Hi Ian, that’s a beautiful circuit and could only be improved by replacing the 2N2222 with a 4N33.

This is what have been using for the last 25 years with the FT-847 with various data modes in both SSB & FM including FT-8
Credit goes to ( I think) Jim Barber N7CXI who co-wrote W95SSTV which it was initially designed for.
Hope it helps
I've used my FT-847 on both 6 and 2M, no problem.? Just used the sample interface circuit in the manual.??

MAN, you guys are good !!!!..? Very obvious thing overlooked. HI.? All good now.? I had schematics out last night trying to figure out what components could be bad.? You made my day.? Any of you using something for FT8?? I had it receiving FT8 through the DATA IN/OUT plug but was trying to get transmit working.? I notice there was a claim that the DATA IN/OUT only worked on HF and I wanted it for 6 M. Probably have to go into mic jack for that and PTT.? Any units on the market that do that?? Have not looked.? 73 Mike K4PI
