little CW every once in a while.  Find a key you like and use it periodically to stay proficient but also pick up a straight key and join the annual Straight Key Night Contest around New Years.  (It’s not really a contest; it’s more of an opportunity to pull out a straight key and try sending Morse Code the old fashioned way.

I love to scour the hamfest flea markets looking at all the old time keys available to buy for a variety of prices.  Some served in Post Offices, Telegraph Offices, military communications, in combat and in ham shacks!  My favorite straight key is a 1950’s era South African Special Forces straight key… super compact… light weight… and darned cute… that I picked up at the Dayton Hamvention in 2015!  It wasn’t cheap, but it’s unique and has a good story.  See some of the key configurations below…

Bencher Paddles and Memory Keyer UNITE!

As soon as I get my Yaesu System Fusion FTM100-DR online, I want to mate my Bencher paddles to the new MFJ-490X Menu Driven Memory Keyer that I picked up at the 2016 Dayton Hamvention last week (May 21, 2016).  I am itching to get these two toys working in some CW / More Code Contesting very soon!  5 programmable memories plus all sorts of keyer speed, weighting, side tone, hand key capability, serial number decrements, random code practice, iambic settings, etc.

(See video below!)

This is an excellent explanation of the taxonomy of a dual lever paddle (i.e. Bencher and MFJ) and how to make the adjustments that are critical for efficient CW / Morse Code sending in your ham shack.

The alphabet in Morse Code / CW sent at 20 words per minute (wpm)…

This is a good introduction video for anyone curious about Yaesu’s efforts in digital communications at the local repeater level.  It also sets aside some fears and misunderstandings about amateur radio operators making the decision to add or upgrade to digital from analog… you can do both!

2016 Dayton Hamvention Post-Mortem

Well… another Hamvention is in the books and it was the usual great time of fun and friendship.  WR8S  (Bill Shultz) and WV8TG  (Tom Graf) and I enjoyed three fun-filled days scouring the Flea Market and also inside Hara Arena for all sorts of treasures and trinkets.  Tom scored a pristine 1959 Hammerlund HQ-One Forty Five short-wave radio and several other vintage radios to restore.  (The Hammerlund was the first serious short-wave radio Tom bought and it eventually led him on the journey to get his Amateur Extra Class license!)  Bill and I invested in a couple Yaesu FTM100-DR System Fusion digital mobile radios so that we can explore the Monongalia Wireless Association’s new System Fusion repeaters here in the Morgantown, West Virginia area.  Below is a video recap of our annual trek to the Dayton Hamvention.  If you have never attended a Dayton Hamvention… GET THERE!  Enjoy!

Aluminum Soldering Demonstration at the 2016 Dayton Hamvention

I have seen this presentation several times over the years while attending the Dayton Hamvention.  Don Wilke does a great job demonstrating the process of bonding various metals at a low temperature using this special material.  I finally purchased a pack of these rods in May 2016.  As many things as I can mess up around the house and garden, I am sure it will come in handy soon.  I decided to film it for my blog and then sent the video to Don for him to use.

Complete Overview of MESH for Amateur Radio (2014) by VA3BCO

MESH communications in Ham Radio is another area where Amateur Radio pushes the edge of the envelope and  has put a tremendous amount of work into this slideshare that goes from A to Z on how to run a MESH!  (Click on his website for more!)

Originally published on Nov 6, 2014

This is a comprehensive introduction to MESH for amateur radio enthusiasts. It is particularly useful for anyone new to MESH but will also include some nuggets sure to be helpful to the experienced operator. Topics include:

1. HSMM MESH vs. traditional digital modes
2. Router review & comparison
3. Firmware selection & configuration
4. Antenna considerations
5. Application scenarios for ARES and experimentation
6. Updates on local efforts & recent software announcements

Visit VA3BCO.COM for more details.

APRS… Automatic Packet Reporting System

The thing I absolutely LOVE in this wonderful hobby of Amateur Radio is that there are so many diverse niches to explore!  Everything from building your own radio, working through satellites in orbit, transmitting your own slow or fast scan TV signals, Morse Code working over 300 countries in the world on less than a half of a watt of power, emergency response, tons of digital modes, bouncing signals off of the moon, ricocheting your signals off of an excited aurora… basically, if you have an idea on getting a signal transmitted or received to someone you can invent your own technology!

Automatic Packet Reporting System (APRS) combines ham radios, GPS and tiny computers to report your location, regardless if you are standing on a street corner, in a moving car on the highway, camping, hiking, boating, balloon tracking, airplanes or even in space!  Believe it or not, your own cellphone can serve as the computer part, software and GPS .  Check out this slideshare from  on the nuts and bolts of this fun segment of ham radio.  (Click on his name above and check out his other presentations!)

