Antenna question
by Jacob Tennant 05 Mar '15

05 Mar '15

A buddy of mine has given me a Cushcraft A270-10S dual-band antenna. I was going to try to use it start my satellite antenna farm and was thinking of mounting it on a rotator, angled at 45 degrees up from the horizon and angled at 45 degrees polarization. The main reason for the high up angle is that I live in a bit of a valley or as I call it a hole. North and South aren't to bad as I have heard passes at about 20 degrees, to the east my horizon is about 25 to30 degrees. To the west though I have a horizon of 40 degrees. So I was thinking wit the antenna pointed at 45 degrees above the horizon would give me the best chance all around. Am I on the right track or lost in the snow? Or would I be better to just mount the antenna horizontal aimed at the horizon and take what I can get? Jacob Tennant WF8S

Yaesu G5400-B parts needed
by w4upd 04 Mar '15

04 Mar '15

I am presently working on rebuilding my G-5400 rotator. I have the elevation unit done and seems to work fine. However, I have finally started working on the azimuth unit and find that one of the two mast clamps has a crack at the top. I was wondering if anyone has a spare(s) or a unit not working that you can part out. The rotator itself works but needs some TLC with bearings, greasing etc. The mast mounting clamp halves have the part number: 7501-075. I only need one since they are the same, but two would be fine but not necessary. You can contact me off the list. Reid, W4UPD

Re: [amsat-bb] AMSAT-BB outage and changes.

Glen Zook<gzook at yahoo.com >wrote: >Unfortunately, Yahoo is still dumping most AMSAT BB messages to the SPAM >folder. Glen, K9STH Glen, Thanks for your feedback. So far, the change I implemented seems to be working ... note that your "From" address has been "munged" such that it no longer claims to be sent from a Yahoo! server, when it in fact comes from amsat.org - the AMSAT server checked to see if yahoo.com had a restrictive DMARC policy, saw that it did, so replaced your address with the list address. Other mail servers around the internet don't see a DMARC policy violation, and list mail is delivered. Spam folders, on the other hand, are a separate problem. ISP's have a different methods of sorting spam from ham. Yahoo! has some tips for its users at: https://help.yahoo.com/kb/mail/SLN4910.html Other ISP's have their own procedures. -Joe KM1P

AMSAT P4A: the worlds first ham radio transponders in geosynchronous orbit
by Michael Fletcher 03 Mar '15

03 Mar '15

It is now the second day of the ITU Symposium and Workshop on small satellite regulation and communication systems (Prague, Czech Republic, 2-4 March 2015). The symposium is streamed live at: http://media.fel.cvut.cz/stream/itu.asx Apparently this will only work with Windows Media Player. Todays lectures just started with SSTL. There is a presentation at ~17:50 local time: "Es’hail-2 Satellite AMSAT Payload" The presentation schedule may be found here: http://www.itu.int/en/ITU-R/space/workshops/2015-prague-small-sat/Documents… This presentation covers also frequencies, polarisation data and block diagrams of the implementation. Maybe food for thought stateside, how something similar could be negotiated with the NA space industry ? With some clever planning, maybe even some continent hopping could be implemented ;-) Symposium main page: http://www.itu.int/en/ITU-R/space/workshops/2015-prague-small-sat/Pages/def… Michael, OH2AUE

Sunday my satpc32 crashed probably from picking a de orbited sat . I erased files and now my rotator is off in azimuth by 225 deg changing the turning point from N to south and calibration has no effect Pse help Thanks nick Office 337 593 8700 Cell 337 258 2527 Helping UL become a world Class Engineering and Educational School Disagree I Learn
