Speaking of conventional freqs, does anyone know of any talk-around or conventional 800mhz freqs built into the DTRS network?
I assume that they have the ICALL and ITAC freqs in the radios, but I wondered if the various agencies didn't have some talk-arounds of their own for local use.
Yesterday I heard several of the western radio techs heading down to the Telluride area. One of the units told another one that he would soon be out of "DTR" coverage area and that they should switch their radios over to "Zone 3" "Teleco channel" to keep in touch in the local area.
CSP units statewide have "CSP SPX" as a simplex, which I believe to be 868.81250
Other agencies in the metro area do have simplex channels as well, most for Fireground use, and some tactical. Most of these are licensed to the agencies locally, not statewide.
The only licenses that the state has for statewide simplex use are 868.81250, 868.62500, 853.48750 and 854.31250.
868.81250, among other things, is used for the Colorado Youth Offender System centers. They usually are analog, and have a DPL. One is in GJT at 360 28th Road, if you happen to be in the area, I'd be interested in knowing the DPL used.
853.48750 and 854.31250 are used for simplex telemetry in the metro area.
As for the "Zone 3" channel, the "Zone" they were referring to is likely the group of channels in the radio that the channel is located at.
Almost all agencies will have these channels in conventional analog:
I-CALL 866.01250 156.7
I-TAC 1 866.51250 156.7
I-TAC 2 867.01250 156.7
I-TAC 3 867.51250 156.7
I-TAC 4 868.01250 156.7
S-TAC 5 868.78750 156.7
