ISS digi status



Hi,

The following unproto paths will work with the ISS TNC. I have determined 
this by experimentation, and confirmed it by sending numerous packets.

Set "Send" to "RS0ISS-11" via <nothing>
Returned packet from the ISS has the structure "RS0ISS,RS0ISS-1*,SGATE-11" 
(generated by the ISS TNC)

Setting SGATE-11 as an alias in forwarding ground stations should see these 
packets get to FINDU.

Send to "RS0ISS-1" or "RS0ISS-2" via <nothing>
Returned packet from the ISS has the form "RS0ISS, RS0ISS-1*"

Below are some examples record of the air:

ZL2TE has also tried this with success. We continue to experiment down 
here. I know that this is not how the ISS TNC is "supposed" to work, but 
this *IS* how it works at present. Setting your path this way means that 
your packets will be digipeated.

Using the recommended paths of APRS via RS0ISS-4,WIDE,SGATE  (or various 
variations) does not work..

Good luck

Examples...

Using RS0ISS-11
Tx Packet
Fm ZL2CIA To RS0ISS-11 <UI pid=F0 Len=20 >[14:45:19]
:FK8CA    :Hi there.
Rx Packet
Fm ZL2CIA To RS0ISS Via RS0ISS-1*,SGATE-11 <UI pid=F0 Len=20 >[14:45:22]
:FK8CA    :Hi there.

Using RS0ISS-1
Tx Packet
Fm ZL2CIA To RS0ISS-1 <UI pid=F0 Len=28 >[14:48:12]
:zl4ll    :You about John???
Rx Packet
Fm ZL2CIA To RS0ISS Via RS0ISS-1* <UI pid=F0 Len=28 >[14:48:15]
:zl4ll    :You about John???

Using RS0ISS-2
Tx Packet
Fm ZL2CIA To RS0ISS-2 <UI pid=F0 Len=18 >[14:45:55]
