[aprssig] Kenwood TH-D7AG Full Duplex?

The TH-D7AG will indeed do full duplex. I've used mine for satellite 
work quite often and it worked well, heading myself (on a headset or 
external speaker to prevent feedback) as well as the other parties on 
the satellite. You know the main shortcoming though, I hope. The battery 
you get is not the greatest and I recommend getting a spare from 
Batteries America (with the rapid charger they sell - no relations, just 
a satisfied customer). Nothing is more annoying when your battery dies 
in the middle of a satellite QSO...
Now you realize you'll also may want the programming cables, whether you 
make your own or buy them, still more money out of the kitty. The 
programming software is free though. OTOH, with the D7 you can do 
satellite/ISS APRS and it will also reflect your position on the 710, 
should you be going on a walk in the woods. So it will do much more than 
the old Icom, but at a price tag.
