J1, and gnd on the antenna tuner circuit board still elude me.

Many SEA tuners require just two things:
(1) a coax connection from the transceiver (in this case, the M700); and (2) a 12VDC connection. They will work with ANY transceiver.

I was just testing one yesterday, the second one I've had for some time. First one has been sold.

It would help to see a picture of the tuner you have to be sure exactly which model we're talking about here.

If you can't post one here, please email me a pic direct to:

try right clicking the image icon and "open image in new tab option" The Forum doesn't seem to allow direct insertion of images. perhaps this link will work

Section 3.2 mentions your RF connection is J1, looks like the shield connection is right next to it?

Here here Mike!!

He was able to determine that the ssb antenna input is the J1 terminal. I couldn't find that anywhere.

Excellent! what a fantastic resource the cruisers forum truly is.

Quick question:

will the newer AT 140 ICOM antenna tuner ICOM Tuner at West Marine work with an older m700 ICOM ssb?

Here's an answer to my own question:

the ICOM AT-130 ( https://www.google.com/shopping/prod...ed=0CFIQ8wIwAA ) is compatible with the ICOM M700s
