[App_rpt] Kenwood TM-271

Hello Group:

Anybody out there interfaced a TM-271 (or 471) as a remote base with
app_rpt?

I had hoped that modern Kenwood mobile radios would share a common
programming protocol. The app_rpt mentions the TM-G707 as an example of a
radio that can be used with the rpt.conf option 'remote=kenwood'. However,
it does not work for me using the TM-271.

I built up a RS-232 to TTL interface which works fine with the Kenwood
programming software but not with app_rpt. Recalling a memory channel or
setting a VFO frequency results in an 'invalid frequency' callout from
Asterisk.

Looking through the app_rpt source function 'setkenwood', I see the string
'VMC 0,0' is sent to the radio initially. When I monitor the serial data
from Asterisk to the radio, this string is sent but the radio's response is
'?' (0x3F). One suspects this isn't the right answer.

Does anyone have experience or suggestions with the TM-217 on app_rpt?

I would be more then happy to sit down with you and your system on the other side of
a telephone conversation, and hack our way through it. When is good for you?

Jim:

Many thanks for a great offer.

I have found a non-authoritative list of TM-271 programming commands on the
web. I have hooked up minicom directly to the radio to verify them. As soon
as I have confidence that they are correct, I'll contact you.

I believe that the TM-G707 unit, currently supported in app_rpt, is no
longer in production. The TM-271 seems to be a popular RB radio, so support
for it in app_rpt would be welcomed by others, I'm sure.
