OK checking at the center pot terminal on the carrier balance control, my freq meter flickers between 8999 and 9000 khz. When I go to T then it flickers between 9000 and 9001 khz. I am not sure how accurate my meter is but it appears the 9 mhz signal is OK. In a message dated 3/31/2008 8:06:28 P.M. Eastern Daylight Time, [EMAIL PROTECTED] writes:
Garey Barrell <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Are you sure your Carrier Oscillator is on frequency? 9.00000 MHz. The filters are positioned on either side of that frequency and if it's NOT in the "middle" .... Also check the switching. You can clip a lead across each filter and then do an ohmmeter check through the switches. I just don't see that many "open" filters. Shape changes, increased attenuation, etc., but not that many that go completely open. Looking at the bottom of the transceiver, the "X" filter is the one to the right of the pair. Also, keep in mind that the filters are in effect in receive as well. Can you hear the calibrator in either sideband position?
