TT$ config for Pat ax25?

Peter VE7PPE All Messages By This Member #891 Anybody have a working set of configs for using a TT4 with Debian linux SBC? Been working on this too long, when "everyone" says its plug and play. Reflashed V0.72 software, been through all the parameters a zillion times. Rechecked /etc/default/ax25 &/etc/ax25/axports.? Tried it on another laptop. #1 issue right now is that I can't get the TT4 to transmit from my IC-2300H. When I calibrate the TT4, it turns the PTT on, but otherwise doesn't.? JP8 is open, though tried both settings. Does the TT4 Kiss TNC need to be given commands from /etc/default/ax.25 like Restore, On, etc?? I thought that everything is set in the configuration, but could be wrong. I have ~40 years experience with computers, sysadmin/Ops, cli, AI, etc and find this very frustrating.? Got to be something simple. Any help would be much appreciated.
[email protected] All Messages By This Member #892 Peter, Could you amplify a bit on your application? For instance, if you are using the TT4 as a tracker, you must set PPeriod ( The rate at which it sends transmissions, default is zero) Generally, PPeriod is set at 120 (seconds) If you don't have a GPS plugged in that is generating a valid position report, it will not send a position report. You can disable the GPS validation by setting TOSV to FALSE, and it will send the default position somewhere around Madagascar I believe, otherwise, you need to manually enter your position.? 73, Allen AF6OF toggle quoted message Show quoted text -----Original Message----- From: Peter VE7PPE <ve7ppe@...> To: [email protected] Sent: Thu, Apr 1, 2021 5:45 pm Subject: [TinyTrak] TT$ config for Pat ax25?

Peter VE7PPE All Messages By This Member #894 Sorry about not explicitly stating how the TT4 was being used. I have been using it as a mobile TX/RX iGate and fill-in Digi when combined with APRX on a Pi W Zero.? Worked well. For the current application all I want is the Kiss TNC to use with Pat Winlink client on 2m.? Ideally I would set bank 0 to my APRS duties, and bank 1 to use for occasional 2m packet/Winlink. Do I need to initialize the Kiss TNC from my /etc/default/ax25 config?? Or is it all good to go once setup in TT4 config?
Peter VE7PPE All Messages By This Member #895 I'm receiving decoded packets, just can't get anything Tx. axlisten -cart shows both the receive and attempts to connect to VE7SEP-10, but pat connect times out without actually connecting.? Tx light does come on TT4, nor the 2300H.

Rob Giuliano All Messages By This Member #899 It sounds like you are able to get the TX and RX levels set using CALIBRATE and such, so the wirting to the radio appears to work. The issue must be in your AX.25 settings and I find them extremely frustrating. Since the TT4 is set in KISS mode and stays there through resets, etc. there are no needed configuration commands.? The issue must be in the axports, KISSPARMS and KISSATTACH, but I am not good with those. Do some research on thos parameters and ask on the groups that use AX.25 protocol more like PAT or maybe WinLink (not sure of apps though).

Peter VE7PPE All Messages By This Member #900 Like I said, it must be something simple $HBAUD 1200 --> 19200. I was lead to believe that HBAUD was the over-the-air baud, but that really makes no sense in retrospect because the TNC takes care of that. On the air and downloading my group.io emailed digests. I'm sure there will need to be some tweaking of the various ax25 parameters, but the basics are now working.
