I'm experiencing no intermod because there is a single Decibel Products
cavity with two coupling loops in it in the antenna of each VHF radio, both
isolating the radio from out-of-band signals and providing direct-to-ground
lightning protection because the radio is no longer hooked to the antenna,
it's hooked to a coupling loop DC short inside the grounded cavity. The
cavity is simply tuned for max output power around halfway between 16 and
72 which passes both ends of the band adequately for recreational use. 25
watts in gives me 22 watts out on Ch 16, where it matters, and range to the
horizon doesn't suffer at all.

It would be nice if they'd put in a better front end to all the radios, but
they won't.

Lionheart has the M-602, which is silly but my captain liked the way it
looked next tot he M-802. M-502 is hundreds less money. You don't really
use direct keypad channel entry much..(c; Our M-602 panel buttons are
hardly ever touched...unless I'm listening to the talk on the boat we're
passing in a race to find out what they're trying to do to us. For radio,
the remote "Commander" mic turns the M-602 into an M-59 with simple
controls.

By the way, you MUST turn the M-602 on PRIOR to turning the remote
Commander mic on because the M-602 ignores the remote commands if it wasn't
booted up before the Commander started talking to it. The Commander will
come on and simply be ignored if it boots first. It's a bug, not a
feature.
