VY1RM is QRV Satellite from Whitehorse, YT CP20
by Doug Papay 01 Oct '11

01 Oct '11

Hello All, After many months of station design, assembly and testing, Ron VY1RM in Whitehorse, YT Canada CP20, is now QRV satellite. Ron, having been active on satellite many years ago, was already equipped with the necessary antennas and radios, but had required a rotor upgrade to get his antennas pointing automatically. This past summer, he and a team of local hams reinstalled his antennas on a G-5500 rotor at his QTH. He is now running SatPC32 to control both the rotor (with LVBTracker) and his radios. Ron's accomplishment puts a permanent satellite station in the Yukon Territory (likely the only one.) Please be listening for Ron VY1RM on both FM and linear birds in the weeks to come; give him a call if you happen to hear his callsign and welcome him back to satellite! In addition to the fact that Ron will put the rare CP20 grid within reach, the Yukon territory is also a valid entity for those who are working on the AMSAT sexagesimal or century awards. And for those up for a real challenge--the CANADAward is available from the RAC for those who complete a 2-way QSO with each of Canada's 13 provinces/territories via satellite. (not easy!) 73, Doug KD8CAO

EL18 on Sunday & Monday

I will be fishing down near Rockport, TX, Sunday & Monday and will try to make the late afternoon passes of AO-51. Sorry, but AO-27 and SO-50 are too early in the day and I don't want to take the HT either on the boat or wading :-) Equipment will be just an FT-51R and Pryme whip antenna. 73, Jerry, K5OE

New ITU Service for CubeSats and Nanosats ?
by Trevor . 01 Oct '11

01 Oct '11

The latest issue of the AMSAT-UK publication OSCAR News highlights the US NTIA proposal to create a new ITU satellite service for CubeSats and NanoSats. The proposal seeks one or more frequency bands, totalling up to 10 MHz of spectrum, to support command, control, and data relay for nanosatellites and picosatellites performing a variety of functions. It proposes that a study be undertaken after WRC 2012 so that the item be placed on the preliminary agenda for WRC 2019. It is unclear where the UHF spectrum for a new ITU service would come from. Read the NTIA proposal 'Studies for identifying up to 10 MHz of spectrum for space research service in the 400-2025 MHz range for the operation of nanosatellites and picosatellites'. <a href="http://www.ntia.doc.gov/WRC_2012/Documents/NTIA_Proposal/NTIA_Proposal_2011…" target="_blank">http://www.ntia.doc.gov/WRC_2012/Documents/NTIA_Proposal/NTIA_Proposal_2011…</a>(Nanosat).doc Other NTIA WRC documents can be downloaded from <a href="http://www.ntia.doc.gov/page/documents-and-proposals" target="_blank">http://www.ntia.doc.gov/page/documents-and-proposals</a> OSCAR News is published quarterly by AMSAT-UK and posted to members.

Width of the Earth's penumbra
by John Heath 01 Oct '11

01 Oct '11

This bb never fails to amaze me with how helpful folks can be. It was G0SFJ's postings about ARISSAt-1 MET time which set me thinking about the width of the half shadow (Penumbra) experienced by the satellite before and after eclipse. I was pointed to the simulation option in the satellite tracker Orbitron 3.17 which shows the selected satellites Eclipse condition No, Penumbra, Umbra. To activate this option click on the data tab at the bottom of the satellite listing. The simulation mode offers a variety of time steps down to 0.25 seconds. Selecting the ISS and stepping through an eclipsed part of the orbit tonight I estimated that it took the ISS 8.75 seconds to cross the Penumbra. If 7km per second is about right for the ISS then the Penumbra is 59.5 kilometres wide +/- about 1.75km. My workings may well be adrift but you get the idea. What an interesting utility, for us telemetry nuts it will add an extra dimension to solar panel data. Off to try it on some higher flying birds. 73 All G7HIA Happy Weekend

Old Oscar Sub Band 144.300-144.500
by ka9qjg 01 Oct '11

01 Oct '11

Hello hope Everyone is doing Well I "am not sure this Post went out or not If Someone has a Answer if You like Just E-Mail Me Direct at KA9QJG(a)WOWWAY.COM THANKS IN Advance 73 De Don KA9QJG Hello From Don KA9QJG , Hope Everyone is doing Well I have Heard and Read and ask a lot of Questions about Hams using the Oscar Sub Band 144.3-144.5 and as You can guess I Got a lot of Opinions From the ARRL, FCC And others, So I thought the Best thing to go was to actually get the Answers from You the users. Yes I know that and as a Responsible Ham I think We all should use the Guidelines , But in this Case From what I have found the Oscar Sats have not been on the Air since in Many Years , and NO Other Sats or ISS Is using the Freqs or set aside for them , So a Lot of Hams in the US are using the Freqs for FM/ SSB CW DIGTAL And Look the Well Established APRS 144.39 And long time and still used 144.34 FM for Conducting ATV And I have seen on the Internet Some States actually adding the 144.300-144.5 As Simplex FM The Problem is I have Heard People Jamming and Arguments about this over the Air , I have even seen on the Internet when doing searches for Info Some States even include this NON Used 144.300 TO 144.500 For FM Simplex Etc.. Because NO Oscar Sats Exist or Nothing else to Interfere with But I agree 100Percent if there Was the Freqs should NOT Be used for anything other then what it was intended for Thanks 73 De Don KA9QJG PS as You know We have a lot of older Hams kind of set in their ways and the New ones Are Listening and looking for ways to Fit in, and We need as Many New Responsible Hams in this Hobby as We can get But How Could We get on these Freqs Some are using and Say Hey We are not allowed here Because of the Oscar Sub Band Something that has been Gone for over 20 Yrs

Re: FO-29 off
by Mineo Wakita 01 Oct '11

01 Oct '11

FO-29 is now OFF status. I think that FO-29 is OFF when a ratio of the eclipse is less than approximately 11% according to my past experiment. Because the eclipse rate of these past several days is approximately 28%, the other causes are thought about this FO-29 OFF. http://www.ne.jp/asahi/hamradio/je9pel/fo29tron.htm (posted 16Nov2010) Date Mins/Day Sun% Thu 29Sep11 1034 71.81% Fri 30Sep11 1049 72.85% Sat 01Oct11 1030 71.53% Sun 02Oct11 1049 72.85% Mon 03Oct11 1020 70.83% Tue 04Oct11 1055 73.26% JE9PEL, Mineo Wakita
