AO-51 Mode LS
by Matt 17 Sep '06

17 Sep '06

I had some luck with my AO-40 gear, MMDS downconverter - VK5EME preamp - 3' BBQ grill. But very limited comms. I am at a new location and my antennas and rotators weren't adjusted/calibrated enough for AO-51, and they were only installed last week. Got it sorted by Friday but az is still off by a couple of degrees. I kinda worked VK2RW Reg on the 13SEP06 @ 11:50z, but all we exchanged were call signs and the sat was at it's closest when I heard him/me. Then I lost it. By Friday and the weekend I was getting maybe 50 ~ 60% of the passes to my West, unlike my AO-40 days I have a lot of trees around me up to 30 degrees to my East and 15 degrees to my South. But it still was very tricky to work or find! SatPC32 couldn't get it right for the Doppler so I used my PCR1000 to find the downlink dialed in the 910 with the AFC on and i was ok from then. My uplink was a IC-T81a with a 16 Watt brick amp into 25 ele loop yagi with the memories set at 10 KHz intervals. So I think I was getting in ok I hope I didn't QRM anyone whilst trying. I have made some recordings of my downlink but it's only me calling CQ I forgot to record the QSO with Reg. With AO-40 it was easy to see how much error I had with my rotators and LO of my downconverter and so it made it easy to set up software like Satpc32 to accommodate for the difference. It's very hard to get it right will a LEO. I have started looking at S Band GEO sats so that I can remove all the errors in my setup. But all good ham fun I would like to see AO-51 in LS or VS more often in the future. Can AO-51 run LU? And what is the difference between DOVE's downlink and AO-51? DOVE seemed to be a lot stronger.

9-17-06 14:50 UTC pass of AO-51
by Kevin J. Smith 17 Sep '06

17 Sep '06

In FN00 I seemed to have the entire pass to myself. I did hear myself on a few occasions as I was sending out my call. I do have quite a few trees to contend with around my property so it is possible I could not hear others. I will be on the 9-18-06 00:25 UTC pass this evening. I hope to contact others as this will be my last opportunity to make an L/S contact before AO-51 switches to V/U. Thanks for the bandwidth. Kevin Smith N3HKQ FN00be

Symposium Pre-Registration Extended
by Emily Clarke 16 Sep '06

16 Sep '06

Since most (about 90%) of Symposium Registrations have been through the website we have made a decision to extend pre-registration through the 24th of September. We were able to do this because the production cycle for badges, etc. is now automated and requires very little human intervention except some minor paper handling! So if you haven't signed up now is your chance to get in at the last minute without having to pay the additional fee! 73, Emily Symposium Chair --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

Hey Joe, KM1P - Many thanks! I think this should do it. I think I have a leaky bypass capacitor that causing rf to get to the case. 73 - Joe, KS1I -----Original Message----- From: Joe Fitzgerald [mailto:jfitzgerald@alum.wpi.edu] Sent: Friday, September 15, 2006 5:11 PM To: Joe Kononchik Subject: Re: [amsat-bb] Astron SS-30M schematic needed Joe Kononchik wrote: > I was wondering if anyone had a schematic for the Astron SS-30M switching power supply. > Joe, Try ftp://bama.sbc.edu/downloads/astron/ss30/astron%20ss-30.pdf I think the only difference is that your supply has meters. -Joe KM1P
