I have done some searches for for the United States Federal Reserve Police Radio system. So far, I seem to run across 406.6625 mHz pretty consistently, but the mode seems to vary quite a bit from place to place. I have read posts of analog, but those all seem to be somewhat dates and I am pretty confident that most, if not all, have switched to a narrower bandwidth radio. However, I is still possible some areas remains with analog modulation. I have also read reports of both P25 and MOTO TRBO modulation. What is the latest on this agency? Is it likely that all are moving towards both common frequencies and modulation types, or are they likely to have each area do it own thing?
