The sidetone works, but beyond my cw note, you will hear a whistle or other note .... This whistle disappears if I delete ANTIVOX cable, and listening to me through the R4C my note is always pure and clean in the air. So it's a local problem sidetone. I tried to replace the 12AX7 and 6ev7 that are part of the circuit sidetone, vox etc.. etc., but I did not get any change. Some amateur has had similar problems? many thanks _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
