I used a CT-16 with a pair of IC-706's to operate AO-40 on the
It works pretty well, although the 1200 baud speed introduces more
latency then is really comfortable. Obviously, doing this with a more
capable computer that would take care of Doppler too would be better.
And a higher speed unit would be good, but no one has done that, to my
knowledge. I think this would be easy to implement in a PIC, but what
do I know?
A combination unit, with a USB interface that looked like
either one or two serial interfaces to a connected computer, and could
function stand-alone like a CT-16 would be ideal, and substitute for a
Being able to change the configuration with push-push switches is
actually very nice and user-friendly, in my view, BTW.
BTW, a CT-16 doesn't require a CT-17 to operate. I always
disconnected the one to hook up the other, since I was also using one
of the IC-706's for HF operation, with a logging program hookup.

I'm not sure on the CT-16 or equivalent, but I do have a couple of
circuits I can share with you that will provide CI-V control from your PC. I
have not built any of these, but they look fairly straightforward:
I think you can use the MAX232 or two transistor interface.
I've also attached a schematic for another interface that someone else
shared with me as well.
I'd be curious to know if anyone is using two 706's autonomously with PC
control for sat work. I would also think you may be able to take two of the
aforementioned circuits or equivalent and be able to accomplish the same
Hope that helps.
