Brief AO-51 schedule change 5 August 2010
by Mark L. Hammond 04 Aug '10

04 Aug '10

There will be a brief change in AO-51's schedule as follows: We are currently running only the 435.300 voice transmitter at about 750 mW with PL tone activation of the transmitter. On 5 August from approximately 9:55 utc to 21:05 utc AO-51 will be running the 435.150 telemetry transmitter ON at 340 mW and the 435.300 voice transmitter at about 470 mW with PL tone activation of the transmitter. We are making this mode change in order to provide a telemetry collection demonstration for a cubesat team. Around 21:05 utc (or the next pass, which is 22:44utc) the change back should occur ( the 435.300 voice transmitter at about 750 mW with PL tone activation of the transmitter, 435.150 transmitter OFF). 73, -- Mark L. Hammond [N8MH]

Lake Superior Trip 1st Day
by John Papay 03 Aug '10

03 Aug '10

We got a late start today, leaving around 1530z. Only one pass was attempted, AO-51 at 2226z. The location was EN84FG Tawas, MI, in a park on Lake Huron. Seventeen contacts were made including one with TI2SW who made a rare appearance. Also worked XE1AO early in the pass. We are in Alpena MI now which is in EN85. Tomorrow we continue north to Sault St Marie on the US side. The next day we will be in Canada in EN85 and EN86. So far the equipment is working fine. It is hot here, 91 this afternoon. Thanks to all who worked me from Tawas. Recording made from EN91 is on my website. 73, John K8YSE/p John Papay john(a)papays.com

AO51 was off last pass. Thanks to PY5LF for the spot on the Carr page. I think it's a simple fix and we should have it back on this coming pass. 73, Drew KO4MA Sent from my iPhone

Midwest Dual Amateur Radio Balloon Launch August 7
by JoAnne Maenpaa 03 Aug '10

03 Aug '10

Relaying this information since there are likely several interested Amateur Radio operators within range ... The Upcoming ARISS Contact Schedule reported today that the ISS contact scheduled for Saturday, August 7 with the Boy Scout Space Jamboree in Rantoul, IL has been aborted due to the cooling problems on the ISS. Rantoul, IL is approximately 100 miles south of Chicago and 15 miles north of the University of Illinois in Champaign. Space Jam has posted a message inviting amateur radio operators in IL, IN, WI, OH, MO, KY and beyond to monitor VHF and UHF for a dual balloon launch with Amateur Radio aboard on August 7: Balloon 1 --------- DePauw University Balloon Assisted Stratospheric Experiments (BASE) project Flight 48 Scheduled to launch approx.

Re: K8E in EN57 and EN67 (was no subject)
by Michael Rudzki 02 Aug '10

02 Aug '10

Damon, If you were on AO-51 this afternoon/early evening, the callsign was K8E. We are in EN57 (Eagle Harbor, Michigan) for the week and are planning to travel up to EN67 one day this week. It's supposed to rain on Monday, so that may be out. I am using two HTs and an Arrow Antenna. I don't use FM sats that often, so I take it SO-50 and AO-51 are my best choices, since HO-68 is in SSB/CW mode this week. QSL via N8MR, if you want to confirm. 73, Mike, N8MR (no subject) -------------------------------------------------------------------------------- Subject: [amsat-bb] (no subject) From: wa4hfn@xxxxxxxxxxx Date: Sun, 1 Aug 2010 22:39:14 +0000 (UTC) -------------------------------------------------------------------------------- OK what call is correctÂ K8E or K8EEN AO51 pass@22:16appx WA4HFN

(OT) DKIM Signature
by Ron Miles 02 Aug '10

02 Aug '10

Is it just me or does anyone else receive this tremendously long DomainKey Identified Mail (DKIM) Signature such as above for Subject line: K8E in EN57 and EN67. I guess its purpose is to limit spam, spoofing, phishing etc, but isn't DKIM overkill for AMSAT-BB purposes. Just thinking out loud 8-) Ron n6paa

