I had been looking around for some time if someone had already managed to get I/Q data from Icom's IC-7610 HF transceiver without going through the binary-only hdsdr driver provided by Icom, but couldn't find anything.
First attempts at doing that on Debian Linux using libftdi1 didn't work, so I resorted to using the (again binary-only) libftd3xx driver from FT, and succeeded after some tinkering around.
The program here writes raw I/Q data to a file in int16-int16 format.
- Get libftd3xx from https://ftdichip.com/drivers/d3xx-drivers/
- IC-7610 I/Q port reference: https://www.icomjapan.com/support/manual/1792/
- The IC-7610 needs to be connected using a decent USB 3 cable, preferably without any hub in-between
- If the SuperSpeed-FIFO Bridge disappears after some time, re-plug the cable or power-cycle the transceiver
- Write to file:
./ic7610ftdi filename.cs16 - Send to TCP socket:
./ic7610ftdi host port
