The Joomla site is up and running, but I am having trouble organizing the sections and categories and placing the articles in them. Need someone willing to explain and help document the processes so other content developers can contribute with limited knowledge, i.e the reason for CMS system. Please respond to wa4sxm @ amsat .org 73, Gould, WA4SXM

ARISSat-1 over Vietnam
by Vu Trong Thu 06 Aug '11

06 Aug '11

Hello everybody, I've just had my first try with ARISSat-1 this morning (max elevation 22 degrees), the CW2 signal is audible from AOS till LOS though the Morse Code Decoder had some trouble decoding the audio. Here's what I've got "ARIISATQ RS 1S NSPSI OET 327 M IH~30C CP +~3 C B~ 35N~TA IUHIS IEISSATL RST50E~VIET I5TS~UE+RT Q K", the rest is probably garbage as I tried to vary the LOCUT and HICUT of the SSB filter. I have a Kenwood TS-2000 transceiver, could anybody suggest optimal values for these settings? No BPSK frame was decoded, will try again! 73, Thu XV9AA

MacDoppler Help
by James Luhn 06 Aug '11

06 Aug '11

I saw the post by WA4SCA in regards to AMATEUR.TXT and ARISSAT-1. I am runningMacDoppler and I am such a newbie. Can someone tell me how to get MacDoppler to see the Keps for RADIOSCAF? I have downloaded keps from AMSAT and Celestrak. I can be such a slow learner. At least I am having fun without or without an antenna on the ARISSAT or even my home station. Thanks for any help! 73, James W5AOO

The launch went smoothly this morning though it was delayed by about three quarters of an hour due to a leak. Now we have to wait several years before Juno reaches Jupiter. 73s Bernhard VA6BMJ @ DO33FL

report of QRP ARISSAT-1 transponder operation
by Bruce Robertson 06 Aug '11

06 Aug '11

I thought the members of the list would be glad to read the following from Bob, WB4SON, written on the funcube list: "Guys I keep reading false rumors here about big-guns or high power needed to access ARISSAT. That is NOT correct. I had no issue hearing my signal on the downlink. I'm using omnidirectional low gain antennas (egg beaters) and 5 watts produced a S8 signal that was at least 5 S units above the noise. I have NO doubt 1 watt will produce a fine downlink signal What did or did not happen during the launch makes no difference now as it is working fantastically well Try it. Enjoy it. No worries!!!" 73, Bruce VE9QRP -- http://ve9qrp.blogspot.com

Arissat-1 Commanding?
by Burns Fisher 05 Aug '11

05 Aug '11

I saw on one of the NASA announcements that the snarffled 70cm antenna would mean no commanding of the bird. (This was probably before it was realized that that receive actually seems to work). But the question I have is whether there IS some commanding of the bird possible. I guess you have to be able to turn it off to satisfy the FCC (true?) but can other things be done? I assume/home that the command channel is encrypted, so disclosing its existance is not compromising the bird. 73, Burns W2BFJ
