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

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.
