Strange DPS frequency

twobytwo · #1 (**permalink**) 01-29-2012, 10:34 PM

While searching FCC website I found two "stealth" freqs for dps. The digital is licensed to be used itierant ULS License - Public Safety Pool, Conventional License - KA2686 - Texas, State of (DPS) - Frequencies Summary . The analog counterpart 158.73 is licensed statewide & not itierant so what is the difference in the two & what are they used for?

Probably executive security details. That is what the old 158.730 was used for. Things like governor escorts, VIP visits, etc.

I have to disagree with that. I have call letters as KEV491 for exec sec & 159.15 as the input freq.for 158.73 with 100 mobiles listed.I can not find a Repeater channel for 158.91 so it must be used only for mobiles .

One time about 15 years ago when I lived in Hurst I heard some mobiles on 158.91 PL 162.2 but don't know if it was DPS or not and I never heard anything on that frequency again that I thought might be DPS. There are a lot of other users.

There are some other frequencies they have like 159.075 that I have never heard used.

That was a pretty typical DPS tone, and the legacy still exists in the 162 NAC of CLE.

Its likely this is a low power VHF body mic used in narcotics investigations. Usually less than 1 watt simplex.

I doubt that they have 2150 body mics that put out 110 watts P25.

This freq (159.075) must be used for air to air/air to ground according to a post by Wayne on 5-7-11 under the thread DPS DATABASE CLEANUP
