Hello, I am also just testing PSK on K3 with Microham keyer using Data A mode and get different results.. Fist think is if you proper adjust level from sound card that ALC meter show 4 bars and 5 flickering on 1500Hz means that every time when you change listen channel needs to re-adjust Mic gain to get good ALC level.. So, if you on highest freq. you will overdrive K3 but if you goes little down maybe you can not drive correctly K3 for require power... Please your opinion! 73, e72x - Gordan