Ham Radio… Do they still DO that?

This is a great slideshare from KB6NU Dan Romanchik,who unequivocally answers, “Oh HECK yes!”  After more than 45 years of having a blast using my ham radios and talking all over the world using all sorts of cool technologies, I echo Dan’s message here.  Thank you, Dan!  If you want to find a great hobby that you will enjoy for a lifetime… drop me a note… I’ll hook ya up!

REVIEW: Yaesu Fusion FT2DR dual-band digital portable radio

ft2d_thumb

This is a solid review by Don Trynor from VA3XPR from July 2015 of the Yaesu FT2DR dual-bander HT.  (They have a very nice website!)

Our local ham radio club, Monongalia Wireless Association, recently bought 2 of the Yaesu Fusion repeaters and I am doing my own research into being able to enjoy a new type of technology. I am looking at my options and hope to find something to get my hands on at the 2016 Dayton Hamvention!  I would think that prices would be moderating downward by now as others adopt the new radio and there may be some rebates floating around or “Specials” by some of the dealers.  (Read Don’s full review here…  Review: Yaesu Fusion FT2DR dual-band digitl portable radio )

The FT2DR is a good choice for anyone looking for a full-featured dual-band portable radio that is compatible with Yaesu’s Fusion line of digital radios. While this radio has some innovations, we think that they may not justify the $550 USD price point of this unit. In addition, we feel that Yaesu could improve upon future radios like this one, especially as it relates to the overall user experience. In this day and age when a good user experience for touch screen devices is the norm, such as with smartphones and computers, we think devices like this have room for improvement. All in all, if users can live without the touch screen display and louder audio, they might want to consider a cheaper alternative in the Yaesu FT1DR, which retails for $300 USD.

Amateur Radio Licensing in the UK

Ever wonder how folks in the United Kingdom get their Amateur Radio licenses?  It’s different… but also similar to how we go about things here in the United States.  Let’s take a look at the YouTube video from Essex Ham

WinLink… What is it?

K4REF tells us from his YouTube Channel the basics of this interesting technology that we can use as Amateur Radio Operators.  It is most likely very similar to a technology we use daily… away from our radios!

 

Amateur Radio Go-Box and Go-Bags Examples

Ham Radio Operators need to be ready to roll out to a crisis quickly if it requires communication support.  Are you ready to “grab and go”?  How quickly could you have a functional ham radio station on-the-air ready to support an emergency situation?  Could you support your local authorities efforts, and for how long?  Can you personally sustain yourself with food and water for 3 days of support, without being a burden on the emergency relief efforts?  Constructing your own version of a “Ham Radio Go-Box” and a “Go-Bag” might be a great addition to your preparedness efforts.  Below are some pictures of potential Go-Boxes to stir your imagination and creativity.  You might even have some of the items laying around that could be put into the effort to BE PREPARED.

How Does a Crystal Radio Set Actually Work?

Here is an excellent YouTube video from RimstarOrg that breaks down the concept of how crystal radios actually DO their magic!  Yes, MAGIC.  Radio signals are all around us 24 hours a day.  Invisible!  You can’t really touch them.  You can’t smell them.  You can’t hear them without assistance.  We don’t really feel them bombarding us.  We don’t sense those signals without some mechanical help… but they strike us with many different frequencies constantly… so let’s explore the range of frequencies we can decipher with a homemade crystal radio set!

Crystal Radios. A blast from the past!

Many of us have looked at, or even built a crystal radio set at some point in our lives. Maybe it was in our Scouting days, youth group, science class, science fair… or just to DO IT!  The circuit itself is relatively simple to wire-up.  A long piece of wire acts like an antenna.  Some configuration of earphones or speaker will let you listen to signals.  And believe it or not, the signals are all around you!  The local AM radio station should be easy to hear.  You can even build a simple pre-amp (pre-amplifier) circuit to boost the incoming signal to add extra volume and signal strength to the fun.

Let’s understand WHY a crystal radio set is sooooooo cool!  SIMPLE CIRCUIT DESIGN.  EVEN KIDS CAN DO IT!  EASY TO GET PARTS.  NO EXTERNAL POWER REQUIRED.  INTERCEPTING INVISIBLE RADIO WAVES THAT ARE ALL AROUND US.  Plus, it’s just a pile of fun!

Here is a YouTube video from WonderstruckHow who teaches us to build a very rudimentary crystal radio set with parts that are easy enough to scrounge up.

