Digipeating: APRS to the International Space Station – At Your Convenience
By Richard Fisher KI6SN

Making contact with the International Space Station by amateur radio is challenging on its face—the ISS orbit must be somewhere above your horizon; it is a moving target, and your antenna needs to be tracking its position as the space station moves across the sky. For FM voice contact, you may be in competition with lots of other Earth-based stations with the same goal as yours. But, thanks to the ISS’s digital repeater, contact with ISS is quite possible, but even so, for success, there are still lots of stars that must align. Richard tells us how it’s done.

TSM Reviews: The Mobile VHF/UHF COMPACtenna
By Bob Grove W8JHD

Is it possible for a 7.5-inch antenna to provide equal, or even superior, performance compared to a conventional 18-inch whip? After all, doesn’t a longer element capture more signal energy than a smaller element? Even with some reduction in signal strength, would overall improvement in uninterrupted reception translate to better performance? Bob examines this new mobile VHF/UHF antenna.

TSM Reviews: COMPACtenna for Shortwave
By Chris Parris

Chris was recently offered a chance to use the COMPACtenna SW (shortwave) model at home. The “SW” specifications show that it is 20 inches tall, designed for continuous receive over 3 MHz to 30 MHz and uses a standard 3/8-inch – 24 thread mount that most CB antennas are designed for. As someone who has tried for many years to find a good mobile/portable shortwave antenna solution, this seemed too good to be true. He decided to take the COMPACtenna out and try it on his personal vehicle along with several radios and other shortwave antennas to see how it fared.

RTTY: Old School Digital
By Cory GB Sickles WA3UVV

In his previous articles about other forms of digital communications as well as his three-part series on “Piggy Bank Ham Radio,” Cory found that there appears to be a good deal of interest in radioteletype and a desire to use some older gear. Coupling that with questions about pre-1990 HF rigs, there would seem to be a convergence of ideas. While older gear may not be suitable for the latest in digital modes, they are still perfectly fine radios and the fun of RTTY awaits you – with several ways to get on the air. Cory traces the history and continued use of this vintage amateur mode.

CRKits HT-1A Dual Band QRP Transceiver
By James Hannibal KH2SR

This dual band transceiver, available as a kit or factory-built, has a transmit frequency range of 7.0-7.2 MHz and 14.0-14.35 MHz. And, even though it only transmits CW, it does have the ability to listen to SSB signals. It also has an extended receive range, covering everything between 5.9-16 MHz, which means shortwave broadcast reception while in SSB mode. James puts this little rig to the test as it was meant to be used, outside in the wild with a small battery pack and portable antenna.

Millen’s Ham Superhet: The National FB-7

The Spectrum Monitor is available in PDF format which can be read on any desktop, laptop, iPad®, Kindle® Fire, or other device capable of opening a PDF file. Annual subscription is $24. Individual monthly issues are available for $3 each.

It is my observation that by enabling someone a taste of what can be accomplished on HF (shortwave) spectrum, especially using one of the newer digital modes, that someone has an opportunity for inspiration, perhaps enough to catch the HF fever that is required to move that someone from entry-level to experienced, skilled expert. Right now, the regulations limit the Technician-level license holder to digital operation only on bands that barely propagate (if at all!) during the weak solar cycles. It is a far stretch to postulate that having privileges on dead bands will inspire exploration and tempt the operator to upgrade to a higher license class.

I believe that Technician-class priveledges should be expanded so that entry-level amateur radio operators can get a practical taste of effectively-propagating HF signals on lower frequencies than those frequencies currently available to them for digital operation. And, the allowed mode on these subbands should include digital modes. This “would encourage a sustained interest in Amateur Radio and encourage further development of knowledge and operating skills,” a concept already proven by General-class operators that get enough of a taste that they then pursue the Amateur Extra license.

Comments to me are below the following video section. I also include my response.

In the following video, I share my opinion regarding the ARRL asking the FCC to grant more operating privileges across the many amateur radio allocations on shortwave (HF, or, High Frequencies). The video is my brief takeaway of ARRL’s petition: What is the issue, as a whole, and what the ARRL is addressing–the lack of desire by most current Techs to upgrade. The logic of my perspective concludes that if you give them a taste of lower-shortwave propagation and excitement, then they will want to upgrade. This logic is already proven as applicable by the fact that the General class exists. All this proposal will do is allow the tech to experience what could be very attractive. Just like for the General.

I made a few technical mistakes in the first video. The last video contains corrections and further comments.

Comments Received, and My Response

I have received many responses–some in opposition, some in support. Here are example contrarian responses along with my reply:

[Dear] Tomas David Hood[:] Something for absolutely nothing has never taught anyone anything good, but to want another free lunch. 35 multiple guess easy questions was all that was asked to get general class privileges, but that’s just too hard for the current class. Something for nothing is what sell today, and the ARRL, and probably half the country thinks socialism is the way to reach the new hams I guess. But the ARRL will never get another dime from me. You want a trophy or additional privileges, Get them as everyone else did,, Work for them, study, just a little is all that was asked. Remember, If it didn’t cost anything, it probably isn’t worth anything!

