our radios work just fine @KH
must be your location William. no problems here at the hospital, our radios are working fine (other than the usual craptacular audio we're used to). No one has had any problems all day according to my co-workers. Listening to CCFD on my XTS2500 in scan and it's fine. Scanners aren't perfect, you may have some local interference.
as far as Cobb fire coming out on the old 0920, I can confirm for the past few days the old dispatch talkgroup has been multi-selected, you can in fact, hear the dispatch side of all calls, no audio from the DTRS is coming through the old analog one, but it has been up as has the old Marietta fire simulcast on 154.25 (which RadioReference incorrectly has this listed as being licensed to Cobb county, according to the FCC it is the city of Marietta, and transmits from Fort Hill which is a CoM property, but what do we know right?)
The 154.25 is a cross band repeater connected to the old 800 analog TRS, so when CCFD mult-selects or patches the DTRS in, it becomes active.
I know they patch/multi-select when running mutual aid calls with Cherokee and Douglas who don't have digital 800 radios in their MCV's (yet) and for some reason, last I was in the 900 unit- no VHF radios at all (why not?).