After you watch the video check out the picture gallery of all sorts of crystal radio sets that can be built in just a short time.  They are great for kids working on a science fair project (and sure beats out a terrarium!)  Some of us “Seasoned Citizens” might actually remember the paper towel tubes or Quaker Oat cardboard cans we wound the magnet wire around and even some of the commercial kits sitting under our Christmas tree!

Straight Key Night… FUN!

Every January 1st there is a fun filled evening of laid back, “no pressure” CW (Morse Code) operating using a simple “Straight Key” to key your transmitter without the aid of added electronics to perform the speed and spacing of your sent letters and numbers.  This isn’t a contest!  It is designed for fun sending CW the “old fashioned” way.  The object is to simply enjoy sending and reading Morse Code.  There are numerous configurations and sizes of straight keys and a jaunt down any ham radio flea market aisle will often give you quite a few options for a great purchase!

Here is a video example of the annual Straight Key Night experience. MIKROWAVE1 explains and actually makes CW contacts with other amateur radio operators enjoying the annual event. (Below the video, look for some pictures of several types of straight keys you might find as a bargain to add to your own ham radio station!

Here are some pictures of various CW (Morse Code) keyers.  You can grab several to use for contesting or just simple rag-chewing.  Some hams actually collect various types of keys!

 

 

Famous Ham Radio Operators and their Callsigns

I love learning who shared our favorite hobby… and the list is very long!  It was so interesting to see not only WHO they were but also WHAT they did to be famous.  Literally from every corner of the globe (try and find a corner on a globe).

samuel-morse_postage_stamp

I found this on the DX-QSL website and somehow the Bedworth Lions Club apparently had something to do with the creation of the list.  I am quite fond of the good work The Lions do and I belong to a couple fraternal organizations (Masonic Lodge and Woodmen of the World) myself, so I am sure there is a story about The Lions being connected to this list.  The list is long, so grab a refreshment and enjoy!  Be prepared to be surprised!

Amateur Radio, Radar, Lidar & Radio on Postage Stamps

I love  collecting stamps and vintage baseball cards and have quite a collection of both… but I have NEVER seen this many RADIO STAMPS in one setting!  Kirt Blattenberger, KB3UON, has a really cool website with lots of neat things to read.  This caught my eyes INSTANTLY.  Thank you, Kirt!  His quote and stamp array begins below.

************    ************    ***********    **********    ***********

Over the past many decades, my involvement in stamp collecting (philately) has waned and ebbed with the amount of time available to dedicate to it. Commemorative stamps – from all countries – have always been of the greatest interest to me. Even if you are not a philatelist, your interest in radio should be piqued by the large number of postage stamps that have been issued in radio’s honor. Although I do not own most of the stamps pictured here, there are some that are in my collection. This is a small cross-section of what is available. Over time, I have added to the list and will continue to do so. Please let me know if you have relevant stamps to add.

I was amazed to discover how many countries have postage stamps recognizing the important role that weather radar has played in history.

What Is D-Star All About?

Yaesu has System Fusion… guess who has this thing called, D-Star?  You can probably guess pretty quickly, if you don’t already have an idea.

Discover D-STAR from Icom

Yaesu System Fusion Introduction

Cory Sickles (WA3UVV) is active in our local ham club, Monongalia Wireless Association, and he has been guiding us in installing a new Yaesu System Fusion repeater system up on Chestnut Ridge.  Are you wondering what Yaesu System Fusion is?  What is C4FM?  What is the difference between Fusion, D-Star, P25 and DMR?  Well… here are a couple videos that might give you some insight into primarily Fusion… but the second video looks at some comparison.  (Spoiler alert… it gets territorial quickly.)  Hats off to HamRadioOutlet and HamRadioNow for spending the time on these cool systems!

Near Vertical Incidence Skywave (NVIS)

ml91_graph-779367

I love DX.  I love chatting to interesting people all over the world and making new friends.  For short range chatting I use our Monongalia Wireless Association W8MWA Repeater on the 144/440 frequencies.  Sometimes it’s more difficult to talk short distances than it is to talk half way around the world.  Let’s consider Near Vertical Incidence Skywave  (NVIS) antennas with our HF radios.

NVIS is something every Ham needs to learn about.  The antenna system is not difficult to construct and can serve an important function for shorter range communications, especially in time of an emergency when normal local / regional communication systems are down for some reason.  (i.e. cell towers, cellphones, landlines, etc.)  Hams may be called into service quickly.

