Olmsted County is on the ARMER (allied radio matrix for emergency response) system. This system is a APCO P25 standard. to be able to listen to this system you need a digital scanner. The system frequency is 853.6125. TGID's are: FD Dsip (20476) FD OP 2 (20472) FD OP 3 (20482) Mayo Clnc (20492) Med Update (20434) Med Air (20020) OLM PTAC 1 (20550) OLM ATAC 1 (20402) Airport 1 (20448) LE Disp (20506). Those are the tgid's i primary listen to, they are the same as "zone a" in a fire dept. radio.
Thank you fwfdengine2, now I just need to figure out how to program my new scanner. I have the Uniden BC346XT and it's not the easiest thing to program. Not sure what you mean by TGID'S but will try to figure it out. Thanks again for your help
unfortunately, you are not going to have any luck receiving ARMER with a 246, since it is not capable of digital modulation. You will need a digital scanner in order to receive digital transmissions in Olmsted County, Dodge County and Goodhue County.
mmtsc, its 346 not 246. prob a typo err. but he/she still cannot monitor armer with what they have now. i would suggest BCD396XT I was just in rochester the other day and it works great. and always has statewide for armer.
about the only analog VHF in Rochester is LEC 2, Mayo One helicopter and Gold Cross EMS, which are listed in the database. Mayo Clinic also operates their own trunked radio system, which you CAN listen to and hear Mayo security operations and the internal downtown EMS response team. there also may be a UHF station link for Rochester fire, but i have never listened for it.
