GPS data for City Sanitation or anyone?

In SDRTrunk I have ignore data calls toggled off & 769.80625/770.30625/770.80625/771.48125 added. Should I be able to see the units mapped in SDRTrunk when they transmit (if I add another freq?), or it's not over P25 when dispatch is pinging & telling them 20s on the air, or they're only on the inputs around 799-801 (https://wireless2.fcc.gov/UlsApp/UlsSea ... c=16215588)?
I'm seeing phase 1 data channel grants but they don't seem associated with each sanitation voice TX, unless their GPS is beaconing at a set interval.
I'm going to try to set up the City's inputs as their own system & tune my other SDR to them & see if anyone maps.
ETA: Can't even get the LNA gain low enough to stop the Gain Overload flashing without crashing the second SDR out of the tuner list, forcing a restart to reacquire it.
