I recently installed a J&M system (found on EBay at a substantial savings) in order to talk with a buddy riding an Ultra. On our trip south this spring, the unit started to have problems with a creeping squelch level, first noticed as we encountered some wet weather. Now the unit is almost at the top of the scale, only needing a quarter turn from the highest setting to encounter noise. All of the connections have been checked, waterproofed with some di-electric grease and checked for ground shorts with a reliable multimeter. John Lazzeroni, President of J&M, says the BMW branded units didnt have the squelch control of the newer units. Anyone else experiencing a problem like this? It is quite maddening, considering the cost of the units, headsets and cords to make it work.
