I own a Kenwood TM-D710E.
I connected it via the COM-connector on the panel to a Raspberry pi. On the panel I selected "packet12" (with the TNC button). After that, I can send TNC commands to the device using minicom.
Next step: I enter "KISS ON" and "RESTART" in minicom to activate KISS mode on the Kenwood.
After that I run /usr/sbin/kissattach -l /dev/ttyUSB1 ax0 on the Raspberry.
If I now enter axlisten -t -a and send packets using an other system (baofeng + tnc-pi), I can indeed see those packets via the Kenwood!
The problem now is sending. If I do:
beacon -s ax0 'this is a test - PD9FVH'
then the panel shows for a fraction of a second 'STA' but the Kenwood does not transmit anything - I verified this by listening on that frequency using the Baofeng.
Note that in "audio mode" everything works both ways. I can hear myself via the Baofeng and via the Kenwood.
The power supply can deliver 25A.
My question now is: Does anyone know why the Kenwood won't send?
