Greetings. That may have been mine. I fat-fingered the cut and paste and cc’d you somehow. As always, folks were very helpful and I have been sufficiently schooled in polarization and cubesats to answer my questions. Best Todd Sent from my iPhone

Re: [amsat-bb] AO-91 and circular polarization?
by Todd Deckard 12 Mar '18

12 Mar '18

Greetings Jerry, thank you for this (yes I meant AO-92). If I understand, you are saying the the satellite uses a conventional linear antenna. However AO-92 is easy enough to access that a 3db loss from the polarity mismatch b/t linear and circular is not significant. Correct?

Oscar satellite status page
by alex weimer 12 Mar '18

12 Mar '18

has anyone else had a problem with the Amsat Satellite status page. It seems several of us when clicking on a satellite get no response as to who entered the info. However when you enter the info, it takes but all you see is whether it is red blue or yellow, Not who entered the info as normal.. What is the procedure for correcting this problem ?? JACK KC7MG

ZF2AE Grand Cayman - ZF2AE/ZF8 Little Cayman QRT - LOTW Soon
by Adrian Engele 12 Mar '18

12 Mar '18

Folks, I am now back in Chicago from my vacation as of yesterday. This was going to be a "light on satellite" operation and it appears I worked more passes than originally planned.I know I made many people happy but also disappointed a few due to equipment and location issues. I will be transcribing the recordings in the coming days and uploading to LOTW and eQSL hopefully by next weekend, so please be patient for the EK99 grid Although I prefer LOTW, if you did send me a card with an SASE I will respond with a very cool card in return. I am very casual operator and I don't get much on the satellites. Thanks for pulling me out in the pileups on FO-29 and AO-7. Sorry I did not do more FM satellites. That one AO-92 pass was enough for me to pass on doing more. Plus there are some local ZF stations that do periodically get on FM sats. Please do look into using other satellites like CAS-4B or EO-88. I got on a few passes that were completely empty. These are loud, easy to use and easy to work linear satellites. QRT for 2018. Thanks again! 73, Adrian AA5UK - ZF2AE

W3HQX Perry F. Crabill SK
by Larry 12 Mar '18

12 Mar '18

To all Metro DC area amateur radio operators: I am saddened to report to the amateur radio community that Perry F. Crabill, W3HQX, member of AMSAT, born in 1920, formerly of Washington DC and suburban Maryland and until his passing of Winchester Virginia, is now a Silent Key at age 97, as reported in Friday's Winchester Star. Perry was first licensed as W3HQX in "19ought38" as he was wont to say, worked for C&P telephone for many years, served in the US Navy in World War Two as a radio technician (passing the difficult Eddy test,) and was active for almost 70 years in a variety of amateur radio activities. Known affectionately by the 147.300 repeater's "Question Of the Day" group as "The Professor", Perry had a wide range of on-the-air acquaintances. We are diminished by his passing. There will be a memorial service and celebration of his life held on Saturday March 24th at 3:00 PM at the Jones Funeral Home at 228 S. Pleasant Valley Road, Winchester, VA 22601, 540-662-2523, http://www.jonesfuneralhomes.com/ This memorial service is open to the public and especially to all members of the amateur community. On display will be the early logbooks from W3HQX, including his first dating from August of 1938, QSL cards, and other memorabilia from his long life. Please forward this announcement to any who may be interested. Those who knew Perry are welcome to share anecdotes from Perry's life; those may be presented at the service or forwarded to Larry Wright, W8ANT for inclusion. Larry Wright W8ANT __

If you can make the direction switchable without adding too much weight, that can be helpful. We did an ARISS QSO this week and switched the polarity in the middle of it. It was just the best thing for that particular pass. ------ Original Message ------ Received: Sun, 11 Mar 2018 04:49:46 PM PDT From: Jerry Buxton <n0jy(a)amsat.org> To: amsat-bb(a)amsat.org Subject: Re: [amsat-bb] AO-91 and circular polarization? Todd, Correct is not really a consideration, the way I see it. Will a CP antenna work? Yes. Polarization should not matter for AO-92. (BTW I presume you mean AO-92, not AO-91 in which case L band just flat won't work no matter the antenna, period.) :-) I use RHCP because I built my antenna for AO-51 and that is was in use at the time. I believe that when CP is used on a satellite, at least in the AMSAT history, it has been RHCP most of the time so building for RHCP may have advantages for future satellites.