If they are not willing to take a simple test, and yet they want to upgrade, then yes they are the same as saying that we are asking too much, but would participate, you are suggesting, as long as it didn’t require any work or effort on their part, Its a shame.. And I am embarrassed on their behalf… Alexandria Ocasio-Cortez could pass that test, but she would probably agree with you, that people are asking them to be smart and study, and that’s somehow probably racist and just over the line for you.

At this point the ARRL should just say, we are not protecting the spectrum, but about selling the ham radio spectrum to the highest bidders. In this case, they be;live that will be the techs who will purchase HF gear, and of course, the ARRL will benefit hugely from the equipment makers desire to market to the group.

My response is:

What the heck is wrong with selling radios?

But, seriously, which of the many Technicians say that they want to upgrade? That’s the point: the majority of Technician-class amateur radio operators are not upgrading. They get on VHF and above, and are stationary, with few realizing that there’s so much more than the aspect of the hobby evident in their local community.

With little to no exposure to other aspects of the hobby, the typical ham in the current ham-radio culture settles for what is presented by local mentors. Weather spotting, DMR, etc.

Because they have current HF privileges that have so little practical use (CW only on lower frequencies; voice on 10 meters which doesn’t propagate well during this period of no sunspot activity…), they see no incentive to delve into what appears like a waste of time.

The proposal is not giving away the farm. It simply adds a small slice on a limited set of HF bands (but where a signal has a better chance of propagation), allowing for Technician-class operators to get a real sense of the potential waiting for them if they pursue the General.

Then, once upgraded to General, they get even more exposure, and hopefully, see why it is great to be an Amateur Extra.

Tomas David Hood what’s wrong with selling radios. Nothing at all, but if I removed the test that drivers take to show they understand the rules and how to drive, then I can sell more cars and more insurance to poor drivers. Do you or anyone else think that’s a good idea. A few tech’s putting their hands on the plate of those high voltage amps, and maybe, just maybe, someone will believe me when I say some basic testing should be required for HF privileges. Now, all they will have is a cereal box license in my book, and in the opinion of many of my friends, so it;s not just me. If I am wrong, then there are a lot of people that are wrong like me, and they will fight for there hobby. I am a ARRL VE, but I will never test another Ham if this goes through, and I will spend the rest of my days making sure any newcomers realize what the ARRL did to what once was a good hobby, and how a few people didn’t seem to understand why giving away free privileges is always bad for our society, and always bad for our hobby.

Actually I have a real case study that is local,, and yes the guy doid put his hand on the plate, and yes he hit the floor.. and yes, after I found out he was ok,, I think it’s plenty funny,, Yes, they need to study more than that.

Me:

Your argument that Technician-class operators will kill themselves because the test is so easy that they will end up electrocuting themselves is yet another Red Herring. Technicians play with dangerous VHF, UHF, SHF equipment, with ominous dangerous aspects deserving respect. If you really think that the General test is the difference between life and death, why even worry? The number of technicians will be nicely reduced to a more acceptable, comfortable number.

I’ve seen Amateur Extra-class operators do the same sort of dangerous, life-threatening stunts.

The issue you are highlighting is a different problem that must be solved separately from the idea of creating a more practical incentive; all tests should be improved in such a way as to foster greater technical knowledge and awareness of all aspects of the hobby.

Better mentoring. Less us-vs-them. More education. More community. All of these should be explored and enhanced. Solve the problem, instead of ostracizing. And, realize that this proposed change is NOT a dumbing-down maneuver to give away the ham radio hobby to the unclean.

Traditionally we’ve seen radio direction finding (RDF) in the form of Doppler kits and tone meters, however with the proliferation Software Defined Radio (SDR) we’re seeing a new form of direction finding.

Essentially if you take four software defined radios and coherently link them together, you can then compare the signals from four separate antennas to get a bearing of your target signal’s location.

I recently came across a project on Indigogo which offered this in a complete package called the KerberosSDR. Here is a video of my setup and a demonstration of this radio.

https://www.youtube.com/watch?v=n5aWrz-42qc?rel=0

The KerberosSDR is still under development, but from my tests it works fairly well. Unfortunately, I don’t have any traditional RDF gear to compare it to but from what I’ve seen it’s certainly a potential way to go if you’re looking to have some fun with RDF and want some more modern gear.

If you’re interested in the KerberosSDR, you can find more information about it here:

TSM Reviews: Uniden SDS100 Base/mobile Scanner
By Larry Van Horn N5FPW

On the heels of the release of the SDS100 handheld scanner in the first quarter of 2018, Uniden announced the release of the SDS200 base/mobile scanner in January 2019. Like the SDS100, the SDS200 is a True I/Q™ scanner, that incorporates software defined radio technology to provide improved digital performance in even the most challenging RF environments.

