I think that the hardware, whether sitting on a shelf or being built, is rather expensive go around blowing up. Not to mention the work put into designing and building the things.

Re: AO-27 pass 10 Jan 1840z

...and to Bob, the pass was well-handled on your end, btw (on _both_ ends of the Q's, actually). A credit to everyone; I was expecting total chaos. Patiently waiting as the "big" stations get their grid/entity, hopefully we "handhelds" will get the Q. I made a lot of Q's after you left my foot-print on that pass. :-) Does your schedule allow you to work the earlier passes as well (e.g. the 16:55 - 1710 pass today, along the east coast) Bill W1PA (FT-530 and Arrow)

A 2U CubeSat aiming for a launch in 2014, see http://www.uk.amsat.org/3637 The specification document says "145 MHz and 347 MHz tranceivers. VHF is primary downlink, UHF is primary uplink" I presume the 347 MHz is a typo and should be 437 MHz. 73 Trevor M5AKA AMSAT-UK: http://www.uk.amsat.org/ ----

Palm Springs HamFest 01/28/12
by Clint Bradford 10 Jan '12

10 Jan '12

AMSAT area coordination Clint Bradford K6LCS will again be attending and demonstrating working ham satellites with minimal equipment at the third annual Desert Radio Amateur Transmitting Society's HamFest on Saturday, January 28, 2012. "Although we have recently lost two FM ham satellites - AO-51 and ARISSat-1 - we still have "easy birds" of AO-27, SO-50, and the ISS to work with minimal equipment," Clint reports. "We have tentative passes of AO-27 and SO-50 in the afternoon to work during the Hamfest." If you are interested in working one of these passes with Clint, download his four-page tutorial with frequency tables at ... http://www.work-sat.com Clint will have info at his table on working the satellites with just your handheld radio, as well as info about the upcoming ARISS project in April: students at Riverside's Flabob Airport are gearing up to speak with an astronaut aboard the ISS.

I: [CubeSat] Nanosat frequency spectrum issues & the World Radio Conference 2012
by Gi. (Ab2vy) 10 Jan '12

Sent from my BlackBerry® wireless device -----Original Message----- From: Wouter Jan Ubbels <w.j.ubbels(a)isispace.nl> Sender: cubesat-bounces(a)cubesat.org Date: Mon, 9 Jan 2012 15:53:32 To: <cubesat(a)cubesat.org> Subject: [CubeSat] Nanosat frequency spectrum issues & the World Radio Conference 2012 Dear smallsat / nanosatellite / CubeSat developers, as you may be aware, obtaining frequency spectrum for nanosatellites is not always easy. Especially, experimental / technology proof-of-concept demonstration missions find it increasingly more difficult to find spectrum in todays crowded bands. Whilst for some missions, amateur radio spectrum might fit the bill, for others this is less suitable since the mission does not fully meet the criteria in order to operate in the bands allocated to the amateur satellite service. On the other hand, "commercial" or research space allocations often are not feasible from a budget point of view because of the large fees involved, and the associated long coordination times may far exceed the time to design, develop and build a small / nanosatellite. Through experience from our customers, and also through our own, ISIS has identified this problem as a potential long term showstopper for the emerging nanosatellite market. We will attend the World Radio Conference later this month as part of the Dutch national delegation. Although nanosatellite spectrum is not on the agenda of this WRC, we plan to make use of the opportunity to informally sound the various opinions on this matter and investigate potential possibilities for creating a future proof solution ensuring the spectral needs of the community are met. This is potentially in line with discussions already going on in for example ITU study group WP7B. If you have any input on this matter, we would love to hear from you so we can take this into account during our informal discussions with the various attendants at the WRC. Also, if you are present at the WRC yourself, this might be an excellent opportunity to discuss the topic in person. We might be able to share some preliminary observations during our presentation at the European CubeSat Workshop in Brussels later this month. kind regards, Wouter Jan Ubbels -- Wouter Jan Ubbels, MSc ISIS - Innovative Solutions In Space B.V.

Humor

Two antennas met on a roof, fell in love and got married. The ceremony wasn't much, but the reception was excellent. Since they were a perfect match, soon they generated harmonics. They wrapped the harmonics in dipoles. But later the harmonics turned out to be parasitic elements. The true story -- she was a tri-bander and he felt trapped, so they went on separate beam headings Kevin KF7MYK

I will QSL direct to all contacts that are in my log. I will also upload to LoTW (as soon as I figure out how to make a new account) and to Eqsl. No SASE needed. This will take place once I return home in mid February. Hope to work you on AO-27 and maybe SO-50. 73, Bob - HI4/AJ5C

Re: CHIBIS-M satellite to launch to ISS
by Andrew Glasbrenner 09 Jan '12

> >The payload is a scientific satellite to be deployed from the ISS/MKC to study the magnetic field in the auroral zone. Interesting: "This experiment provides a comprehensive study of physical processes in atmospheric lightning discharges. Delivery of the microsatellite in its working orbit at an altitude of 500 km will be done with a THC "Progress M-13M" after the completion of the flight of the truck in the station. According to the developers of the term of active existence of the spacecraft, "Chibis-M" will be at least one year." It looks like they plan on raising the Progress after undocking, then deploying the satellite. This sounds like a new capability for Progress, and similar to what I've seen discussed for Dragon by SPaceX. 73, Drew KO4MA
