My K1 SN1730 has unfortunately learned a new trick.This radio was my first Elecraft kit many years agoand has been a rock solid reliable radio until a few days ago.I started getting a little squeal through the speaker on transmit and it quickly went away and the radio started acting like it's own transmitter wasoverloading the AGC and shutting down the receiver for a couple of secondsor longer. Sometimes requiring a restart on the on off switch to get it back. It happens on all 4 bands. The attenuator will sometimes reduce the effect, but not always. I had recently installed a new vfo pot (steel shaft) as well as the littleK6xx tuning board. Both seem to work quite well and appear not to be related to this.Looking at the schematic, maybe Q4?I'm hesitant to test this much with the key down to do signal tracing due to possibly damagingthe receive section.Suggestions? Don, Mike, Gary??ThanksBill MeredithKB5PNI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
