Thanks. I think the RCA Phono for PTT and Amp key is a done deal. Although
Larry has stated no size concerns

My thinking is that potentially everyone would like to have an inexpensive
ptt and amp interface which protects the radio. Some may like to play with
the other pins so a much lighter header could be provided to make the other
open collector pins available with a light

I have never disagreed with the problems with the mini jacks. However, they
are readily available, small, come in different length patch cables, come
with rf suppression etc.
We could use RCA Phono jacks which have a lot of friction and are also
readily available. I
nest.

Larry has stated no size concerns, if we ignore size then we have the bulk
of a 15 pin through HD cable 6 ft long. That is heavy and is a monster on
the desk. The design should allow attachment

E^2,
I'll give it a runthrough and see what should be on a little board to
isolate the big bad world from the delicate innards
rigging a 15 pin connector as I did for the foot switch.

Thanks for the input, and I would definitely like to persue this as a

Folks
I think I blew the ULN 2003 open collector chip out of my
radio during the Belize DXpedition by trying to connect a relay in an amplifier
directly into the radio on x2-7 without any buffering. Perhaps a spike or
surge. Dunno. But it brings back to mind a project I suggested to
the amp control in one plugin.
