I use the W2ENY interface and have never had any problems with it, but they
can be built quite easily if you have the time. When I first needed it, I
didn't have the time to look for the parts or build it, so I found this one
and it works fine and is a LOT cheaper than the Icom interface. I did a
Goggle search for "icon amplifier interface" and came up with plans for some
showing schematics and parts required, so it wouldn't be much of a problem
to build one even if you felt uncomfortable with your own design.

I haev no interest in Bob's financial future but I use several of his items
and am very happy with them and have never had any problems with any of
them. They do as advertised.
