I am seeing about 1.7 or 1.8 v P-P across R77 when the gain is all the way up in transmit. In a message dated 3/31/2008 5:49:59 P.M. Eastern Daylight Time, [EMAIL PROTECTED] writes:
Garey Barrell <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Well, that's a problem! First thing comes to mind is that the Carrier oscillator isn't running, and you are tuning to the second harmonic of the PTO. On 20M you should have 9.000 MHz from the Car Osc. mixed with the PTO at say 5.200 MHz to produce a signal at 14.200 MHz. You need to see if the 9.000 MHz oscillator is running, on frequency and I would expect about 2V p-p across R77 at T13.
