It is inter spacing white noise over the modulation like a second receiver open squelch being gated in and mixed, although there is none. I isolated down to the tx board by swapping every other module through another back plane/controller... process of elimination.. :-)
This station is a lightening strike recovery victim so all bets are off... :-) I suspected the dsp but a I swapped the system module with another known good one (two actuially) to no avail At 12:52 PM 6/21/2007, you wrote: >There are two pots in the TX SYN, but that would be a last ditch thing. >Usually you can make everything work OK in software.
