SOURCE: 8 Pin Mini DIN Extension Cables (aka Yaesu Tuner Port)

[WB7X]

I needed to extend the control cable to my Yaesu FC-40 antenna tuner.

Found these straight through male to female 10' cables. Ordered 5 and they work fine between the FT-950 and FC-40.

ETA: Good info from Wiki:

Another option, I get the M-DIN 8 connectors for Yaesu cables from Jameco (they're also used for the data port on the FTM-350). They get $0.75/each for them.

Thanks Marty. Your solution is cheaper, but I've purchased the Yaesu CT-39 (http://hamradio.com/detail.cfm?pid=H0-002631) in the past for $10 when I needed a data connection. It comes with one end that goes to the radio.

Note that the CT-39A is a circular 6 pin mini DIN. Yaesu uses this for the majority of their dedicated packet interfaces.

The tuner port on the FC-20/30/40 is a circular 8-pin mini DIN and you don't use the CT-39A. This is the same as (or really is) the CAT port, so the CT-62 is the correct Yaesu cable. This is a lot more, about $30. It comes with a D-sub 9 on the other end.

What WB7X found used to be sold as serial extension cables for Apple computers for their printers and modems, which is a good source for pre-wired and/or molded connectors (and soldering to the miniature cups in mini DIN connectors can be infuriating, but I don't mind since I work with SMD devices).

The key with old serial cables is to find ones wired straight through and NOT a null modem or cross-over cable. But if you're just cutting the connectors off, then any old Apple serial cable will work and you can untwist the connections by beeping the cable out.
