.........I have one that had the same problem plus alot of digital noise. After not finding anything on the net, I removed the board and found cracked/broken solder joints at the volume slide control. After re-soldering them, the mic works like a new one. I wished I'd seen this thread much sooner..........let me know how it goes. 73s, Pluto.TonyV225 said:I have an echomax 2000 I have to scream into to get any audio element is fine.
