Hi All, I believe we now have some TLEs for ARISSAT-1 It is catalogue number 37772 and referred to as Radioskaf-b Approx 20 secs ahead of the space station at this time and appears to still be less than 1 kilometre below 73 Graham G3VZV

SDX on eclipse pass
by Masahiro Arai 05 Aug '11

05 Aug '11

I got my downlink signal on ARISSat-1 SDX at eclipse pass 1233-1240z 5th Aug. SDX was open at the same time CW, BPSK, FM transmitting at eclipse aka low power mode. I heard BPSK signal then QSY to SDX band. I got clear and laud my downlink though the elevation was less then 5deg. My uplink system is 10W with 13ele Yagi. Open time is 40sec every 2min. Very short but enough for quick QSO. 73 Masa JN1GKZ Tokyo Japan

Olá Piraja ! Operations •Three modes of operation •High – Everything 24/7 •Low – FM, 1kBPSK,CW with 50% duty cycle (2mn OFF, 50s ON) •Emergency – FM, 1kBPSK,CW @ 10 sec / 1 minute rate Operations •At launch, satellite will operate in high power mode for at least 2 hours •High power mode will be used as long as battery can support eclipse operation. •As battery deteriorates, low power mode will be used alternately with high power mode. •Near end of battery life, emergency power mode will be used to extend satellite operation as long as possible. http://www.arissat1.org/v3/index.php?option=com_content&view=article&id=73&… 73 de Roland PY4ZBZ

LOTW-Sats-AClog
by John Henderson N4NAB 05 Aug '11

Anyone help me figure out how to post a sat contact to LOTW from AcLOG; have spoken to both ARRL and AcLOG folks.... was like duh? ARRL is asking for fields that seem like duplicates to me, RX freq, RX Band....propagation mode, mode...and they are not available in AcLOG. Any help appreciated. May just stick with cards.

ARISSAT-1 question
by ps8rf Piraja 05 Aug '11

05 Aug '11

Hello All, I have a question about the transmission of voice and images of the ARISSAT-1. I had understood that he would send at intervals of 2 minutes an image and a voice message. But in the orbit over the Atlantic 11:38 UTC I was able to hear messages of greetings, reports of temperature, and SSTV without gaps between a message and SSTV. That's right, is correct !?. Thanks. 73 Pirajá PS8RF The Amateur Radio is supportive and helpful in any circumstance.

2-way SSB Contact on ARRISat
by John Papay 05 Aug '11

05 Aug '11

KD8CAO and K8YSE completed an unscheduled 2 way ssb qso on the ARRISat satellite this morning 5 August 2011 at 1125z. Signals were weak but readable. My keps were way off as the doppler shifted 1700 Hz from AOS till overhead elevation. If it had a uhf antenna, we would be doing a lot better, but whatever it has does work if you have big antennas. Using a KLM435-40cx and a KLM 2M-14C. Just amazing. 73, John K8YSE

Gould and Dee, It is with pleasure that I'm able to say I heard the the new ARISS1 at 0946Z (0246 local) from CN85mm. A solid copy but didn't last very long. I heard the lady's intro for about 20 seconds then gone. My first experience with the new satellite and only my 4th or 5 total contacts being so new. Congratulations Gould, Dee, AMSAT and all who worked on the project. 73 and take care Joe KT7E
