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.
I have been able to keep up with Doppler on AO-51 L/U by hand (while watching the computer prediction screen), so direct computer control isn't critical, but it seems like a good next step in station automation, if it's possible. The only interface I can imagine is to simulate mike up/down clicks through a parallel port. I am currently running a home-brew client for Predict under Linux, which spits out CAT strings to my Yaesu 736R via a serial port. So, mike-clicks will be a good bit of a re-write.
I guess the only other alternative is some sort of swap of 1271 for a 23cm Yaesu module... Any takers (or is this a bad idea)?

Yes, an 1271E TRX ...

... via "mike-click"-interface at the serial port. In between I have a serial switchbox to switch between CAT (Kenwood TS-711E) and the "mike-click"-interface. To receive in 70cm I have another serial port, totally 4.

Try also with switchboxes, USB-to-serial interfaces, serialport-card, and so on. But look, if the hardware will be supportet from the software.

Hi Thomas,
Ok, that's what I figured. Time to break out the C compiler and figure out how to twiddle the modem lines. Good to know that it can be done.
Thanks,

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...)

Hi Iain,
Well, that's the puzzle. I thought "all" ICOM rigs did CI-something, but the user guide never mentions it, and there's no so-marked connector on the back of the rig. The only thing close is an "Accessory Socket", but it only does stuff like squelch output, PTT switch, fixed AF output, ALC voltage, and some other analog stuff. Nothing related to the frequency setting.
Is there another connector (internal, perhaps?) which gives access to the digital settings?

For what it is worth my Icom w32a handheld has access to programming the memories via the headphone jack and a special programming cable.

Mmm, interesting idea. But, again, the 1271A manual mentions nothing. Thanks for the thought,

Ah....The UX-14 is(was) an internal CI-IV to CI-V converter board.
See http://www.icom.co.jp/manual/external/transceivers/UX-14.pdf
Lord only knows if either of the two connectors have a true parallel interface onboard...
...And the chances of finding a UX-14 these days...Although it does seem there are a couple of projects out there to create clones of the UX-14. Google would be your friend.

Hello Iain and Greg
With the externally CI-IV interface you need also the internally IC-EX309 interface unit. It has the centronics connector and 2 connectors to the TRX board.
