I recently got a Kenwood TM-D710G and have been experimenting with using its internal TNC connected to a serial port on my laptop for packet / PBBS operation. I can connect to PBBSes whose callsigns I know, and I can get the TNC to monitor (that is, print to the terminal) most traffic on the channel using the commands:

MONITOR ON
MALL ON
MCON ON
MCOM ON

However, I cannot seem to get the TNC to monitor the 'ID' packets sent by other packet systems. This is a problem when I go to other cities with packet systems on the air whose callsigns I don't know.

If I use the TRACE ON command, the TNC does show hex dumps of ID packets, such as the following one from station WU8C:

a2 a6 a8 40 40 40 e0 ae aa 70 86 40 40 65 03 cd 00 03 00 cc 07 04 00 01 ae aa 70 86 40 40 64 2c 66 30 08 00 00 00 00 00 00 00 2c 66 01 01

Granted, it is possible to decode these by hand (that one decodes to "QST WU8C..."), but it would be nice not to have to do so.

If anyone has any hints on how I might get the TNC to decode and display these packets, I'll be very grateful.

  • $\begingroup$ More info may be necessary. What terminal program are you using? What are its connection settings? Do you get any output at all with other combinations of commands? Does your radio's manual show any other settings related to this? What are those set to? What have you tried? $\endgroup$ – user157 Jul 2 '16 at 15:00
