Sure. Just power up another radio and a TNC and fire up a terminal
program and watch what your T2 is sending while another station sends a
message to the T2. If you studied the "APRS spec" so you understood the
correct syntax, you could even send a message from that TNC to the T2.
:<callsign> :hello...{01
You might see something like this in your terminal program:
:VE7GDH-2 :hello...{01
VE7GDH-2>APOT21,SSI [07/14/2009 08:23:43]: <UI>:
:VE7GDH :ack01
The first line was typed into a terminal program with the TNC in
converse mode and with the MON ON in the TNC so I could see what was
being received. The colon makes it a message. VE7GDH-2 was that station
it was sent to. It happens to be using a T2-135.The second line is the
ACK coming back from the other station via the digi SSI. It was sent to
VE7GDH which was the station that originated the message.
If you don't have another TNC, just connect your T2 to a terminal
program and type "K" and hit enter to put it in converse mode and
proceed to send a message to yourself. Don't forge to turn MON ON so you
can see what if anything comes back. For it to work, you would need to
hear your message coming back from a digipeater... e.g. PATH WIDE2-1
should hopefully get you to the nearest WIDEn-N digi. If he digi hears
your message, and if you hear it coming back from the digi, your T2
should respond and try and send itself an ACK. It would look something
like the following.
:VE7GDH-2 :hello me...{05
<Digi Echo>
VE7GDH-2>APOT21,SSI*::VE7GDH-2 :hello me...{05
>From VE7GDH-2: hello me...
<Digi Echo>
VE7GDH-2>APOT21,SSI*::VE7GDH-2 :ack05
It's too bad you didn't give your callsign (and the SSID in your T2) so
we could have looked to see what your T2 was sending... including
message ACKs if they made it to an IGate.
Of course, you could just go to aprs.fi and look up the callsign in the
T2 and look at the raw data. Again, you would have to be making it to an
IGate for that to work.
