AO-51 L band frq
by Luc Leblanc 26 Mar '10

26 Mar '10

I was able to find some time yesterday to repair my L band DEM linear always the same issues with the N type connector solder tab on the board who break if the coax is putting some stress on the center pin. I heard someone on AO-51 this morning just at the end of the pass (i don't get his call sign) who told me the L band uplink was 5 to 6 KC up the listed frequency? It could explain why i always have to tuned higher than my PC corrected doppler uplink frequency on L band. Aside of this signals where great aside of the constant background noise probably some kind of radar as reported in the past. At the first over the Atlantic pass the noise was not there it starts when AO-51 was approaching the continent.

Hi Mike, Yes I means, of course, the caos when everybody are making experiment everywhere on the satellites transponder over qso, ecc .... All experiment are useful and interesting when they are done properly and educated, I agree 100%. 73" Frank IW4DVZ -----Messaggio originale----- Da: Mike Rupprecht [mailto:mail@mike-rupprecht.de] Inviato: venerdì 26 marzo 2010 10.52 A: 'Francesco Grappi'; amsat-bb(a)amsat.org Oggetto: AW: [amsat-bb] I: Re: [eu-amsat] RE:New digital mode ROS - Satellites ? Hi Frank, Yes, you are right - we have enough chaos on our FM satellites !!! Believe me, I'm one of the fighters for more discipline. Maybe I understand our hobby a little different. Amateur Radio is for me an experimental hobby. I find it exciting to do new things and learn from it. Digital modes are equal to the analog ones. If I do an experiment at the outer end of the band, the risk of disturbing others seems to be very low. And if you carefully look at the spectrum ( http://www.dk3wn.info/p/?p=13368 ) during this experiment - you will see that no other station was not even close. The bandwidth of the FO-29 transponder is 100 KHz. There's room for everybody. 73, Mike DK3WN -----Ursprüngliche Nachricht----- Von: amsat-bb-bounces(a)amsat.org [mailto:amsat-bb-bounces@amsat.org] Im Auftrag von Francesco Grappi Gesendet: Freitag, 26.

Yes, there will be an AMSAT booth at the 2010 Rochester (NY) Hamfest (i.e. "Atlantic Division Conv.") I will be running it again as I have for the past 9 years. 73, Richard, N2SPI

*Hi all, Was wondering if AMSAT is going to be @ the Atlantic Division Conv. (June 5;Saturday)(In Rochester,NY)? The reason I ask is, I know that I won't be @ "Dayton Hamvention" but want to go back to Rochester after a long absense! 73,.Stu (WA2BSS) PS Will more than likly will take Amtrak to Rochester from Poughkeepsie,NY (Home of both the Queen City of the Hudson Valley/"Walkway over the Hudson") *
