Hello I recently got a DM32 to listen to my local counties Fire dispatch and EMS dispatch cause Im in EMS and nerd for this type of stuff and want to know whats going on. Anyways, my county got a structure fire recently and wanted to listen in on the Fire Tac channel but couldnt. I have an understanding of the CTC and CTCSS tones but I looked up the Fire Tac channel it listed and DPL 251 tone. I looked it up and it seems DPL is just Motorolas term for a DCS tone so it should be interchangeable right? I did see inverted vs normal tones but do I need to input a different tone into CPS for me to be able to listen in?
