Hi Greg,

?

With all respect, a healthy approach on these kind of problems should be “what am I doing wrong” instead of blaming the FT847 to fail, to be dumb or to pretend it wants to be smart.

In most cases, the people designing a transceiver like the FT-847 are smarter than you and me.

If you can't "fathom" why they would use a hand mike's audio for a rig keyed by a computer, that's normal - because they don't.

The purposes of the PKT and? DATA IN/OUT connectors are explained in the manual on pages 16 (AFSK) and 17 (FM packet).

The PKT connector is for FM ( not to be confused with VHF/UHF).

The DATA IN/OUT jack is for AFSK ( not to be confused with HF).

All digital AFSK software – no matter the frequency - ?goes via the DATA IN/OUT jack.

?

Also, the required resistor and the DC blocking capacitor are NOT there because of overload problems. They’re there in order to add PTT functionality via the same jack.

The easiest solution to solve all your DATA and PTT problems is to aquire a Yaesu SCU-17 interface.

All computer connectivity go via a single USB connector and the connections to the FT-847 go via a supplied RS232 DB9 cable (CAT) and a supplied 3 pin jack cable (audio and PTT).

Good luck,
