You seem to have over complicated the issue... In no particular order
try the following:
K3, no VOX, PTT - KEY both off. Line input only. DATA A.
From HRD, you should be seeing the K3 and displaying the frequency. Run
DM780 from within HRD.
HRD/DM780 keys the K3 via a serial command, you should be able to TX and
change back to RX OK. PSK31/RTTY/Olivia, etc. should be decoding OK on
DM780. TX audio should work OK into the line input of the K3.
It seems to work very easily for me, perhaps I've missed something that
others miss...
Call me on Skype (aon7800) and I'll talk you through the settings.

==================
The K3 dial frequency should be displayed on DM780 which runs via HRD.
DM780 should be
<SNIP>
I've run thru HRD's forums, this reflector, the Yahoo Group, and googled
the web. Nothing.
Here are my K3 settings:
VOX ON
VOX GN 50
AntiVOX 0
PTT - KEY RTS-OFF or any combination (tried'em all)
MIC BTN OFF (but ON does not work either)
MIC + LIN ON
MIC SEL RPL (rear panel)
on DM-780
Connected to HRD
I have a TX button set but it only puts the rig into the TX mode (no
power out)
PTT - none of the 3 options work
Shouldn't the cable I'm using between HRD and rig work to put PTT on the
line? And why won't VOX work? I've used both methods on other radios
with various interfaces.
