Does anyone know of a source of an extension cable for the 10 pin mini DIN data port on a Yaesu FTM-400XDR? I'm thinking of installing one in a location that will wind up behind interior trim once the install is done, so access to the radio will be difficult. I'd like to bring out the data port to a spot where I can plug in the CT-164 adapter cable to be able to connect a TNC or SignaLink USB modem or plug in the programming cable. Given the density of the pins on these connectors, I'm not overly fond of the prospect of having to solder one up myself and would really like to find a nice, ready made 15' cable.
