Benrusselpa> The traffic you heard on Fire 9 the other day was for the St. paddy's day parade which was (I belive) in Springfield. My portable decodes MDC IDs, and according to the IDs, the radios were fireboard/delcom backup portables. I don't know what they were doing, but they would be the ones to use Channel 9 if anyone were going to.
JRM> FB dispatches the fire police by district. If they dispatch 11th district fire police, they don't want to hear 50-21, 69-21, 72-21, etc all responding on the radio. Granted, I think if they are being dispatched they should respond, but I don't make the county rules.
Septa> 46.08 hasn't been used since the county switched to UHF in 1995. In my area, FP use Fire 14. If fire ops switch to 14, they usually go to 13. Also, you heard Traffic 19 on fire 1 because it is technically a piece of fire apparatus. Why a "Traffic Unit" is acknowledged and the FP Captain in his POV is not, I'll never know.
