Hi guys,
I'm restoring an old FT-847 damaged by lightning a lot of years ago and had been lying in the schack collecting dust, according to the previous owner.
After replacing the main CPU on the AF/CNTRL board the radio woke up from it's Cinderella sleep and the most things are ok now except the internal keyer.
I have also replaced the one-chip microprocessor MB8854-1244M which in fact is the keyer.
It is impossible to key the transmitter in CW-mode, nothing happens when I try.
I have run out of ideas and if someone has any suggestions please share them with me.