What sets the SDS100/200 series scanners apart from any others in the marketplace is their ability to handle simulcast reception issues while monitoring certain P25 trunk radio systems. Larry takes a look at this talented scanner in part two of “The Good, the Bad and the Ugly.”

Bringing Ham Flavored STEM into the Classroom
By Martha Muir W4MSA

Members of the North Fulton Amateur Radio League (NFARL) spent a week working with some seventh and eighth grade students at Mill Springs Academy in Alpharetta, Georgia, teaching them some fundamental concepts of electronics with direct applications related to amateur radio. This is part of a program at Mill Springs called Winter Learning, where students get to take a weeklong seminar on a specialty topic. This specialty topic, “Electricity is Magnetic!” was organized by NFARL members, Chuck Catledge AE4CW and Jim Stafford W4QO. Martha tells us what happens when Science Technology Engineering and Mathematics meets amateur radio in the classroom.

Portable Airband Transceiver Overview
By Cory GB Sickles WA3UVV

The VHF spectrum is full of FM analog and various forms of digital voice and data communications, but also found there are communications based on a technology that goes back a century and then some—AM or Amplitude Modulation. This is the type of signaling shared by commercial and general aviation pilots, as well as the men and women on the ground that communicate with them to keep everyone safe and moving efficiently. If you live near an airport of any size you may have wondered about listening in. Cory takes a look at listening to this small but important slice of the spectrum.

Othernet’s Free Satellite Service Continues to Evolve
By Kenneth Barbi

The free one-way digital satellite service, known as Othernet, has been evolving since its debut in 2017. Othernet had operated first on Ku-band and then on L-band, and though coverage was worldwide, the cost was astronomical, and the throughput was limited to 20 MB per day. By reconfiguring their operation back to Ku-band, costs came down and throughput increased to more than 1 GB per day. But the change required different hardware. Kenneth updates the latest on this non-profit information service.

Prologue…

I was born in 1932, which by definition made me a depression baby. This episode in the life of Urb the emerging nerd, demonstrates that people were totally capable of doing economically irrational things during the height of the depression. They would throw things away needing only simple repairs.

How it all began…

At the time my trash picking started I was in 7th grade and I was the only student living far enough away from school that I couldn’t make it home for lunch, and back, in the allotted hour. I was a brown bagger.

On an early beautiful spring day I was walking leisurely to school and there in front of me was a beautiful floor lamp. I realized that if I waited until school let out the lamp would have been long deposited in a landfill (we call them junk yards back then.) I picked it up and started walking toward school. About two blocks from school was an empty wooded lot. I put my lamp in the lot and camouflaged it with a few branches and continued to school. I agonized all day worrying that someone would abscond with my lamp.

After school, there is was. I took it home and showed my father and he determined that the lamp had a switch that was not functioning, we went to a local hardware store and purchased a new one. (Home Depots didn’t appear for many decades into the future.) Lamps similar to my trash pick find were selling for about five dollars of 1940s money.

A new switch cost about 20 cents. Although my knowledge of the consequence of the depression was very limited I still found it strange that people would throw away a five dollar lamp because it needed a 20 cent switch. The lamp, with a new shade, occupied a place of honor in the LeJeune household for years to come. My mother, God rest her soul, was very excited about anything I did not requiring a trip to see the principal of my school.

After the experience with the lamp, I started leaving for school about a half hour earlier that I usually did on trash day. One day someone threw away a pair of roller skates (the type you attached to your shoes and tightened with a key.) I fashioned a wagon with a milk box and the skates. I was now ready for the big time of trash collecting. I made a camouflaged den in the lot close to school and was in the trash picking business.

Turning Trash into an Art Form…

Even I was amazed at the quality and variety of things thrown away despite the economic conditions . When a discarded item contained gears I was in Trash-Land heaven. If a discarded item contained a motor, functioning or not, I was in paradise. Thrown away items with gears were especially prized, I used gears mounted on a piece of plywood to make Christmas presents. My relatives told me how creative I was but my artwork typically wound up on their basements wall.

At Christmas time I loaded some of my artwork into wagon and traversed my neighborhood selling my wall hangings. When people asked how much? I replied, “whatever you think it’s worth.” I made enough money to get nice presents for my mother and father.

Spare Parts…

Growing up my family lived in half of a farmhouse. I had a corner of the basement all to myself. My little den served as workshop, storage area, and a laboratory for perform experiments. My attempt at making artificial diamonds was a barn-burner but an article for the future.

Epilogue…

An event viewed through the key-hole of currency frequently takes on a greater meaning when viewed through the rear-view mirror of realism. As an example, the fact that I lived at a greater distance from school than any other student probably lead me to trash pick. If I walked to school with other students I doubt I would not have trash picked.

I went through a period between jobs, a nice euphemism for being unemployed, and money was tight so I put my trash picking days to good use. On the bulletin boards of local super markets I posted notices, “Small appliances repaired , no fix no pay.” The results were a God-send when satisfied customers recommended me to neighbors and friends.

When times are tough we frequently receive the emotional help to give us the strength to get through these period, if we are alert to them.
