Back on 145.800MHz at 1200bps over UK / Europe for the 13.05utc Pass. Confusing! David G8OQW

ISS at 145.800 (1k2) or 145.825 (9k6)
by Henk, PA3GUO 13 Dec '08

13 Dec '08

As David, G8OQW pointed out, ISS was now at 145.800 in 1200 baud. With a TS2000 one could easily monitor both freq's & speeds: 145.800 (ts2000/main + internal TNC at 1200) + 145.825 (ts2000/sub + external TNC at 9600) One radio, two channels. That should catch them all ! :-) Henk, PA3GUO

SSET via ISS (in 9k6): lot of fun to experiment !
by Henk, PA3GUO 13 Dec '08

13 Dec '08

SSET experiments - lot of fun with 9k6 APRS ! I have always seen APRS via satellites as a great way handle communication during emergency situation: - no 'what did you say, can please please repeat ? (digital comms) - no 'did I copy xyz correctly (no need to confirm the data) - no need to write down a message and then type it into email (all doen automatically) - not a single receiver but many (in the footprint of the satellite) - not only in the footprint, but via findu world-wide. live. - very efficient, if saying "we are all doing fine in xxx, no need for help" would take 10 seconds in SSB (voice), APRS can do this in <2 seconds. And now it can be done even faster: With ISS in 9k6 mode this is a good opportunity to test your station & skills: * set up your radio & antenna * connect any TNC and monitor 145.825 MHz * set your SW to autoforward what you hear to the internet (Igate) ... and test if you could send a Simulated Satellite Emergence Message yourself ! Radio: 145.825 (up & downlink) TNC: HBAUD 9600 U APRS VIA ARISS type for example :ALL :dummy text >> this will send 'dummy text' to ISS, and this will be on www.ariss.net within seconds ! type for example :EMAIL :pa3guo@amsat.org SSET via ISS, 9k6 experimental transmission >> this will send 'SSET via ISS, 9k6 experimental transmission' as normal email to pa3guo(a)amsat.org, within ~10 seonds seconds you will see many others these days experimenting, confirm their success: 00:01:40:17 : DL8DR]APRS,RS0ISS-5*,qAS,PA3GUO::Heard :PA3GUO-8,RS0ISS-5,EA2CNC,2E0EXL,EA7AHA,G8OQW,OE1VKW,ON6MU 00:01:42:36 : G8OQW]APRS,RS0ISS-5*,ARISS,qAS,DF9CP::BLNQSL1/1:RS0ISS-5,CT1DHM,PA3GUO-8,EA2CNC,EA7AHA,DF9EY,2E0EXL,DL8DR 00:01:41:35 : PA3GUO-8]APRS,RS0ISS-5*,qAS,PA3GUO::ALL :Experimental Radio Communication via ISS: 9k6 Packet Radio 00:01:43:43 : PA3GUO-8]APRS,RS0ISS-5*,qAS,PA3GUO::EMAIL :pa3guo@amsat.org SSET via ISS, 9k6 experimental transmission My setup: Kenwood TS2000 with its internal TNC running at 1200 baud + a PK96 cheap old TNC, externally at 9600 baud.

ISS UK Pass at 11.30utc. 1200bps Packet heard on 145.800MHz Missed copying the frames as my packet system was monitoring 145.825MHz for 9600bps. David G8OQW

Re: ISS 9K6 with ICOM 910

Alan (VE4YZ) said : ...short passes ...goode olde PacComm NB96 I'm reminded of a comment made by Nader (ST2NH) not so long ago, suggesting local testing between two of your radios to iron out kinks. It sounds like you already even have one side of that link up and runnable with your NB96 old-mode hardware... Thats a great start I'd think. Better than where I'll start with two (un-tested) soundcard solutions running back to back via two (un-tested) radios. (That probably explains why I haven't yet started) (The 9600 testing may well conclude, before I even get started ...) I wonder if my soundcard is good enough to record some downlink audio. Hummm, probably more of the same confusion/frustration. Good luck, be sure to let us know what works... 73 /;^) -- <- Licensed in 1976, WB5RMG = Alan Sieg * AMSAT#20554 -> <- http://www.somenet.net * http://wb5rmg.somenet.net -> <- http://www.linkedin.com/in/alansieg * My 'Day Job' ->

At least there are fewer stations than there were earlier. Apparently not enough, but at least the word IS getting around. Here are a few that did make it recently.

AMSAT DXpedition loaner gear project.
by Andrew Glasbrenner 12 Dec '08

12 Dec '08

The AMSAT Operations team is in the process of acquiring a few sets of basic loaner gear that will be available to DXpeditions and other groups in order to promote activity on the satellites. Initially these will consist of simple FM portable stations including a full duplex dual band HT and an Arrow or other suitable antenna. Depending on the success of the program, we will likely expand it to include the transponder and digital satellites as well. We also expect to be able to integrate AO-51 operations into the program. In the recent past, similar efforts have been undertaken by individuals within AMSAT, including W9AE's AO-40 package, and KO4MA's gear loaned to the KG4SB Gitmo operation. Thanks to the past generosity of AMSAT-OZ and a few individual donors to a prior personal effort to equip a Peruvian university station for AO-40, I have approximately 140 dollars to redirect to this project. To complete the first phase of this, I'd like to have on hand two split boom Arrow antennas with diplexers and two late model full duplex handhelds. The preferred rig is the Kenwood D-7 or Yaesu FT-530. These will be packaged together in two custom crush-proof PVC carrying tubes. We already have a major DXpedition to a location within LEO range of most of North America interested in participating in the early part of 2009. If businesses, organizations or individuals would like to assist in this program, please email me at ko4ma(a)amsat.org. All sponsors will receive full recognition from AMSAT for their participation. As indicated above, our major needs at this point are two split boom Arrow antennas with diplexers and two full duplex dual band HTs. 73 and thanks for your support of AMSAT, Drew KO4MA AMSAT-NA VP Operations