Here is what Wikipedia says about NVIS communications…

Near vertical incidence skywave, or NVIS, is a skywave radio-wave propagation path that provides usable signals in the range between groundwave and conventional skywave distances—usually 30–400 miles (50–650 km). It is used for military and paramilitarycommunications, broadcasting,[1] especially in the tropics, and by radio amateurs. The radio waves travel near-vertically upwards into the ionosphere, where they are refracted back down and can be received within a circular region up to 650 km from the transmitter.[2] If the frequency is too high (that is, above the critical frequency of the ionospheric F layer), refraction fails to occur and if it is too low, absorption in the ionospheric D layer may reduce the signal strength.

The most reliable frequencies for NVIS communications are between 1.8 MHz and 8 MHz. Above 8 MHz, the probability of success begins to decrease, dropping to near zero at 30 MHz. Usable frequencies are dictated by local ionospheric conditions, which have a strong systematic dependence on geographical location. Common bands used in amateur radio at mid-latitudes are 3.5 MHz at night and 7 MHz during daylight, with experimental use of 5 MHz (60-meter) frequencies. Broadcasting uses the tropical broadcast bands between 2.3 and 5.06 MHz, and the international broadcast bands between 3.9 and 6.2 MHz, Military NVIS communications mostly take place on 2-4 MHz at night and on 5-7 MHz during daylight.

Optimum NVIS frequencies tend to be higher towards the tropics and lower towards the arctic regions. They are also higher during high sunspot activity years. The usable frequencies change from day to night, because sunlight causes the lowest layer of the ionosphere, called the D layer, to increase, causing attenuation of low frequencies during the day [3] while the maximum usable frequency (MUF) which is the critical frequency of the F layer rises with greater sunlight.

NVIS is most useful in mountainous areas where line-of-sight propagation at VHF or UHF frequencies is ineffective or when the communication distance is beyond the 50-mile (80 km) range of groundwave, and less than the 300–1500-mile (500–2500 km) range of lower angle sky-wave. Another interesting aspect of NVIS communication is, that direction finding of the sender is more difficult than for ground-wave communication (i.e. VHF or UHF). For broadcasters, NVIS allows coverage of an entire medium-sized country at much lower cost than with VHF (FM), and daytime coverage similar to MW (AM) nighttime coverage at lower cost and often with less interference.  https://en.wikipedia.org/wiki/Near_vertical_incidence_skywave

Below are a few very good links to articles for the nuts & bolts of putting together a simple and good NVIS antenna.

If you are going to build a simple crystal radio, a QRP rig or even a 100 Watt HF transceiver, you are going to want to understand how an electronic schematic diagram is read.  It’s not that difficult.  RimstarOrg has a great video on understanding the basic concept of reading a schematic.

 

Multimeter Tutorial by AfroTechMods

THE BEST Multimeter Tutorial

The voltmeter… the Volt-Ohm Meter… the Multimeter… digital or analog… continuity… amperage, voltage and ohms… COME ON, MAN!  What is it and how hard is it to use in the every day life of a ham radio enthusiast or just someone working in their workshop?  Once again, Afrotechmods has an excellent tutorial on his YouTube channel for us to learn from!

Regardless if it’s your flashlight, your 2 Meter hand-held radio, your QRP rig, your Field Day station(s), your APRS setup, your balloon launch radio transmitter, your trolling motor, your emergency preparations or your personal GoBox… understanding how long those batteries that supply operating power will last becomes quite important.  It will also assist you in deciding what battery to select for a particular project or product.  Afrotechmods has several excellent YouTube videos on his channel that we all can enjoy!

Does Volts or Amps Kill You? Voltage, Current and Resistance

This should be a good lesson for everyone, especially Hams that tinker and homebrew serious radio equipment.  You’d be surprised how much is too much!  Safety around radio equipment, coaxial cables, power chords, power lines, lightening storms, grounding straps and towers needs to be at the forefront of our mind.

Portable Battery Box for Kayak… or Ham Radio

There are a ton of variations of portable battery boxes and unbelievably expensive if you buy they retail.  I like building projects at home, so here is another battery box with a very different form profile from some of the other videos on my blog.  DIY!  Here is a video from Derek Dickey on YouTube of his own kayak fishing GoBox.

 

Portable Power Box

Battery Box, Simple Portable Power by KC6TYD

I built a portable battery box years ago out of a used small white lard tub from a Mr. Donut shop here in town to carry 2 small batteries to power “things” on camping and canoe trips.  It charged from a flexible solar panel that I laid atop my packed canoe when fishing on the rivers of West Virginia.  Then at night I had a string of 12 volt car lamp bulbs that I would string up around the campsite for some excellent lighting.  It also had a small LED inside the box that would glow amber all night so that if you needed to get up in the middle of the night you can set the small tub beside the tent flap and push a little button to kick on the rest of the lights.  I like this set up from KC6TYD, too!

