Balázs notes that in the season nine finale, he spotted the previously mentioned HT-32 (see image below), in addition to the iconic Panasonic RF-2200 (see image above).

Honestly, I think both of these radios would serve you well in a post-apocalyptic world!
Turns out, The Walking Dead is filmed in Senoia, and Fayetteville, Georgia, USA and SWLing Post contributor, Steve Yothment, lives nearby. As the then president of his radio club, he was consulted last year about radio gear to use on The Walking Dead set. He tells us to look out for an HF amplifier and field strength meter in future episodes! How cool is that?!
Many thanks to SWLing Post contributor, Steve Yothment, who writes:
[Below, you’ll find] my reception report for the digital decode of the Fldigi message by Dr. Kim Elliott on The Mighty KBC (6040 kHz) Saturday night:
I took Kim Elliott’s suggestion and listened to The Mighty KBC on 6095 kHz on Sunday morning using the Utwente WebSDR which receives signals in Enschede, in the Netherlands.
The Mighty KBC finished their last broadcast on 6095 kHz at 11:00AM our time. I recorded their program, but the file is big. So, attached is the last 4 minutes of their program (click here to download), as received by the WebSDR:
It’s too bad that The Mighty KBC is shutting down!
Many thanks for both your decoded message and your recorded audio, Steve! I agree: it is too bad the KBC had to shut down their 6095 kHz broadcast.
“Yes, modern radios usually have a micro communicating with the DSP IC through I2C communications.
The inter-IC communications includes a clock and data line. The clock for I2C is typically 400 kHz nowadays. Harmonics from this clock line are probably the source of the interference.
The manufacturer should have designed the product to ensure that this interference does not occur. It may be that they resolved it at one time but with limited manufacturing quality and component substitutions that often occur in mass production, the problem is occurring now even though it may have looked OK earlier in development. At least, that is my experience with such things. (I used to design car radios for the Panasonic Company.)
Many thanks for your comments, Steve! I recall a similar metronomic sound on another DSP-based radio, but can’t remember which model. I need to dig through my reviews as I’m sure I noted this. I believe checking 400, 800 and 1600 kHz will become a standard checklist item when I review DSP-based radios.

“I received an “audio QSL” card from STF Radio International a few days ago. Have you heard about it? [The QSL] actually has grooves on the card that you can play on a phonograph. I had a friend play the audio on his phonograph and he converted the audio to MP3 format. Then, I decoded the digital info in the file.”
Steve decoded the digital data from the audio QSL card and documented the contents on a PDF document. Click here to download.
Steve: this is brilliant! Thank you not only for sharing the QSL card images, but for the audio and your excellent documentation of the digital decode!
Readers: What’s the most interesting QSL card you’ve ever received?
