thanks for all the responses…
to answer Ray’s questions, the antenna on the receiver is about 8-12″, thus an older VHF model. and also, only one antenna on the receiver. guess that’s two strikes!
we ended up purchasing a Sennheiser system, the ew100 G2. i used this for an audio only recording at a two day conference in a hotel conference room of aprox. 700 sq feet (total of 12 people in attendance, basically a pretty small room). the first day went terrific, i used my new sennheiser system on the “primary” presenter, and the customer supplied Lectrosonics on the “secondary” presenter. no problems at all! the second day, about 4 hours into the session, i started to get a lot of “staticky hits” from the Sennheiser system, so i changed the batteries on the transmitter and still had the problem. i had the two presenters switch systems and everything went okay after that, except then i had to “ride” the fader on the mixer for the channel that the sennnheiser was on. what do you guys think caused this? did something on or near the same frequency get turned on nearby? should i have tried changing channels on the Sennheiser? also, what exactly does the “pilot” function on the Sennheiser’s do? i had it “on” on both transmitter and receiver during the recording and could see on the display of the receiver that it was switching back and forth between pilot I and II. Any help much appreciated, thanks!
