I Am Back After Life Distractions
The last three years have been, well, challenging.
In 2021, I became ill with Covid. That was rough, but I bounced back. That bout with illness caused me to lose my job, though, because I was ill too long. What is worse is because I was not hospitalized, I did not fall under the protections of “disability,” and had to step down from my employment at that time. After I recovered, I found employment.
In 2022, I again fell ill to a second Covid. That illness was significantly worse! I nearly WAS hospitalized, but I resisted this, and hung on by a thread. I made it through, though the illness lasted a lot longer the second time around. Because I was ill for about five months, I again had to step down from employment. This second Covid was the worst illness I have ever experienced, physically, emotionally, and financially. I am thankful for my friends and family that were very supportive.
After I recovered, I found employment in late 2022. It took a while for my health to stabilize, but the new job leadership has been supportive. I have been happily working at this new job since late 2022.
But, the challenge to recover was high. I sought answers.
In December 2022, I was diagnosed with Primary Hyperparathyroidism. Sure enough, the many tests I endured confirmed that I had more than one tumor in at least two of my four parathyroid glands (we each have four of them, because we’re given redundancy for this critical body part).
I had surgery at the end of February 2023 to remove these tumor-riddled glands. The surgeon, once in my neck, found that THREE of my four glands were tumorous! He removed the three. I now have just one parathyroid gland.
Recovery has gone well. My health is improving nicely. It is like a switch was flipped, and I no longer have some of the debilitating symptoms like brain fog, extreme fatigue, and an out-of-control metabolism. I have a stable function of the remaining parathyroid gland, and that is supporting the proper function of the rest of my body. It is amazing how the whole body relies on these four glands for running correctly!
All of these challenges of the last few years caused enough distraction that my YouTube channel, and my writing, here, as well as other hobby activities, suffered my absence. Now that I am getting back on my feet with my health, and because my job continues nicely, I am beginning to spend some energy and time on these hobby areas. I plan on creating and releasing a few series on amateur radio, radio propagation, and space weather, on my YouTube channel. If you are already a subscriber, you probably saw my latest video where I announce that I am, indeed, back:

If there are topics that you would like me to cover in the new educational videos I am planning and will create, please let me know with a comment to this post, or, look my email address up on my profile at QRZdotCom. I will do my best to answer your questions and cover amateur radio and space weather topics in which you are interested.
If you are not yet familiar with my YouTube channel, you can find my channel here: https://YouTube.com/NW7US — Please subscribe and hit the bell to be notified when I release new video content.
I will also post more often on this site. I appreciate the opportunity to share with you my love of amateur radio, and the science of propagation and space weather which affects our radio signals.
Best regards,

