I updated from the r35 to r57 firmware and received reports of an almost imperceptible but noticeable zizzy sound when I quit talking and before the vox drops out on 80M sideband. The listeners say it sounds like a fan in the background, but I have no fans or noise in the room. I reloaded the r35 and the issue was gone. Anybody have any ideas? Elecraft? Chuck, KE9UW
