Default Narco com 11A help please

Hi All,
I bought the above radio on Ebay for the ultralight that I am building.
Anyway, I'm hoping that I didn't do anything dumb in choosing this older
radio. I didn't receive any pin out information from the guy that sold it to
me, and I'm assuming that he just plugged a newer set into the existing
frame and may not know how the radio is plumbed. The radio has two 15 pin
single sided connectors. Can anyone help me with pin out info? I went to
Narco's site, but the com 11A wasn't listed.
Thanks,
Jim Burns

The COM 120 pinout from that site will work -- same pinout as the 11A.

Funny you should ask about that radio because I have one I was about to
throw away. Being 320 channels, it is illegal to transmit on it, though
you can legally listen with it, so I understand from reading on a googled-up
avionics site.

The question I have is: Can you buy a legal 720-channel (or 760-channel)
Narco which will fit into the 11A's tray? How about it, some of you radio
guys?

You would think that after seven years the 360 channel radios being illegal
myth would die. The rule required radios to have a better than
0.003-percent frequency tolerance, it said nothing about channels. If you
don't fly in to an area that uses the new spacing of the 720/760 channel
radios, there is no reason to force an upgrade.

The 11B conforms to the 0.003 tolerance, the 11A can be made to conform and
the 120 was a pin compatible 720 channel replacement.

I'll leave it up to Jim Weir to explain the odds of getting caught with an
out of spec radio. :-)

If I pay the postage and a few bucks for the trouble, would you throw it my
way? The chapter needs a good hangar radio.
