How is the mixer going to enhance your audio?
Besides the output of a mixer will be a bit "hot" for a mike input. Yaesu uses dynamic mikes.

Posts are easier to read WHEN YOU STOP SHOUTING.

The DX626 seems to have a mic input preamp (XLR connector), and a MAIN OUTPUT.

Plug the mic into the XLR socket (there may be a switch to change from MIC to LINE input).    Adjust the preamp gain so you don't overload the preamp.

Run the MAIN OUTPUT to the FT-897 "DATA IN" rear-panel connector.  That wire should have RFI protection -- ferrite chokes might be enough.  A 1:1 transformer would be even better.

Connect a PTT switch from the DATA IN "PTT" pin to the GND pin.

Put the rig into "DATA" mode (see the instructions for "Packet operation" in the manual).

Adjust the MAIN gain control so that you get reasonable AGC action on voice peaks when you transmit.

That should get you started.

PS -- there's a page on Bob Heil's website that talks about connecting a Behringer mixer to a ham rig.  I don't think it's very good (he assumes you're using the MIC input to the rig), but for reference:

PPS -- if you have a PSK31 rig-to-computer interface (not something with its own soundcard), you can use that for voice.

ENHANCING AUDIO? GENERALLY IT'S ALL ABOUT ADDING MORE SHINY KNOBS.

Darn.  That explains why it didn't help me...mine had dull, satin-finish knobs.

Do you know where I can get a knob upgrade kit?

Take a picture and photoshop it. It'll look great on your QSL card  Cheesy

SHINY knob upgrade kit for Kenwood hybrids made (and now discontinued)  by K4EAA.

He also makes a kit to convert old Kenwood hybrids to all-upper case panel lettering.

The FT897 uses a 600 ohm microphone and The front jack is probably designed for about -60 dBm input.  The back jacks in the radio are designed around line levels, or about 0 dBm, and will be a closer match for your mixer.  But don't forget about supervision... the PTT that switches between transmit and receive.  Many in their haste forget to include it in their planning!
Good luck with the project!
