Hello all, I updated the website and have all the telemetry information updated with equations where needed. I'm sure there will be more info I need to post. That will come as I get time. Ivan

ISS UK Pass 11.25utc
by David Barber 03 Aug '09

03 Aug '09

ISS system is keying up every 3 minutes as expected but no data transmitted, silent carrier only. Carrier remains keyed up for 30 seconds then drops. Signal is very strong suggesting a high power output is selected. David G8OQW

SAT PC H e e e lp!
by Jim Heck 03 Aug '09

03 Aug '09

Hi Folks, Wonder if anyone can help me? I am running SATPC ver 12.8 under Win XP. In the past I have had great success with controlling my radio (an ICOM 910H) but recently the control has stopped for no apparant reason. When I press the C+ button the radio goines into Sat mode OK, but the freq/modes dont change. I have stared and stared at the Doppler.SQF file, and cant see any error. I have double and triple checked things like CAT control baud rates etc etc. Can anyone suggest what else I should be checking? Its very stange as the radio goes into sat mode, but just doesnt seem to set to the correct freqs/modes. 73 Jim

FM repeater V/U Uplink 145.920 MHz FM Downlink 435.300 MHz FM FM 9k6 digital Downlink 435.150 MHz FM I uploaded the RX task for the SQRX receiver tonight and depending on the telemetry I get tomorrow morning, I expect to turn on the digital L band uplink on 1268.700 MHz. TXA (digital) power at 590 mW TXB (analog) power at 620 mW 73, Gould, WA4SXM for the AO-51 Command Team

Tubesat, a $4,000 launch opportunity
by Bruce Robertson 03 Aug '09

03 Aug '09

The first team that puts a linear transponder on board one of these, wins! (And I want William Leijenaar PE1RAH on my team ...) http://spacefellowship.com/2009/08/01/interorbital-syatems-tubesat-personal… Seriously, if this is for real, I think AMSAT should get at the front of the train and provide hardware, or hardware design, for those who plan to use it. 73, Bruce VE9QRP
