Re: Wireless microphones
I think, if your signal is close to the recevier then it will dominates.
What I mean, I faced the same problem with my FM-TX which is at 87.7MHz, this channel is almost used but, when my signal is strong, I can hear my siganl within a 100meters range with building blocks in between. However, when the signal became weak, the other station dominates.
In brief, try to search for channel where no one is transmitting or transmitting with much noise, then ajust your TX frequency to this position and you'll hear your signal.
