Jim, Hello there! Well, it's not in the operation of the rig, it's in the alignment of the ballanced modulator section. Using modern test gear I have good phase alignment up to the rf part of the chain. The rf phase C trimmer appears to work and the 12AT7 parameters and expected waveform is correct. The rf phase L trimmer does nothing and the corresponding 12AT7 parameters and waveform are not correct. I believe it might just be an imballance between the C & L trimmers but not really sure. That is as far as I got but have socket extenders to further test this. I suspect another silver mica cap problem but removing then replacing the modulator box has been near impossible due to my current bout with aggressive rheumatoid arthritus. I just can't put the rig on it's side to do anything further for now. It's a like new transmitter that I received in the original dry rotted box and probably saw little if any use. Due to my location a transmitter of controllable RF output is necessary untill I can determine if any of the nearby businesses are going to have an RF problem. This seems like the perfect one for this. BTW, will e-mail you off list about your use of the PTS signal sources.
Thanks, Bill, KB3DKS/1 ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
