I just finished the restoration of my uncle's RCA Mark7 CB rig, vintage 1960. That's his QSL card in top. I heard stations from the west coast coming through yesterday afternoon.

Nice job!
Is that the one for which you needed the IF transformer? Open up the case on that puppy and let's see some good old fashioned hollow state.
ETA:
Don't know why I want one but a set of Demcos would be neat.

Demcos are way cool.Originally Posted by N8YX
Back in the day when radios and cars had style.
The one with the IF problem came from e bay Fred. I drilled out the rivet that holds the mica wafers together in the bottom of the IF. Then I took them out, reassembled the can, put it back on the chassis, and soldered the wires back on. Then I took a guess at the value and tacked a 120 PF cap across each coil lead. It receives, but not very well. I just have to find the right value caps to replace the micas.
I'll get a shot of the inners of unks radio when I make some room on the bench.
This is one I restored a few years ago. I converted it to 10 meters and it has a rock for 29.0 . Unfortunately there isn't anybody on 10 AM to talk to, so it doesn't get much use.

I'm QRV there quite a bit. Every time my TS-660 or one of the Paragon IIs is powered up, 29.0 AM (and 29.600 FM) is automatically scanned for signs of life. Those are the only rigs inline at the moment which are capable of 10M AM operation but I have a few more tucked away.
Problem between NJ and OH is...lack of propagation unless we get some sporadic E.

Yeah, too bad we aren't close enough for ground wave.
I enjoy the heck out of AM, even if I'm using a new fangled SDR. Recently, I've dropped down to 75 and 160 for a few AM QSOs here and there. Not running power, but it's working. Evenings on the low bands are getting much better. :)

Saw those. Going to keep an eye on the set and watch what the price does. The Super Satellite is the preferred one to have, though.
That DDS VFO idea is a thought ... it would make a nice addition to a 10M CB conversion project.

Good looking unit, George. You always do good work.
