My KX-1 is serial number 32. It was built this week and it is a lovely rig. I do have a problem with QSK thump. I am wondering if any of you have experienced this and I am interested in learning what you did to correct it.
It thumps when it goes from transmit to receive and the receive audio slowly comes back up to normal after about a half of second. It does not do it all the time, only after I have been sending for about a minute. Once it starts thumping, it will continue to thump until I cycle power. Sometimes that removes the thump, sometimes it doesn't. I have tried using three different antennas with and without an external tuner and nothing removes the QSK thump. I experience QSK thump on all bands. Any ideas? Thanks and 73 Jeff KB9ZUR _______________________________________________ Elecraft mailing list Post to: [email protected] http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post.
