Re: Computer control of ICOM 1271A?



Sorry for the slow response, but:

In preparation for the ISS L-band uplink, I maybe have barely enough uplink power to get in, but it will need to be right at mid-point on an overhead pass.  That's when Doppler shift is the worst.

IIRC the Icom *71 series used the CI-IV interface (Later models such as
the 75 series used the more well known CI-V interface)

CI-IV was a parallel interface, and Icom did do a (probably expensive)
CI-IV to CI-V converter, which was probably not much more than a TTL
Parallel-Serial converter

Since I know the CI-V interface is so well documented, hopefully the
CI-IV was as well (was before my time...)
