[FADCA] Lake Panasoffkee Site

 I presume you have checked the polyphaser to see if its still good?
also  has anyone checked to see if the acuall popcorn is coming from the
digital side by monotering both freqs and compairing . i have ran digital
and voice on the same antenna 2 meter voice and 440 packet at the same time
with no interferiance to speak of
 siginal is leaking in somewere and in most cases its a bad power supply .
not sure if the repeater is the same as that was in the basement of the
courthouse  master pro
 and not sure what the didital equiptment is
 the tower came from the deland area and no new hardware was used to install
it .
 check all grounds with a meter to be sure one isnt contaminating the rest
by leaking
  try these and see
 turn off digital for a few minutes and keep the voice repeater runnnig
solid with chartter and see if the noise is ther then turn it back on while
they are chatting and see if noise returns. is the noise on a constant time
like every time the repeater is keyed up or worste at differant times?
 I sometimes have on a scanner here and have not noticd any thing out of the
normal during the id
 could the deviation have gotten to high and its clipping
 the signal or could something in the id section be getting coroded
 hoe my rambeling helps
