The TS-130S seems to work when powered by my Astron power supply. There's something odd going on though. The heat sink on the back of the radio gets warm even when ithe radio is turned off. This could be a big project.
There's no power coming from the power supply so that will be at least one more project.
Conveniently, a schematic showing how everything is connected is attached to the base plate.
The back of the microphone head comes off with four screws. Mmmm, look at that delicious foam rot. Will probably have to get a new microphone element. Those connections are pretty ugly looking thanks to the rotting foam.
Base plate comes off after removing 3 screws. Terminal strip, amplifier circuit, volume control, and a very dead 9V battery. Looks pretty stock to me.
I don't have any radios that use a 4-pin connector, so I can't use it yet until I get around to making an adapter. In the meantime, thought I'd see what it was like inside.
Got the balun rebuilt and it seems to be working properly. Still needs weather proofing, but I"ll do that if it ends up living outside more permanently.
An Atlas 210X 5 band HF rig mounted in a 220-CS AC console. Sounds like it works but I need to connect it to a proper antenna. Haven't looked inside the radio yet.
This news makes me very sad
RIP Mr Trebek
A couple more x-rays of my HP 28S. 80 kV, 2 mAs. The higher energy shows some more detail through the circular object.
Thanks to a friend of mine for reminding me that the HP 28S can beep, so the large circular thing would be a piezo buzzer.
