RCA Radio Model RC Operation

This RC radio is among one of the first products marketed by RCA in and about 1921. Westinghouse produced this RC radio for RCA. It is a battery set and uses three 01A vacuum tubes. The circuit is Edwin Howard Armstrong first major discovery, the regenerative circuit patented in 1914.

Do you, by any chance, have a picture or diagram of how the insides are wired? I know stuff is loose in mine, and I don't want to try to power it up till I know that it's wired right.

@TN048

No I do not have a wiring diagram, but I'll look for one. I did another video on the RC called - RCA Radiola RC Radio 1921-22 - it has some close up picture of the insides. My audio transformers are not original to the set. But the picture may still help.

I also have one of these model RC radios! I've not been successful in getting it to work, however - all I get is static. Did you have to replace capacitors to get yours to work?

[AllAmericanFiveRadio]

@jonrsawyer

Does it regen? I did add a capacitor but I don't remember how much it improved its reception.

[jonrsawyer]

@AllAmericanFiveRadio: By "regen" I think you mean the audible feedback in your video when you turn the tickler up high. No, my radio doesn't do that, even with the tickler setting at maximum. Any suggestions?

@jonrsawyer

Its the RF that is feed back. Check all the coils and connections. Then with power on and the filaments on check the plate voltage of each tube.

[jonrsawyer]

Never mind! I just needed a longer antenna, it seems. I posted my own video of my radio working.

I sent you a YouTube email

I just received my Dad's old RC from a friend who says it is in great condition. So .... I have lots of questions after seeing your video. What speaker and batteries did you use? Are you in the Tampa area?

Doing good thanks.
