International satellite name

It struck me that i don't know why the callsign of arissat-1 is RS 01 S... "Radio Sputnik" and "Skafandr" I understand but why 01? While we are about it, although I don't wish to add to the names - RS01S, Skafandr-B, Arissat-1 - shouldn't she have an Oscar designator? May I propose MO-(number) - ie "Mezhdunarodno" (International) Oscar 73 de andy G0SFJ

ARR Preamp Help
by Zachary Beougher 07 Aug '11

07 Aug '11

Hi All, I was monitoring some passes while mobile today, and amidst all of the confusion of messing with coax and frequencies, I accidently transmitted on 440, through the preamp, with 35w (the relay is rated at 25w). I thought I had switched the VFO back to 2m, but I guess not. It was only for a split second, but since that every time I turn the preamp on it automatically knocks out all received signal. Does anyone have any idea on what I need to do/check to see what I did to it? I have heard of this happening, I just need to know what path to take now to get it fixed. It is worth mentioning that I can receive fine with the preamp in-line, but the minute I throw the power switch it knocks out all receive (just static, no received audio). I have not changed any of the connections, so having a coax hooked up backwards is not the issue. Thanks, Zack KD8KSN

Anyone using an FT-847 and SignaLink USB to copy ARISSat-1 BPSK telemetry?
by Alan P. Biddle 06 Aug '11

06 Aug '11

Hi, Has anyone used an FT-847 and SignaLink USB to copy, or attempt to copy, the BPSK telemetry? Reports of success or failure equally useful. In either case, it would be helpful to know approximately when the rig was made/purchased, due to the numerous running production mods. There have been a few reports of people being unable to "print" the BPSK telemetry, even though the signal is good, and the CW decodes well. Please reply off list. Alan WA4SCA

ARISSatTLM
by N0JY 06 Aug '11

06 Aug '11

I'm having trouble getting telemetry. ARISSatTLM will see the signal on the Tuning Indicator and I have tuned the CW signal everywhere from the yellow mark to the top and bottom of the blue range. It decodes the CW fine in the Morse Code Decoder window but nothing ever shows up in the Telemetry As Text or ARISSatTLM main window. The orange indicator is following something, usually hanging around the middle of the orange line range when there is a signal. Any thoughts? Windows Vista SP2 with M-Audio Delta44 sound card set for 48000Hz sample rate. Thanks!

Transponder
by Rsoifer＠aol.com 06 Aug '11

06 Aug '11

On the ARISSat-1 pass just ended here (23 degrees max elevation), results were about the same as yesterday. I heard my CW downlink for about a minute, peaking 559. Several other CW signals were in there, but I couldn't get their calls due to the deep fades. Bruce appears to be right that the transponder's performance depends largely on the spacecraft's orientation. 73 Ray W2RS
