Today: CBC Christmas Euroradio Special
Many thanks to SWLing Post reader, Fred, who writes:
Hi Thomas,
The CBC will be broadcasting their annual Christmas Euroradio Special December 20th throughout the day.
Merry Christmas to you and yours.
Thank you, Fred! I’ll “tune” my wi-fi radio to CBC Radio 2 and listen throughout the day today.
Looking for SWLing Post gear? We’ve got you covered!
Over the years, readers have often encouraged me to create SWLing Post shortwave radio-themed products, which is to say, t-shirts, coffee mugs, and the like. But for some reason, I’ve never gotten around to it.
That is, until now…

What finally motivated me to create these items is a friendship: I’m fortunate to number among my friends the amazingly talented Jeff Murray (K1NSS) of Dashtoons. It occurred to me that I might commission Jeff to design some shortwave radio-themed graphics that represent the broad spectrum of radio enthusiasts here on the SWLing Post. Jeff, ever enthusiastic where radio is concerned, was the perfect artist for the job–particularly since he and I see eye-to-eye on the beauty of both radio innovations and radio nostalgia. And with Jeff’s quirky sense of humor to enliven his sharp, dapper graphics, the great results you see here were simply inevitable.

Of course, his pictures speak louder than my words. As I’ve said, Jeff’s clearly a graphic artist par excellence, and it certainly doesn’t hurt that he really knows radio–inside and out.

While he was at it, Jeff created an SWLing Post logo that will soon accompany a refreshed Post design I’ve had in the works…stay tuned for that as the new year approaches.
In the meantime, I thought I’d share a link to a simple CafePress webstore I’ve put together for our newly-minted swag.
Click here to view great SWLing Post gear.
So far we only have a few select items on offer, but I’ll soon be adding more. But we do have two great t-shirt and coffee mug designs available now: the Radio Waterfall design features the SWLing Post logo superimposed over a blue SDR waterfall, with the words “DX FIEND” emblazoned beneath; the Radio Nostalgia design features the above vintage-style radio image, with”DX FIEND” beneath, and the “SECRET WORLD” image on the back. Take it from me, they look great.
Let me know if there’s something in the CafePress catalog you’d like to own featuring Jeff Murray’s terrific radio art, and I may be able to put it out there for you.
Oh, and by the way–a small percentage of your purchase (typically between $2.00-4.00US) goes towards keeping the SWLing Post online. The rest of the cost goes to CafePress’ product base price. True, I doubt we’ll ever sell enough to break even this way, but who cares…! After all, I do all this for fun, not profit.
Plus I confess to a little personal motivation: I really wanted a Jeff Murray-designed mug for my own cuppa joe!
The great thing about CafePress–although slightly pricey for some items–is that they offer great products, great customer service, and a no-questions-asked return policy. I like that.
So, if you take a leap of faith and purchase one of our items, please comment and let me know how you like it!
Side note: If you ever need amazing custom artwork for your QSL cards, your company, or your shack, I highly recommend Jeff Murray. He worked with me over the course of a week to nail down these incredible designs, and wowed me with his powerful creativity every step of the way. It was worth every single penny and more, and an honor to work with him, which is why I hope to have him create even more artwork next year! Thanks, Jeff!
And thanks to our Post readers for your purchase! Go ahead–join me in a hot cuppa!
Icom IC-R72: a repair story
In this post I’m going to tell you how I repaired my Icom IC-R72 receiver. Although it’s about a specific device, the logic and methodology applies to all radios.
I bought an Icom R72 from a friend for about $200. At first, I just checked 7.0MHZ (40 meter band) and 21.0MHZ (15 meter band) and it was OK. After some time, I tried to listen to some ham radio on 20 meters (14.0MHZ) and it was deaf! I checked everything: antenna connectors, balun…everything.
With some trial and error, I found out that it was deaf from 11-15 MHz. With the help of the members of “Icom R72” Yahoo Group, I found one of the usual suspects: bandpass filters’ switching diodes.
I took a look at the service manual and apparently this radio uses multiple bandpass filters for different frequency ranges.

As you see in the above picture (grabbed from service manual), one of the bandpass filters is for 11-15 MHz range–that’s the range where my radio was deaf.
Note that there are multiple ways to test that a radio is deaf at a frequency. One of the simplest ways: connect an antenna or even a long wire to the antenna socket of radio. The noise level should increase; if not, there’s a problem.

After testing diodes with a multimeter, I found out that D31 is faulty. Almost all multimeters have a diode-test functionality.
I replaced it. The original diode was 1SS53, but I used a 1N4148 which is very common and found everywhere. Now I have a working radio! 🙂
If you have a radio that’s deaf at a frequency range, there is probably a problem in bandpass filters.
Here are some internal pictures of my Icom IC-R72:

I should thank my friend and electronics mentor, Saeed (EP2LSH) who always helps me in my electronics adventures.

Fessenden Christmas Eve Commemorative Transmissions

This was reported in the ARRL Newsletter:
Brian Justin, WA1ZMS, will again put his 600 meter Experimental Station WG2XFQ on the air on for a Christmas Eve commemorative transmission. WG2XFQ will transmit on 486 kHz from Forest, Virginia, to mark the 109th anniversary of Reginald Fessenden’s first audio transmission. Historic accounts say Fessenden played the violin — or a recording — and read a brief Bible verse. It’s been reported that other radio experimenters and shipboard operators who heard Fessenden’s broadcast were astounded.
Justin will conduct a run-up to this year’s event starting at around mid-day Eastern Time on December 23. The “official” Christmas event will begin on December 24 at 0001 UTC (the evening of December 23 in US time zones) and will continue for at least 24 hours. Justin said he plans to repeat the commemorative transmissions on New Year’s Eve and on New Year’s Day.
Fessenden’s transmitter was an ac alternator, modulated by placing carbon microphones in series with the antenna feed line. Justin’s homebuilt station is slightly more modern, based on a 1921 vacuum tube master oscillator power amplifier (MOPA) design. Listener reports are appreciated and may be sent directly to Brian Justin, WA1ZMS, at his QRZ.com address. (Brian Justin, WA1ZMS, built this replica circa-1920 transmitter, capable of CW and Heising modulated AM. Photo by Brian Justin)
While I have not heard Brian’s transmission before, I have actually heard a transmission on the experimental frequencies between 465 – 515 kHz. I never expected to be able to hear anything due to extremely high local noise, but one night the propagation gods smiled upon me and the evening was exceptionally quiet. I listened on my Elad SDR receiver over and over to the Morse Code signal which was extremely weak, but mostly readable. I confirmed with Multipsk software, verifying I was indeed hearing one of the experimental stations out of Connecticut.
For information regarding the 500 KC experimental project you can follow this link.
Why not give a listen? You just might be surprised like I was to hear something on this band, and you could add a little Christmas Eve radio memory to your collection!! 73, Robert
