At a whopping .3 w output you'll have to be REALLY close.
What radio lets you set it to .3w anyway?
This may have nothing to do with it but....
Over the years the police (basically) took over what used to be the FD TAC repeater on 502.1375 for their chit-chat channel. It has better coverage than the PD dispatch freq on 508.6375. FD used to use it in non-rptr mode on scene,
Just some FYI based on monitoring (and living in Media for 5yrs).
