What Spence said,

I would add that the 847 was built back when doing "data" communication on HF involved different "TNC" equipment than VHF, so (I presume) they designed it to segregate the various modes to different physical connectors on the back panel.? It is possible to wire things together with appropriate DC blocking caps and use a single sound card interface, but it's tricky.? Receive audio goes everywhere, but transmit only comes from whichever jack that triggered PTT.

Do note that using CAT to trigger PTT is a problem.? For reasons I cannot fathom, the rig listens to the front panel mike jack for transmit audio when PTT is triggered by CAT.?

Yes and WSPR and JT65HF.

? Also recently used on GreenCube but a lot of hassle due to GreenCube being simplex and the FT847 having to work doppler shifting and split on the same band. Very tricky to Doppler shift split frequencies going up and down.

? Apart from that, very good results with SignaLink SL-1 and homebrew interface.

? However, some issues with SCU-17 data port on FT847 cannot communicate with HF due to no data output in HF via data socket.

? Hope this helps.