August 1, 2010 To All RADIO AMATEURS BID: $ANS-213.02 UK Space Agency to launch CubeSat The UK Space Agency has announced a one-year pilot programme to design and launch a CubeSat and is running a competition for ideas for payloads. This miniature, cube-shaped satellite will allow the UK to test new space technologies and carry out new space research 'cheaply' and quickly. The pilot programme, named UKube 1, will use a spacecraft platform that is currently under development by the company Clyde Space Ltd and will involve a competition amongst companies and academic groups to come up with the most innovative ideas for payloads. The winning payloads will be launched on the satellite in mid 2011. Companies and academics who are interested in designing a payload can contact the UK Space Agency for more information. There is another CubeSat under construction in the UK called FUNcube. It is being built by AMSAT-UK and the hardware will be shown at the AMSAT-UK International Space Colloquium in Guildford July 31 - Aug 1.

August 1, 2010 To All RADIO AMATEURS BID: $ANS-213.04 In association with Tom Webb, WA9AFM/5, President, Oklahoma City Autopatch Association, the North Texas Balloon Project would like to dedicate their Launch No. 18 to the memory of fellow ham, John Mark "Rob" Robbins. Just two weeks ago, John Robbins, NO5X, became a Silent Key. John was a founding member of the Near Space Exploration Group in the OKC/Tulsa area. We conducted several balloon launches from OKC until John's health prevented his participation and leadership. It was John's goal to do a record setting flight for an amateur radio balloon. He came very close, but never succeeded. The John Mark Robbins Memorial Flight will be launched by the North Texas Balloon Project (NTEXBP) at about 8:30 am CDT on August 7, 2010 from the municipal airport in Hillsboro, Texas, just south of Fort Worth and Dallas. The public is invited to come out to the Hillsboro Municipal Airport, located at Exit 3 on Interstate Highway 35W, to watch the launch. The back up launch date is August 14, 2010. Three payload packages containing sensors and amateur radios will be carried to nearly 100,000 feet in about 90 minutes by a helium balloon and return via parachute in about 50 minutes. Mobile recovery teams will use position reports from the onboard GPS and APRS transmitter on 144.390 MHz and radio direction finding techniques to recover the payloads. A cross band repeater will be activated soon after launch. Uplink is 4 45.800 MHz and downlink is 147.560 MHz. At the peak altitude ham radio operators from Texas, New Mexico, Oklahoma, Arkansas, Louisiana, and Kansas can contact each other using the cross band repeater. The third payload of the flight is a ten meter beacon operating on a frequency of 28.274 MHz. The antenna is a home brew loop and the transmitter will be running approximately 1 watt. This beacon may be heard world wide if the band is open. Please report reception and we will happily QSL the event. Email webmaster(a)ntexbp.org or kdvickers(a)aol.com Pre-launch activities will begin about 7:00 am CDT with the HF Launch Net on 7260 +/- 5 KHz, LSB beginning around 8:00 am CDT. Follow us on HF radio or on Twitter@NTEXBP . Saturday's launch will show on APRS as W5SJZ-11.

UO-22 just 100000 on 3rd Aug 2010
by Mineo Wakita 02 Aug '10

02 Aug '10

UO-22 was launched on 17 July 1991. It's now Non-Operational. I predict here that UO-22 might be passed over just 100000 of the orbit number using the latest TLE. OSCAR 22 (UoSAT 5) 1 21575U 91050B 10212.53322685 .00000036 00000-0 25462-4 0 8963 2 21575 098.4959 161.9541 0006690 228.5705 131.4898 14.39726937999601 100000 - 99960 = 40 ... orbit numbers until 100000 40/14.39726937 = 2.778304619 ... orbits/mean motion = days 212.53322685 + 2.778304619 = 215.311531469 ... epock time 215 - 212 = 3 ... 3rd Aug 2010 0.311531469 * 24 = 7.476755256 ... 7 hours 0.476755256 * 60 = 28.60531536 ... 28 minutes 0.605315360 * 60 = 36.31892160 ... 36 seconds Therefore it is 07:28:36 UTC, 3rd Aug 2010. It maybe contains +/- one and a half hour's obserbational lag. In addition, the counter number returns to 0 when the orbit number exceeds 100000. JE9PEL, Mineo Wakita
