That's actually a major concern for me. I had an IC-7100 with the same problem. Could never get more than 30 watts on SSB (using a steady tone). Don't want to go down that road again. I'm sure the 7300 has enough juice to drive an amp, but I'm running barefoot. Two other things that concern me -only 1 antenna port, and only one key jack. If I upgrade rigs, I'd really like to find a radio that has two of each.
