Default Re: Yaesu FT290

After a lot of poking and prodding... it seem there were two "spare" wires in the Mike lead. Thus I dont have to "Piggy back" the DC on the AF wire.
Apparently the FST button is there but has no function.... its not even mentioned in the I /B .
I am not going the RF compression route with this one..... however I will seriously look at it for my 2M SSB base station.
I attach the circuit I am going to use...the pcb fits into the old mike area.
The HARD part will be gaining access to the back of the Mike Connector, but a "faint heart never won a fair maiden" .
