Lately I've had my scanner on scanning a bank mostly comprised of EMS (CACC) frequencies. I also have a few MNR channels. I find I am hearing some OPP stuff on TGID 3904 (Halton MTO) and 2848 (MNR TAC 3). Is it possible that a few of the OPP TGs are patched with MTO/MNR? Can someone explain the idea of patching TGs together? I am guessing it just means that all transmissions on say OPS31 are also broadcast on other frequencies?
Thanks
