[Kenwood] MFJ 1275

Thu Sep 14 18:00:09 EDT 2006

Ed,
I have the 1275 interfaced to my 870, but my manual to it has seemed to gone aloof.
So, I opened it up to look at the jumper settings.
Here goes:
HD1 Ground- jumper on #8
HD2 Mic ground- jumper on #7
HD3 Thru Pass- jumpers on #3,4,5,6,7, and 8
HD4 Audio from mic- jumper on #1
HD5 PTT to radio- jumper on #2
HD6 PTT from mic- jumper on #2
HD7 Audio to radio- jumper on #1
Jumpers 1 and 2 were both on. (front / center of the board)
My interface setup goes into the mic connector on the front of the radio.
Hope this helps!

Any one know the jumper settings for hooking up a MFJ 1275 with a Kenwood TS 
870?
Settings shown by MFJ don't work. MFJ has no one who knows anything about 
this interface.
