Ok I can hepl6you here, when I get home next week, I will guide you through the repair. Check the circuits and find the AGC line, it will close to the IF output, follow it back to the RF amp. There

I would like to fix it myself, if not, I would like to send it to get fixed in the states. thank you

Adjusting rf gain makes no difference.

Quite agree this would be an improvement. I used a 4N25 optocoupler on my FT-100 interface (that has a slightly different configuration) and still use it today with the FT817 Built several of these

Hi Ian, that’s a beautiful circuit and could only be improved by replacing the 2N2222 with a 4N33. De Spence G5STO Sent while portable! please excuse typos.

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
