Hi, I have just started my peaberry V1.. The audio stage works as a sound card OK.. I have finished the receiver section and when I run HDSDR all I get is a loud hum which is centered on the frequency I am tuning.. I have tried injecting a signal but can't hear any thing but the hum.. any ideas are appreciated.. best 73 Ian VK5IS
