My experience is with the CAT-300 controllers, but I have found that if the level to the DTMF decoder is set too high, it is a lot more prone to falsing and covering a transmission with the cover tone. I have found that female voices gave the most problem. Reducing the level to the DTMF decoder in the controller cleared this up for me.

This happens to one user more so than anyone else. Is there an adjustment? Why does this happen on only one of 3 idential controllers? Thanks. --------------------------------- Never miss a thing.
