Satgen55 Join the Fun on 9600 17th April 90 Uosat3 Oscar 14 has been on this week as a 9600 FSK digipeater. Uplink is 145.975 MHz. Downlink 435.070 MHz, usually operating a 6 minute cycle. 4.5 mins slow, 1.5 mins 9600. But it can run longer periods of either speed Stations in DL, ON, G and GM are on 9600. You connect to them by sending, Eg c GM4IHJ v UOSAT3-1 How do you get aboard ? Satgen54 reported how to receive the 9600 downlink .It is a case of " Flying on instruments ". You use the centre tuning meter to check tuning, and signal strength meter to make sure you are tracking correctly .I also use the EYE DIAGRAM .I set my scope with sync from Rx Clock from modem TP8, and, picture from modem TP4. Scope settings are 50 microseconds/cm and 500 milliVolt/cm. Display is :- <><> , a pair of eyes or spectacles on slow speed , rounder than shown here. On 9600 the scope shows <><><><> . Four connected diamond shapes. Quality of reception is best when lines are firm ( not shaken by noise ), and the bottoms and tops of the diamonds are clear distinct lines , rather than jumble not quite coming together. Mistuning disturbs the symmetry and shape of the diamonds.For more detail see RUH modem notes. To access UO14 , I first tried 6 watts to a 5 el yagi from my old FT221R. No access. I next put this signal through a linear 40 watts . No access. Then at GM4JJJ's suggestion I made connections for my newer FT211 2m Tx and with no satellite present I sent key down unpro on the 211 Tx and monitored the eye diagram from the 221 Rx. It was awful. The bottomm half was noisy and bent back upwards to overlie the top half .I altered VR1 the RUH modem output. Even worse. So altered it the otherway and immediately got a good eye diagram with no overlap or noise. I set VR1 for best eye. I will check it later when I get an analyser and deviation meter .Next Uosat pass, I sent c gm4ihj v uosat3-1 , and got instant connect to myself. So I disconnect. I was just setting unpro for more tests when Roland DF3LZ connected. We exchanged locations and names ,then I forgot to tune my Rx , and lost it. So ended my first encounter with 2 way 9600 baud FSK packet. Meanwhile FO-20 came back on BBS on 12 April. Access was straight forward but on the last orbit I got hit by the disconnect bug and was reconnected against my wishes 3 times, eventually losing the bird before I could get off. Lusat is still digipeating, but Pacsat has had digipeater off and has gone to binary telemetry - which produces non ASCII rubbish on your sreen , but facilitates direct binary capture and decode with forthcoming AMSAT software. Weber is sending lots of pics. As suggested G3RUH / G3RWL I tried several 70 cm receivers and found one which copies Weber at quite low signal to noise. 73 de John GM4IHJ@GB7MAC
