Hello Alexander,
I have set my PATH to Others/ARISS. I see some have used ARISS,WIDEN-n
I just set UNPROTO CQ VIA ARISS. I've heard that the 'CQ' makes no difference; it works with or without the CQ.
I am a bit confused. What's the difference between:
"ARISS" vs "UNPROTO VIA ARISS"
Should they not both work?
My beacon is set again to TX 30 seconds AUTO.
When you beacon at a fixed interval it likely does not take into account whether the frequency is clear. You may or may not be colliding with the dozens of other users blasting a UI packet upward. Since its an FM channel the strongest signal arriving at the ISS captures their receiver. If you fit in between the other packets 5 watts usually gets through nicely.
It seems having an open squelch may cause the TNC to not transmit because it things the line is busy.
When I run with a hardware TNC I use CONVERS mode. I have a summary of the hardware TNC commands at: http://home.comcast.net/~k9jkm/ARISS_Packet_How_To/ ... but not sure how those map into your HT's setup.
Thank you very much. Question, it seems you are explicitly doing packet radio and not APRS (a derivative).
I also use AGWPE and UISS. The VIA [path] is selectable from a pulldown menu from which I select ARISS.
I think when I select PATH, I am to put in a string, I would assume ARISS and the my TNC will add the "VIA" part correct?
(which would answer my question above)
Also, to send a message via the ISS what is the address?
The ISS PBBS is RS0ISS-11. This requires a "hard connect" which is not recommended because over populated areas you will never to able to complete the QSO with all the other competing UI packets out there. RSOISS-11 is single user and when connected the full AX.25 protocol kicks in with the acks and retries, etc. We see ISS go over the horizon faithfully executing channel protocol and you will have not have been able to upload your greetings. Stations over the horizon will see the AX.25 disconnect message as it times out from your CONNECT request.
Again this is for full blown packet radio? I am just trying to use the APRS messaging service.
The crew is rarely at the keyboard so UI digipeating is your most likely path to success.
Right, got it.
Stations in less populated parts of the world connect to the RS0ISS-11 PBBS.
It does not seem to work too well over the USA from my experience.
I have been using RS0ISS-4 based on packets received.
VIA ARISS translates into RS0ISS-4 or RS0ISS-3 depending on the setup aboard the ISS.
For the RF side I run 5 watts into a 3-element 2 meter beam. The beam is fixed elevation around 20 degrees and turns on a TV rotor I got on ebay for $9.
Alright, so I again should address the message to 'ARISS' and not an explicit ISS address?