There are almost as many GMRS licenses as Techs…
At a recent local hamfest, my ARRL Section Manager, Malcolm W5XX, held the annual ARRL Forum. As Division Director David Norris K5UZ was giving his update on the recent Board of Directors meeting. W5XX commented that a club in North Georgia had begun reaching out to licensees of the General Mobile Radio Service (GMRS). Why? There are some 8,000 of them in surrounding counties! Give a statistician a number like that and it’s catnip to a cat.
I had heard of GMRS and the lighter-weight Family Radio Service (FRS) as additional radio frequencies to the famous Citizen’s Band (CB) that I used as a teen. But I didn’t really know much about it. So, I spent parts of a week doing some searching, reading, and, inevitably, database building. I saw the wisdom of the club in question reaching out to this audience. Let’s do a thought experiment to flesh this out.
GMRS licensees use radios up to 50 watts on mobile stations and 15 watts in fixed stations in the mid-400 mhz region. There are limitations on the type of one-way communications (no whistling which would rule out most anyone in amateur radio tuning up an amplifier, lol). But in general, there are parallels to GMRS operators to those holding a Technician license in the Amateur Radio Service with the latter having much greater frequency access, power usage, and other aspects of the radio arts.
After doing some reading, I checked the FCC ULS GMRS license data. There’s an interesting comparison: the ARRL February 2023 numbers show 386,122 Technicians while individual GMRS licenses total 336, 513 after APO addresses and one Canadian are removed. Organizations and some other groups can obtain GMRS licenses. Roughly, there are about as many individual GMRS licensees as there are Technicians, give or take 50,000. Ok, I thought, this is surprising but how do they operate? Are they communicating amongst themselves as ham operators do? How many GMRS repeaters are there? The surprises just kept on coming!
The popular site, RepeaterBook.com, does list some GMRS repeaters. But the mother ship is the myGMRS.com website. One has to have a GMRS license to register but there ‘s enough information available to the public to show just how organized parts of the GMRS community already is. I’ve taken a screenshot of the map display, nicely done with clustering repeaters until a certain zoom level is reached, showing the GMRS repeaters in the U.S. Note those in Puerto Rico: I had recommended that the ARRL assist in getting a permanent repeater on the westernmost mountains near Mayaguez after a devastating hurricane. Perhaps even an HF ALE type station directed at Florida or North Carolina. Looks like the GMRS community has done some work here, too.
The map below illustrates the set of repeater hubs and their links around the U.S. There are national and regional Nets held regularly. An audio stream can be monitored using the website for each hub, not unlike Hoseline for the Brandmeister DMR Network. Hmm. If ham radio were only this organized, so quickly.
After downloading the February 2023 GMRS data from the FCC ULS ftp site, I processed it and filtered out the overseas military licenses. These records were then georeferenced to street addresses, with some that did not have street addresses geocoded to zip codes and a few to city centroids. The map below illustrates this: the GMRS individual license IS a compelling market for amateur radio recruitment.
It’s easy to see that the North Georgia region is part of the Appalachian Mountain range that is covered with GMRS licensees But so is most of the region east of the Mississippi River, the West Coast and the mountainous areas of the Southwest. Here’s another view zoomed in to the ARRL Delta Division where I live. Licensees in GMRS tend to follow population centers but note the areas, like Nashville, where the topography gives more height-above-ground than others. Northwest Arkansas is another such location. Interesting patterns!
We know little to nothing about the age distribution of GMRS licensees as year of birth is not contained in the ULS database released to the public (only 18 or over). But it stands to reason that GMRS licensees are likely to have a broader age range of adoption. From perusing the names on the licenses — license holders can authorize other family members to use additional radios in this Service — there are gendered-naming patterns. More women in GMRS than ham radio? Possibly.
Some interactive maps of these data are now available over at FoxMikeHotel.com under the Maps tab.
An important note is that an unknown number of those holding GMRS licenses today also hold licenses in the Amateur Radio Service. The FRN is not contained in the GMRS data so it would take “fuzzy matching” with less than perfect results to examine this idea.
The ARRL has taken an interest in my proposed initiative to treat public libraries in the U.S. as “new served agencies” for recruitment strategies, according to Division Director David Norris K5UZ. See my two blog posts here and here. Should the GMRS licensees be viewed as another direct marketing opportunity by the ARRL?
I’ve taken the GMRS data and spatially joined the ARRL Division and Section fields to the license record using GIS. These files were then split into separate spreadsheets by Division with the Section as a separate field. I’ve put them on my public folder in Dropbox for all to retrieve should they desire. This would make it easy for a direct-mailing to GMRS licensees. In a cover letter identifying the contact info for their ARRL Section Manager, a brochure should be inserted describing the much greater options available by adding the Technician license through a VE exam. It works for some yield rates for other membership services. (Check today’s mail if you doubt this isn’t used frequently.)
It would not be inexpensive with USPS rates. But it would be directed at a market that is already known to have some interested in operating radios for communication. Perhaps it should begin with GMRS licensees in areas where there are existing repeater operations. This would be a good test case to see the yield from such a direct mailing.
What won’t work is to simply send the information “down stream,” expecting SMs to do all the heavy lifting. It simply won’t happen. The League already conducts a commercial mailing operation which is where this activity should be situated.
This would be a third recruiting rail for the ARRL, including the Teacher Institute (getting in schools), the pending (I’m told) Plant the Seed initiative for public libraries, and the direct mailing to known radio communication licensees in the GMRS arena. Recruit the Generals, anyone?
What Headphones Do You Use, And Why?
What headphones do you use for your radio operation, and WHY do you use that particular make and model?
I use Audio-Technica ATH M30x professional monitor headphones (cans).
https://www.audio-technica.com/en-gb/ath-m30x
I use my rig’s filters to shape the audio.
1. I’ve replaced the over-the-ear pads with Gel pads. Wearing these cans is comfortable enough to use for extended periods of time (such as contests).
2. The mid-range with these cans is superior to other cans I’ve had.
3. They are rugged, so taking them out to the field isn’t a problem.

Unexpected Surprise: What Are The Odds? ATNO DXCC
I have a story for you. All of it is true, but I have not changed my name.
Wow! I am always amazed at those moments in my amateur radio hobby when spontaneous joy is had by unexpected events.
On Thursday, 14-April-2022, at about 17:30 Universal Time (UT), the unexpected occurred, and it started by accident.
I have been reorganizing my radio shack. Once I moved my main transceiver (the Icom IC-7610) from one desk to another, and had it back in operation, I left it tuned to a random frequency, in the CW mode. It was just sitting there, hissing away with the typical shortwave sounds of a frequency on which no one was transmitting. And me? I was going about reorganizing my radio shack.
After a while, I heard the start of a Morse-code CW signal; the operator was sending a CQ call–a transmission that invites a response from anyone who wishes to have a QSO with the calling station. What I heard was, “CQ CQ DE EP2ABS EP2ABS…”
NOTE: This transceiver, my Icom IC-7610, is listening with the new antenna—the 254-foot doublet up at 80 feet–that was raised up into the air here at my QTH by a fine crew from Hams in the Air.
I looked up EP2ABS on QRZ dot com, because I did not know from what country/entity the EP2 prefix on callsigns belongs. I was excited to see that EP2 is from Iran!
I started answering his CQ call, “DE NW7US NW7US,” for at least ten minutes; each time he sent his CQ, I answered. Finally, I heard him answering me, “NW7US NW7US DE EP2ABS 5NN…”
I answered back, sending my signal report, “5NN 5NN DE NW7US TU”
Soon after that simple exchange, he confirmed our QSO by posting our QSO to Logbook of the World (LotW).
Thus, by accident–as I had simply left the transceiver tuned to a randomly-selected frequency and stayed on that frequency listening while doing my chores–I heard the Iranian station calling CQ. What are the odds!?!?
This is my first QSO with Iran, another All Time New One (ATNO). How cool!
Note: This is a testimony to the work from the crew that did the fine work of getting this antenna installed. Here is a video presented by Hams on the Air:

