I have a MSR2000 repeater that transmits on 171.350mhz. We are seeing
a transmit spike at 157.072mhz. It is strong enough to break squelch
10+ blocks away with legible copy on the spike frequency. We
disconnected the PA and connected the duplexer directly to the exciter.
The spike seems to be coming from the exciter itself. Would anyone have
any suggestions on where to look on the exciter board to fix this short
of installing a notch filter between exciter & PA? I haven't yet
checked across the band for other spikes with a spectrum analyzer but I
fear there may be other spikes as well.
Thanks for the help!
Best Regards,
