The IC-7300, IC-9700, and IC-905 all do SSB, but they cover different frequency bands and at different power levels.Oh, it was my understanding that they all did SSB?
IC-7300: Covers HF frequencies in the 160 to 6 meter bands, 100 watts output
IC-9700: Covers VHF/UHF frequencies in the 2 meter, 70 centimeter, and 23 centimeter bands at 100, 75, and 10 watts respectively
IC-905: Covers VHF/UHF frequencies in the 2m, 70cm, 23cm, 13cm, and 6cm bands (3cm optional) at power output ranging from 10 to 2 watts depending on band
My gut feeling is that while 2m and 70cm may be useful in Alaska, most activity on those bands would be on FM and you can buy radios that covers those bands in FM mode with more power at a lower price than the IC-905.
