Using OTUSB & Xastir but NOT in KISS mode

Good day Groups,

I have been digging both groups before posting but i couldn't find the relevant informations i am looking for...

Before going further, is-it possible to run Xastir with the OTUSB but NOT in KISS mode? Not for iGating (for
the moment), but for basic messaging (mainly) and a bit of position report map plotting.

I know many Windows app are available, but i am doing my very best to stay with an OSX solution ;-)

Control Robot

My science club has built a robot that we want to control via APRS messages.  I forsee using our tracker3 to receive command through aprs message which would change the state of general input output pin.  The pin state would be moinetered by an arduino in order to execute motion commands.  Is it possible to to run scripts or control pin states.

Any advice would be apriciated

T3-Mini: Script & Monitoring Notification (Alarm)


a T3-Mini and the script editor, my goal would be to do a remote monitoring on doors and batteries cabinet (magnet contacts) with the analog or digital Inputs on the b oard.

If  a intrusion happen, an notification APRS message would be sent by the script.

It's possible to do?

 If we consider the limitation of the EXEC function described in the manual:

Execute T

Use this command carefully - the tracker's flash memory has a write endurance
of abo ut 100,000 cycles, and any command that changes a value in the tracker's
configuration will require a flash write.

thank you for help & info

tracker 3 and DR06T

Is anyone using the tracker3-135 with the 6 meter mobile for APRS ??? I intend to try it in the Elko,NV area as a digi and i-gate.   Brian  nb9e

T3-Mini power control?

Does the T3-Mini have an output available for power control?

I'm building a portable tracker (all in a box for a backpack) and the Mini is the perfect solution, if it can provide a switch output.

SMT Power Control External Relay

For use in an upcoming balloon flight I am planning to use the SMT open tracker (firmware 54817) to release the flight package from the balloon. I had previously successfully tested the power control external feature on the OT2m and would now like to transition to the smaller SMT configuration.


While I can configure the SMT with otwincfg and can control an external relay with the POWER command in  otwincfg, I cannot initiate the necessary ACCESS permission feature for remote command access.


I understand that I would need to revert to a terminal program and enter the call sign(s) permission in the AUTHLIST. I have used hyperterminal and putty , null modem cable , 4800 baud, 8N1 and have been unable to connect to the SMT except with otwincfg.


I would appreciate any advice on what I have missed in trying to connect a terminal program to the SMT.

Wanting to do aprs to the garmin nuvi 350

hello group

         I am kc9twx and new here. Wanted to know how to run aprs to the display of my garmin nuvi 350 from my baofeng ht?  I am not sure if this will all be plug and play or if it will be a long drawn out project here?

Restricting digipeating on T3

I have read the manual, and the answer to my question is not apparent to me.

I have searched here, but still uncertain.

What configuration options exist that would filter the traffic that a digipeater considers eligible for repeating?

Does the hop count affect elegibility, or does it only apply to packets that are repeated.

Is WIDE1 the only mechanism to configure a "fill-in" digi" or is it possible to configure the maximum used hops (eg non generic path entries with hasbeenrepeated flag) to filter packets for repeating?

I gather from the manual that there is no equivalent to -d/VK2RA*/VK2AMW* .

I did a traffic study, and we are looking at configuration options for one of the prominent digis to improve performance.

I have a OT-USB which was updated to the latest firmware a couple of months ago.

I can enter the command PWAUTH ON and it echos the new setting.

I cannot enter the SECRET command as described in the manual, the response is "invalid command".

Raw NEMA Trackers Leaking Positions into OT3m

So here is one hell of a weird bug! This has happened to me a few
times, but I haven't had the time to make it reproducible, and I
haven't even proven that it's the OT3m and not the i-gates, but here
it goes.

The APRS spec allows trackers to beacon their positions as raw NEMA
sentences instead of the ! or = posits, to allow as many brain-dead
trackers to out-live their usefulness as possible.  It would appear
that the OT3m sometimes processes these '$' APRS packets as having
come from the locally attached GPS when it receives it via the RF

Let that sink in for a moment. My tracker hears someone else's posit,
and then thinks that I am there, and beacons as such.

My most recent example of this was with W6MAF-3 yesterday on my drive
home from Death Valley. My path takes an odd jump down to Hesperia as
seen here: http://i.imgur.com/l9I7Nt8.png Right where W6MAF-3 is
tooling around town: http://i.imgur.com/wZZWkQu.png

Each of my fictional posits near W6MAF-3 happens a few seconds after
that station beacons in the exact same place:

The last time this happened was actually with Cap Pennell, KE6AFE,
which was particularly freaky since I thought my truck was in my
driveway while I was working on it remotely via RF cmd messages.

I don't yet have proof that this really is a problem with the OT3m and
not some digi or i-gate that's trying to parse messages and bungling
it, but it seems to be the most likely culprit.

Has anyone else seen this bug before? Scott might want to look over
the NEMA parsing code to check to see if you're using stale buffers?
