Just a few notes on the First system on the G5. I can receive the Anne Arundel cell eastward to about Chesapeake College. Westward, I can receive the Talbot cell in St. Claire.
I've reconfigured First on my G5 to conform to First zones, so all Zone 1 sites are configured to a single knob position, if that makes sense. I've split the G5 zones into regions: UES, LES, NCR, Central, Southern, Western. I'm loading the counties in their respective regions, and loading the appropriate First zone into that region, and programming the appropriate First TGs for the region.
I'm still experimenting with the optimal configuration for this radio, but the P2 upgrade works well with the First system.
