Wow Don, you sure have a full nav station. Here is what I did:
When I installed my C-80 radar/chartplotter, I located that unit in a Navpod at the wheel. I'm at the wheel 90% of the time I want to look at it anyway. Where you have your radar screen is where I have my communications center. I have a Standard Horizon Matrix VHF, the control head for the ICOM M802 and the external speaker all mounted on that "wall". The transceiver unit for the SSB is mounted inside the nav station seat, out of the way, but convienient enough that I can get to it if I need to for servicing. And it made running the cables and the copper foil to the ground VERY easy.
One of the reasons I liked the ICOM M802 was the separate control head from the transceiver. The footprint of the control head is about the same as a VHF radio, just not as deep. Makes for very easy and clean installations and the bulky transceiver can be stowed out of the way. Let me know if you want a picture, and I'll take my camera out this weekend and snap a photo for you.
Bill, the current costs for obtaining a restricted radio operator's license (RRO) is $60 and the station license is $160. To operate SSB anywhere and to operate a VHF in international waters (other than an emergency of course) the ship must be registered and there must be one person on board with an RRO. The ship's license is good for 10 years and the RRO is good for a lifetime.
I always tell people if you are going to put in an SSB radio, you should also think about getting a ham general license. Now that there is no code test, it is not that hard to obtain a general anymore. And there are a lot more ham's on the air than ships operating SSB. I was able to talk from my slip in the Los Angeles area to a ham in Argentina this weekend. Sure is nice to know the radio gets out and someone can hear when I really need it.
