I'd like to design and build a CW keyer board to install in my IC-735 ...
last one I saw on ebay went for like $160 and I don't think I'm going to
pay that... :-)

Anybody know where I can get enough information on the interface to the
radio to do that, along with perhaps the right connectors to mate with
whatever the connections are in the radio?

Or, does anyone know of an aftermarket keyer board that's available for
something a bit more reasonable than $160?

Thanks...
