[wsjt-devel] wsjt-x connectivity with Kenwood TM-V71 + RC-D710

[Paul B. <pf...@co...>]

Greetings--

I'm trying to get wjjt-x working on an old Windows XP box and my Kenwood
TM-V71 (+ RC-D710 upgrade) and having some issues.  On the Windows PC, I
have a USB-to-serial cable with the Prolific driver, and I know it
works, since I successfully run APRSISCE/32.

The RC-D710 purportedly gives all the same functionality as the TM-D710,
but I'm wondering whether there might be a subtle data port difference.
 On my rig, there's a data port on the back of the TM-V71, and another
on the back of the D710 control head.

What I've found is that the Kenwood memory programming software only
works if I use the data port on the back of the TM-V71.  But APRSISCE/32
works if I use the data port on the back of the D710 control head.

Now for WSJT-X -- I basically get no response if I use the data port on
the back of the control head.  But if I use the data port on the back of
the TM-V71 base unit, WSJT-X (when testing) can trigger the TX of the
radio, but doesn't appear to do anything else.

Is there a special driver needed for the RC-D710 port setup?  A bug in
the software?  Or should I be thinking about upgrading to the TM-D710?

Or perhaps I've set up something wrong -- should the rig be in Packet
mode or not?