Part 2 of 2: Life-changing Moment and Solar Cycle 25
From the RAIN HamCast episode #57, 2021-XII-25 (used with permission):
RAIN’s Hap Holly/KC9RP spoke with Tomas recently about Solar Cycle 25. This is the second and final excerpt from their discussion.
From the introduction to The RAIN HamCast, Episode #57:
In this episode, we continue our discussion with Tomas Hood/NW7US, the author of many writings about space weather and effects of solar activity the past 20-plus years.
(Part 1 of 2 can be found here: Episode #56, https://www.youtube.com/watch?v=HnuSOXhFELQ)
Tomas has been a short wave enthusiast since 1973, a ham operator since 1990, and is a United States Army Signal Corps veteran today. He launched the first civilian space weather propagation website, HFRadio.org, in the mid 90’s; HFradio later spawned SunSpotWatch.com; at press time Sunspotwatch.com is being revamped for the new Solar Cycle 25.
Tomas has contributed to the Space Weather Propagation column in CQ magazine for over 20 years, and for The Spectrum Monitor magazine since 2014. A product of the Pacific northwest, Tomas resides now in Fayetteville, Ohio.

Footnote: Yes, NW7US misspoke about the time it takes sunlight to travel from the Sun to the Earth. He meant that it takes sunlight and radio waves just over 8 minutes to make that trip…
Solar Cycle 25, and a Life-Changing Event (Part 1 of 2)
From the RAIN HamCast episode #56, 2021-XII-11 (used with permission):
When you were knee high to a grasshopper, did you undergo a game-changing experience that shaped your future career?
Here is text from the introduction:
Tomas Hood/NW7US did. Tomas has been a shortwave enthusiast since 1973. He was first licensed as a ham in 1990 at age 25.
In the mid 1990s Tomas launched the first civilian space weather propagation website, HFRadio.org, which later spawned SunSpotWatch.com. His website, NW7US has been up and running since June, 1999. Tomas has contributed to the Space Weather Propagation column in CQ magazine for over 20 years, and for The Spectrum Monitor magazine since 2014.
A product of the Pacific northwest, Tomas resides today in Fayetteville, OH. RAIN’s Hap Holly/KC9RP spoke with Tomas recently about Solar Cycle 25 and the game-changing afternoon Tomas experienced in 1973 at age 8 ( Read more about this, at his amateur radio and space weather blog: https://blog.NW7US.us/ ).
Here is the first part of the two-part interview:
Mentioned in the interview is Skylab:
From Wikipedia’s article on Skylab: Skylab was the first United States space station, launched by NASA, occupied for about 24 weeks between May 1973 and February 1974. It was operated by three separate three-astronaut crews: Skylab 2, Skylab 3, and Skylab 4. Major operations included an orbital workshop, a solar observatory, Earth observation, and hundreds of experiments.
Tomas was drawn into space weather as a life-long passion, by inspiration from Skylab, and from the hourly propagation bulletin from the radio station WWV.
WATCH FOR THE NEXT EPISODE, PART TWO
This video is only part one. The RAIN HamCast will conclude Hap’s conversation with Tomas in RAIN HamCast #57, scheduled for posting Christmas Day.
Hap Holly, of the infamous RAIN Report (RAIN = Radio Amateur Information Network), is now producing The RAIN HamCast. The results are both on https://therainreport.com and on the RAIN HamCast YouTube channel, https://www.youtube.com/channel/UCUbNkaUvX_lt5IiDkS9aS4g

The Lost Tribe, the Pied Piper and The Executive.
Think that the ARRL was the first amateur radio association in the United States? Or that the famous and brilliant inventor also “invented” amateur radio? If so, you are not alone. But pesky historical documents and the facts they contain tell a deeper and more accurate story. It’s in the October issue of The Spectrum Monitor. Smartly edited by Ken Reitz KS4ZR, TSM is a wonderful read in my household. I go back as a subscriber to TSM’s predecessor, the Monitoring Times, launched by Bob Groves, years ago. It’s a real honor for me to get the cover feature in the TSM this month. Thank you, Ken and Thomas K4SWL, for the encouragement on this revealing story!
