Last night at our second show of six, we had major RF issues. We run about 15 AT 7000 Series bodypack transmitters. (as a side note...if anybody has the frequency charting for these things...please send it to me....) They sell this in multiple bands and I cannot find a list of it anywhere...the one in the user manual doesn't specify what band it's for...??? (good on AT). The problem.... We had audio cut-outs with 3 bars of RF.... We had RF dropouts when the performers were standing center stage... we have to work with this gear... I've isolated what Antenna DA's don't work, and have eliminated 8 of our wireless due to bad DA's. I think the audio is dropping out with full RF due to squelch issues. HELP ME PLEASE! Today when I get there I will be setting all squelches back to full counterclockwise and starting over....please please please help me! I don't know what I can do to get rid of these RF issues.
