[chirp_users] No Download from Kenwood TM-D700a

[mark at marwalk.com]

Dan, you identified the problem for me. I had the radio in TNC PKT mode,
looked up in the manual how to take it out of that mode and Chirp promptly
populated. It did click my Flex PTT, but as you said, that was momentary
with no ill effect. I was already using the cable I got from BlueMax49ers
made for the TM-D700 so I was fairly sure it was terminated properly for
that radio. I'd even talked by phone with Mark there, who told me about
having to use the legacy Chirp for this radio and that's what's working for
me.

It helps to know what questions to ask, and it's too bad the how-to
documentation is not better than it is. I really appreciate your time.

Thanks!

fine.

Right, but the physical connection isn't enough - the port on the D700 is
not wired like a normal serial device intended to connect to a PC, which is
the problem.

> One thing I observed was when I entered the Radio Download menu it keyed
my Flex 6600; there's no reason for that as the Flex doesn't have that COM
port in its CAT list. I've shut down the Flex and all other apps and
rebooted the computer with the TM-D700 on and the FTDI cable connected at
both ends. This time the Radio Download action in Chirp resulted in the fan
coming on for about 2 minutes on the TM-D700, and then still no results on
the screen.

The act of scanning the ports on the system may cause the DTR pin to assert,
which can cause some radios (i.e your Flex) to go into transmit mode.
However, it should be brief.

If the fan comes on on your D700, you're probably also making it transmit,
which probably means it's in TNC mode or something.

After my last message, I pulled out my D700 and confirmed that it is indeed
a gender changer needed to talk to a DCE serial port (i.e. on your PC), not
a null modem. The radio has a male port wired DTE, which is not normal for a
peripheral. So your cable, unless it's intentionally wired wrong for a D700,
is probably expecting another DCE device (i.e. has a NULL modem in it for
talking to another computer). But, if it really is wired for the strange
configuration on the D700, then you need to make sure your radio is ready
for serial communication (i.e TNC and KISS disabled, etc).

> Could you tell me how to generate a debug log? I've enabled Developer mode
but that menu is still grayed out even after restarting Chirp.

The first thing you should do is disable developer mode and restart.
Developer mode is intended for developers, not users, and you should not be
running in that mode.

Next, reproduce the issue and capture the log. Instructions are here:

https://chirp.danplanet.com/projects/chirp/wiki/How_to_report_issues

I'm not sure what "that menu is still grayed out" refers to, but it's not
anything related to the debug log, that I know of.

Please do *not* send the debug log to the thousands of people on this list
and instead open an issue per the instructions above and I'll at least let
you know what the log indicates, if anything. My D700 just now connected and
downloaded immediately without any problem, so I think CHIRP is likely not
the culprit here.
