After yet another careful cleaning of the band switch, my T4XB has now recovered and works as before. Thank you all for your help.

The problem was a dirty wiper of the XTALS switch. Cleaned with DEOXIT and all was well. 73, Stew K3ND _____ From: Steve Wedge < <mailto:[email protected]> [email protected]> To: Peter Ravn < <mailto:[email protected]> [email protected]>; <mailto:[email protected]> [email protected] Sent: Monday, August 26, 2013 10:36 AM Subject: Re: [Drakelist] T4XB tune problem Peter, you are probably outputting the IF frequency 5645 kHz (the carrier oscillator). That explains the strange setting of the RF TUNE and the high SWR on an 80m antenna. It could be that your band oscillator is not working. Do you get normal output on other bands?

From: Peter Ravn <mailto:[email protected]> Sent: Sunday, August 25, 2013 12:49 PM To: [email protected] Subject: [Drakelist] T4XB tune problem When my T4XB is in tune mode, and the gain control is fully CCW, the meter reads 0.4 A. Turning the gain control CW has no effect on the reading. The RF control is also out of control. When I want maximum peak on 40 meters, the RF control has to be turned to 80 meters. Output is app. 40 W and SWR is very bad. The plate control can be dipped but ends in a completely other position than the usual one. The problem is the same in SSB and CW, and when the T4XB runs as a separate transmitter. The bias is 0.07A. Any help will be appreciated. Thanks.
