Sounds like you have t-r in the MENU set to 0.00, Paul. That makes the t/r delay zero so you hear the actual switching going on.
Try 0.01 or greater for smooth t/r switching. Ron AC7AC -----Original Message----- I am hesitant to put this question up here because I have seen so many posts about it but here goes anyway. I love my K2 sn 05834 except for one thing...the sidetone. There seems to be excessive thumps (clicks?) on both make and break, especially when using the internal speaker. I know there were alot of comments about the sine wave improvements, but has anyone been able to eleiminate or reduce significantly the thumps? _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
