Can't filter what you also want to listen to. This was a frequency-agile remote base. There were some 2 meter repeaters on site as well & we accepted what interference there was when they were TXing, but the interference I'm referring to was without any of those repeaters TXing. In comparison, I also had a Kenwood TR-7950 remote base at a different location but having a similar RF view of the LA basin. Never heard a burst of IMD on any frequency it was set to in the 15 or so years it was in service. Filtering? None. >I'm having the same DCI not enough problem at one of our locations. At what frequency is it "not enough"? 151-152 MHz? Not much between there & 2 meters & very little below 2 meters until you get to ~137 MHz or so, so for most applications it should do the job.
