I apologize in advance, if this subject is answered here already. Couldn't find one specifically. I have this issue with my TRX 1, and now with the 2. I am using the Moonraker pre-amp to bring in weak signals that are 30-45 miles away and I am doing pretty well with MOST conventional frequencies coming in strong, while others do not so well. With the preamp on, the scanner completely skips digital P25 completely, and brings in DMR with a greater signal bar of 4-5, but tends to skip DMR more easily. Can anyone explain what is going on, and can I correct this with a specific DCI filter for digital, etc? Thanks!
