Re: No modulation on HF?

Correct.? The audio is "basically" gone, down probably 50+ db.? I was able to force a marginal FT-8 signal through from the back by moving it from a "Line Out" jack on the PC to the Speaker out, and cranking up the volume.? The radio survived doing this once, but I do NOT recommend this.

What you describe is definitely a problem, but it's in the design of the rig, not your particular copy.? All 847's behave this way.? To use FT-8 or Packet radio you need to key the rig via the same port the audio is coming in on (TRS for HF SSB, DIN for VHF/UHF FM), and NOT use CAT for keying / PTT.? The alternative is to use CAT for keying the rig, but wire your audio input into the Mike connector on the front.? You choose one method or the other.? You cannot do both (CAT for PTT, rear jacks for audio) with the 847.

Yes, but talking very loud you may get maybe 5w in SSB. In Fm (Hf only) or am, is barely audible. Carrier is good, 100W in Fm, but modulation almost gone. It works fine in vhf and uhf. Have 2 radios, same problem.
