Hi folks,
I'm pretty sure the answer is no, but I'll ask anyway...
Has anyone succeeded in interfacing an ICOM 1271A 23cm transceiver to a computer for Doppler control? 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...)
