I have many scanners, all fed from my EDA-2800 8 port amp. My BCt-15X's are clear and no noise, my PSR-410 however always has squelch fuzz with the voice whenever a milair comm comes in? It's fine for other conventional freqs like 154-174 but Milair 220-400 always has fuzz? Anyone else have this problem or a fix for it? Maybe I'll try external speaker?
