Graeme, if you need a few dB, there might be a few dB to get by
optimizing the RF system, tweaking sensitivity, using a better modem ,
looking at the antenna height, location on the mast etc.
I often think APRS digis should now be dual band 2m/70cm to reduce the
footprint of a APRS digi in a dense area. But that's another story.
However, I know I'll get about 9dB when the ginini TNC goes back up
.... maybe next week.
better radio sensitivity, radio on freq, better modem.... yes 9dB...
I've thought the coverage might go up too far.. as power will need to go
up, maybe 100W to match.
