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: [hidden email] http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post.

Update
I operated late last evening and the QSK thump stayed consistant all evening long. This morning, I turned the rig on and over a two hour period and two QSO's I did not experience any thump at all. I was using the same antenna as last evening and same external battery pack with a voltage of 10 volts. Maybe it healed itself! :) 73 Jeff KB9ZUR >From: "Jeff Imel" <[hidden email]> >To: <[hidden email]> >Subject: [Elecraft] QSK Thump on KX-1 >Date: Sun, 13 Jun 2004 15:14:07 -0500 > >My KX-1 is serial number 32.
