I noticed a IC-M600 with a AT120 tuner on ebay.. Not much bidding activity
and current bid is pretty low. Item number: 2464392650

I'm wonder about opinions on this as a marine SSB? Any good? Better than
nothing? etc.

The tuner should be worth something. I know it is about half the size of the
SEA tuner I presently have..

I currently have an old SEA 223 w/tuner but haven't found room to mount
either because of their size..

Just curious.

thanks, that link was very encouraging.. I also found that the manual isn't
on IcomAmerica site but did find it on the World site, along with the manual
for AT120.

Now I will see how the bidding goes..
