Hi All,
I have a K2/100 feeding a KPA100 in an EC2 case. I have a foot switch and cw paddle connected to the key socket at the rear of the K2. I have a problem with the tx/rx switching. When on cw the tx / rx switching works just fine, but when on SSB and I press the footswitch OR key the paddle OR the PTT switch on the mic socket , the K2 switches into tx mode OK but when I release Ptt switch (any of the three ) the rig returns to rx but the received volume is severely attenuated. Only careful listening confirms that it is actually receiving. I can resolve the issue by repeatedly pressing the PTT switch (any of them) many times or (oddly) by pressing certain buttons on the K2 eg Mode , band, Pre amp, or even turning the power control up or down so it switches the KPA in or out . Not all buttons clear the issue but most do. I have no idea where to start looking for the fault and I would be very grateful for any suggestions of what this might be. I have a suspicion it may be an Aux Bus issue. I don't think it is a sticky relay as the eventual return to full receive is not accompanied by a relay click and anyway I think the entire tx/rx switching is solid state. Any help or suggestions please. Replies direct to me if possible , please. Thanks in advance ! 73, Vic GW4JUN K21926 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
