I like to monitor some of the San Bernardino trunk sites with an 800 MHz yagi I have here in SE Los Angeles county. These sites are 50 to 60 miles or more away, but I have no real problem getting the control channel (CC) on several sites. The problem is the voice channels (VCs). I live in Radio Jungle Los Angeles and Orange County and Riverside County are in between, so there is 800 MHz activity up the wazoo.
The SBDO trunking system (TRS) is a Motorola II Smart Zone system, so the CC is obviously assigning the VCs. However, a few of the VCs are near other CCs or VCs of other systems, so when a particular talk group (TG) gets assigned to that VC, I hear a lot of buzzing, QRM, and crud. Locking out the TG is no good, because the next go around, that TG is likely to be assigned to another VC. So my question is can someone lock out a VC on a TRS.
I deleted the offending VCs in their respective trunk sites, but that means only that my scanner (536HP in this case) won't look at that frequency as a possible CC. But that does not prevent the SBDO TRS from assigning that VC, to which my scanner then automatically goes to (same principle as when using Unitrunker to control scanner.)
One can obviously lock out a frequency on a conventional system, and one can lock out TGs on a TRS. But is it possible to lock out a VC on a TRS such a scanner won't go to that frequency when the TRS assigns any TG to that VC frequency.
Any suggestions appreciated.
