In case you’re curious, that four tone chirp your MotoTRBO radio emits as a talk permit tone is G6, C6, G6, E6; that’s 1569, 1046, 1569, 1317 hz. Each tone sounds for 40mSec with no silence between.
I’d heard that you can customize it on Hytera DMR radios, so if you want them to all sound alike, there you go.
