Howdy.? First off, I'm a vintage radio tech.. tubes (valves?) are my favorite things to work on.

However, I have a friend & neighbor that has an FT-847 that he asked me to take a look at.

Here's what I found as far as symptoms:

?

1. No AM at all. No TX, no RX, no reaction to PTT. Dead silent.
2. Radio is deaf on all bands. Zero receive. There is static but broadcasting a +3db signal in my shack (via my HP 8656B generator on each of the modes the radio can do, zero signal detected. At +3db, neighbors a block away should pick it up.)
3. No TX on any band or mode except FM.
? 3.a. TX function is activated with PTT however, there is no modulation in any mode.
? ? ? ?(This was verified both via the supplied microphone as well as injecting an audio signal into the mic jack)

? 3.b. FM appears to have full power (I saw 40 watts on the meter.. I didn't check to see if this was a menu setting or just max for FM.)
4. CW mode checked. (plugged in a straight key I use on other radios).. Internal keyer functions and moves radio into TX however, no power from finals.

I did do the master CPU reset (held <FAST> and <LOCK> while powering up the unit. No change to listed symptoms.

?

This is really about the extent of my testing ability with the equipment I have.? So here are two questions:

?

1. Do any or all of these symptoms sound familiar to anyone here?

2. Recommendations for someone qualified to dig into this radio?? I got ripped off on an Icom repair by an alleged radio tech some years ago and I'm pretty gun-shy when it comes to sending a radio to someone so solid recommendations are appreciated.

?

Thanks all!
