[arm-allstar] REMOTE BASE W/ TM-V71A

Hi Kevin,
We've included hamlib with the hamvoip distro and it includes support for
about all the various Kenwood radios. See this webpage for more info about
hamlib: https://sourceforge.net/p/hamlib/wiki/Hamlib/
You can use the command-line tool "rigctl", which is an included
application to access the library. Doug has documented a method of using
the autopatch functions in app_rpt to conveniently send DTMF sequences to
any user script or program, including rigctl. See the how-to notes on the
https://hamvoip.org and specifically this page:
http://www.crompton.com/hamradio/BeagleBoneBlackAllstar/Allstar_extended_functions_using_autopatch.pdf
I have used the basic technique to control the G707, of which I have two.
I feel certain it'll work with the TM-V71A, which is very similar to the
D710, from an interface standpoint and is a later/upgraded version of the
G707.
In a future hamvoip release of AllStar, we'll have a significantly
improved method of interfacing hamlib or any other external applications
with app_rpt. More details about this will be announced at a future date.
Okay, now I'll change subjects to automagically getting the programming
data to the radio. I've got two of Jim's control boards which have been
previously referenced (See: http://ohnosec.org/drupal/node/162 ). I
haven't tried this board with any radio besides the G707, but I fully
expect it would work with the D710, TM-V71A and other radios with
the mini-DIN 6 pin connector.
Now, take a look at the schematic for this control board:
http://ohnosec.org/drupal/sites/default/files/9088.pdf
All the magic is happening in the CD4053 logic switch chip, which is
simplistically speaking just an electronic 3-pole-double-throw relay.
I won't go into a circuit analysis in this message, the operation is
simple, however, using a poorly documented but nifty feature found on the
6-pin mini-DIN plug. That feature is that the PTT (pin 3) and COS (pin 6)
signals serve dual purposes, based on the voltage (logic level) presented
to pin 5....Pin 5, when asserted, will change the operation of PTT (pin 3)
to TXD (TX data) and COS to RXD (RX data). So, instantly you can send
RS232 serial data for radio control at 9600bps! Pretty neat!
This all happens based on the logic level of the RS232 DTR signal from
the computer. When DTR is asserted, the radio flips to remote-control
mode. And, if not asserted, the radio is in normal mode, where PTT and COS
act as expected.
....If this doesn't make sense, I'll try to give a better analysis.

> Brett,
Thank you for the information… the next obvious question to me is, has
this been implemented in app_rpt? It would appear the Kenwood G707 has
been implemented, any thoughts where the file containing the commands are?

“…It is not the critic who counts; not the man who points out how the
strong man stumbles, or where the doer of deeds could have done them
better. The credit belongs to the man who is actually in the arena, whose
face is marred by dust and sweat and blood; who strives valiantly; who
errs, who comes short again and again, because there is no effort without
error and shortcoming; but who does actually strive to do the deeds; who
knows great enthusiasms, the great devotions; who spends himself in a
worthy cause; who at the best knows in the end the triumph of high
achievement, and who at the worst, if he fails, at least fails while
daring greatly, so that his place shall never be with those cold and
timid souls who neither know victory nor defeat...†-Theodore Roosevelt
