I used to hear a lot of them. Recently I only heard one. Now I don't hear that one, not even during our local music festival which is going on now.Some have gone to Nextel but a lot of stations still use the VHF and UHF radio links. Listen for traffic reporters at drive time and during live newscast and scan the media frequencies. You'll probably pick up at least a few.
I'm referring to the frequencies in the 450 Mhz range that they use to cue the on scene reporters and such.I assume you are talking about the frequencies they use for discussing news events and assignments, and not the frequencies they use for actually transmitting remote broadcasts.
They are probably not encrypted (like many public service systems are doing), but the fact the digital is not easily intercepted is most likely enough.Aren't the transmissions encrypted, I thought they were. Is it just a digital mode.
