Hi,
I use my paddle as ptt switch when in ssb which gives less noise
than a switch on the mike.

Well, maybe NOT! There is a pinout (I believe it's the 8R line,
if I
recall) which is normally used for driving externally-keyed
devices, such as amps and other similar devices. I suspect the 8R
line will work for you as well. This is, I believe) the line that
Elecraft uses with their KPA100 100W amp to provide drive to a
HEXFET output to key external QRO amps, so it should be pretty
easy to access and use.

I believe it keys several mS prior to RF appearing at the output
of the K2, so this should allow your remote devices to switch
first.

ASK on the reflector... I'm sure there are those who have
accomplished this.
