Well its about time and I suppose these units have served me well.
I purchased a set of M20's from RadarRoy in Spring 2006 and they've come in handy many times. When I turn on the jammers they squeel (normal for the start up period) but they continue to squeel. Sometimes they stop squeeling and sometimes never. I disconnected one and the problem stopped but now the other is doing it. Anyways here are my questions:
1. Is there a quick easy fix I can do?
2. Its been 4 years any warranty or repair?
3. Would the control unit work with then new m27's? And could I buy those separately?
Thanks for the help and support through the years
