Probably many of us have listened to something federal on analog. Be it 162.400-162.550 for weather. APCO P25 is quite popular. There is even some DMR. What other modes, if any, have you heard on federal VHF/UHF frequencies? Is there any NXDN? I was actually somewhat surprised to hear that there is DMR on some federal frequencies, because I thought APCO P25 was supposed to be the federal digital modulation standard for VHF and UHF.
