>Can you show some pictures of the oscillator? The wiring is point-to-point, so I don't think a picture is going to tell you much.
>Is there a tunable inductor in the oscillator circuit? As I mentioned, nothing tunable there. >Who makes the unit? It is an LPB RC-6A carrier current AM transmitter. It was used at the local university many years ago. I was told they used to have several. I am rescuing it from oblivion. I get a nice, clean 5.5 W carrier and the 2nd/3rd harmonics are well within spec for this type of transmitter. (No, I haven't broadcast with it. It is on a dummy load.) >The FCC specification for AM broadcast transmitters is +/- 20 Hz. Yes, I understand that is the rule for Part 73 (is that the correct number?). I'm not sure it is as tight for carrier current, which is under Part 15. I don't see anything in Part 15 about this. I'm just going by some old information found on the internet. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
