I think the IC-7100 is a ham radio
. The video is just showing up under the marine
page. Marine radios have the M in the number as in IC-M###. If you do a search for IC-7100 it shows a portable ham radio
with HF/VHF/UHF. Might be good for boat
use but not a marine radio. Hope that helps and I am reading it right.
From what i can tell on the site the only marine SSB
they still make is the 802. Too bad I think the 710 was their best but the 802 is a good radio too now that they have fixed some of the problems.
I see you have a Contest, I owned a Contest 25 for many years, nice boats.
