AI is at work on my Pixel 7 when stuff shows up on the phone like the town Coober Pedy.
Well, firstly Coober Pedy is the Opal Capital of the world and so that would put it in the middle of nowhere in downtown Australia.
At first, I thought it might be a CIA site like Pine Gap near Alice Springs, but it is not. Other notable info is that it is so hot there that many folks live underground in what is known as dugouts. They even boast dugout motels!

[Flash News: A friend in the CIA advises that CP is the home of Fred and Ethel of the AI duo. You heard it here 1st.]
There is a real issue in Coober Pedy because so many of the opal mines are shallow and located not too far underground. Many of these mine shafts pass right under the city. Thus, a high risk of sink holes
I grew up in Arnold, Pennsylvania and the same issue with the coal mines. One year a whole residential city block started to collapse into an old mine shaft.
But you tuned into this blog for radio stuff and so we look at another of my past projects which is a rebuilt Version 1, of the Shirt Pocket SSB Transceiver. The rebuilding was a result of an unfortunate accident were most of the original transceiver got smoked!
The heart of this rig is a 4 Pole Homebrew Crystal Filter at 4.9152MHz with the 2N3904/2N3906 Plessey Amp Module either side of the filter. The Balanced Modulator /Product Detector and the Rx/Tx Mixer stages are TUF-1's. The Mic Amp is a 2N3904 and the Audio Amp is a 2N3904 plus LM386. Another Plessey circuit is used as the Rx RF amp and Tx Pre-Driver. A 2N5109 is the Driver Stage and the IRF510 is the Final Amp.
Literally not much hardware but the "fun factor" is off the scale. The Shirt Pocket Transceiver was the subject of a QRP Quarterly article.
