• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I see mounts on the vehicles for typical VHF-lo antennas but no whips are visible. The newer family of mil vehicle antennas look the same and cover 30-512MHz, so you have to look at the model to really tell.

Years ago in So. Cal I ran across several Army HUMVEEs at a restaurant and got a tour of the inside of one vehicle with a mounted SINCGARS radio and BK PRC-127 VHF handheld that seemed to be their convoy radio. I had a PRC-70 manpack (my favorite mil surplus ham radio at the time) with me but did not mention it to the Army guys.

Later in the day I ran across the same group in the mountains above Frazier Park, CA and yelled out the window "what frequency are you on!" and one guy flashed his hand with all five digits twice then twice again. I took that to mean 55.55MHz and dug out my PRC-70 and gave them a call.

To my surprise they answered and only said hi and gotta go or something similar but did acknowledge me. I would assume that is an extremely rare thing to happen considering their radio protocol but it gave me quite a thrill at the time.

Probably VHF low

I recall playing with a PRC-25, or maybe the (-70?, -77?, whichever model superseded the -25) at Luke AFB open houses in the past, and they went from 30-88MHz in 25 kHz steps. So they could be found pretty much anywhere in the VHF-Lowband, the old TV channels 2-4, the VHF-Midband, and TV channels 5 & 6. (As an aside, I wish more scanners covered the 54-88 MHz range in it's entirety. I understand some Uniden radios do cover the 72-76 MHz VHF-Midband.)
Also check the 14 ISR, or Intra-Squad Radio, channels in the 380-400 MHz range. (They're in the DB.) These radios are basically a military version of the FRS.
At one time, Icom manufactured an ISR radio model that was nearly identical to one of their FRS radio models, the only difference being the frequencies it used.

The PRC-25 and 77 covered 30 to 75.95MHz in 50KHz steps, fairly wide band FM and put out a couple of watts. The PRC-70 manpack covers 2 to 76MHz continuous, AM, FM and USB and up to about 35w output. That was quite an impressive radio being designed in the late 60"s released in 1974.

VHF lo SINCGARS radios cover 30 to 88MHz in 25KHz steps and it seems the new breed of VHF lo radios cover 30 to 106MHz but tactical radios seem to be going 30 to 512Mhz or beyond to 2GHz.
