We have one - I just installed it on Beausoleil but haven't run a new coax up the mat, though, so I can't yet vouch on on how well it performs.
I do want to get a second handset/speaker combo. The transceiver's installed on a bulkhead in the salon
, and the handset's up in the cockpit
. When we re-do the nav station, we'll add one there.
Any specific questions? Other than how well does it work
? Yeah, I know - not very helpful...
