Re: [Drakelist] Drakelist Digest,Drake B line Twins No output
Well, the earlier problem with the spot frequency function not working has lead to no output at all from the transmitter. It shows idle current only when you go to tune or hold the PTT on the mic. Any ideas where to start. Tubes or power supply? Power supply rebuilt 3 or 4 years ago .After rebuilt it always had a 60 cycle hum on 40 meters. You could feel the cabinet vibrating.

Fred, >From previous threads, I suspicion not, but. In tune, does drive cause current to increase? Or in PTT, drive and whistle increase current? If so, look at the relay contacts. 73, Ron WD8SBB --- On Sun, 1/1/12, fjmel...@aol.com wrote: From: fjmel...@aol.com Subject: Re: [Drakelist] Drakelist Digest,Drake B line Twins No output To: drakelist@zerobeat.net Date: Sunday, January 1, 2012, 11:52 PM Well, the earlier problem with the spot frequency function not working has lead to no output at all from the transmitter.

Re: [Drakelist] Drakelist Digest,Drake B line Twins No output
Fred - All bands?? NOT a power supply problem. IF you key the transmitter can you hear it in a nearby receiver where it 'should' be? If you're set up for transceive with the R-4B, does it work in TRANSCEIVE under RCVR control? The power supply hum may be the result of transmitter bolts loosening. Some hum is normal, would NOT be related to a particular band(s). 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs fjmel...@aol.com wrote: /Well, the earlier problem with the spot frequency function not working has lead to no output at all from the transmitter.