GoBox Ideas

GoBox Update from KC6TYD

I am getting ready to put my ham radio station back together after being QRT for a number of years.  When I think about the VHF/UHF section of my station, I may decide to configure those particular technologies in a GoBox, of some sort.  I really like the idea of being able to “pack-n-go” in the event of emergency comms or Field Day type of activities.

 

Back Up Solar Power for Ham Radio

Harbor Freight Solar Panel for Ham Radio

I spent a lot of time on a medical mission trip to Mali, West Africa years ago optimizing their solar power system.  (Constant dust on the solar panels from the Harmattan winds was a battle for efficiency.)  This is an interesting video done by KC6TYD about his first experience with solar power in the ham shack.  (This only about the concept, not an endorsement per se of Harbor Freight or the manufacturer.)  But I am definitely interested in some solar projects here at home in the future.

2015 ARRL Field Day

Tom and Bill work on configuring Ham Radio Deluxe DM780.

Tom (KD8DQK) and Bill (WR8S) work on configuring Ham Radio Deluxe DM780 for our ARRL Field Day stations high atop the mountain.

Well… the 2015 ARRL Field Day adventure is in the books… the logbooks, that is. Having experienced decades of Field Day excursions, this one takes the cake!  What started out as a hot, sunny, humid Friday afternoon setting up our station high atop Chestnut Ridge, ended on Sunday afternoon having operated under conditions of torrential rains, a downward shift of 40 degrees in temperature, one antenna failure, one operator unable to man a station due to illness, a generator choked-out by all the moisture in the air and eventually walking around in a literal cloud!  We had three layers of clothes on and could see our breath on Sunday morning!  To say the least, it was a unique set of challenges to overcome.

Plan A was to slingshot and hang 3 doublet antennas, run 2 KX3’s for CW and PSK31, and run an Icom 7200 with a new Heil Pro 7 headset on voice.  We had a 5500 watt generator and 25 gallons of fuel to keep us purring along.  With 4 operators we had a good chance to keep all rigs racking up points for the duration.  Laptops were ready to log and the plan sounded solid.  The goal was to beat our score from Field Day 2014 and thought a good mix of voice and data would do the trick.

Our usual set-up has us mooching off of WR8S’s generosity when he goes to the trouble of of hauling his camper to the top of the mountain.  We extend the awning and set up a table or two to operate from.  Field Day 2014 was done via battery power and QRP mode.

WR8S and WD8DQK bundled up... oh wait...WR8S only brought shorts!  Wins endurance award!

3 layers of clothes with hands so cold it was difficult to run DigiPan for PSK31 contacts.

WT8WV with 3 layers of clothes and hands so cold it was difficult to run DigiPan for PSK31 contacts.

The video below is a typical contest exchange using CW (Morse Code) and in the ARRL Field Day Contest an exchange of information would be the call sign of the other station, your operating mode (how many radios are you running and what sort of power and station are you running), followed by your section of the country.  Then you return your own exchange to the other station and move on the to next contact by calling “CQ FD CQ FD de WT8WV WT8WV” and hope for a return of your call sign for a confirmed contact to log.  CQ means “calling anyone”… FD means your are calling for the “Field Day” contest… de is French and means “from”… and WT8WV is our station’s “identifying call sign”.  (You will see Bill (WR8S) make a contact and then write down the exchange from the other station on the log paper… then he begins calling CQ FD CQ FD de WT8WV using a memory keyer that he can program with the CQ message, our contact information and a thank you good bye message.  He just needs to use the keyer paddles to send the other stations call sign during a contest.)  Our return message to the other station to enter into their own log was, “WT8WV 2A WV”.

The pictures below tell the story of our challenges and our solutions.  I have to admit I thought we were DOA when the generator croaked at 4:30 am on Sunaday… but we quickly came up with Plan X and realized WR8S had a converter in his truck!  Back to battery power to finish of a good run of PSK31 and CW for 2 points each!

The original team plan was to use my new call sign WT8WV and be “3 Alpha West Virginia” but Jay got sick on Friday so we were now down 1 team member and 1 radio.  Then we had a balun issue with 1 doublet antenna.  So now we are WT8WV 2A WV with 2 Elecraft K3’s and 1 antenna.  We decided to salvage our potential scores by focusing on PSK31 and WR8S’s speedy left hand on CW… and forgo voice comms.
