This odd DIN footprint seems to be a JA-radio thing.  The Kenwood 930/940 series has this same, "unique" arrangement for its XVERTER jack.  In my HF-centric world, this jack is where one can tap into the receive path for Beverage antenna use.  I guess that's better than not having any jack for this purpose.

Excuse the ASCII "art"

"U" arrangement (940/930/1000MP/etc.)

 P       P
P    P    P
X         X

"C" arrangement (everyone else!)

 P       P
P    P    P
 X       X

Notice the two pins marked "X" are closer together on the "standard" 8-pin; all others are spaced the same between connectors.  If you don't need the signals on these pins, cut them off the plug and you'll be OK. 

If you do what I did and insert the wrong plug into the jack, you'll likely (as I did) crack the jack on the radio.  Fortunately, in my case, the jack still functions correctly.

PeoplePC:  It's for people. And it's just smart.
