Invitation to Big-Dish EME Project
by Mikio_Mouri 16 Feb '07

16 Feb '07

Dear Satellite friends, You may be interested in having EME QSO with your antenna and rigs! A Japanese EME group is, with many organizations (including us), setting up 32m-Dish EME station in Ibaragi, Japan. Target is to QRV 144MHz, 432MHz, 1296MHz and 5.6GHz from 23 Feb to 24 March at possible windows. Please check his home page and you will find its progress: http://8n1eme.jp/modules/news/ Thank you for your interest and support. Best regards, JA3GEP, Mikio Mouri, JAMSAT

How to de-ice your antennas and rotors by K1XT
by Kyle Yoksh 16 Feb '07

16 Feb '07

Hi everyone, I found this the other day while surfing the web. Hope you get a good laugh like I did: Many years ago on a cold winter morning I was at the house of good ham friend of mine during a contest. A small ice storm had passed through during the night and the antennas had refused to turn. "Jim. The Yagi is frozen," I said. "We'll get it turning," he said calmly. "Come on." I followed him to the door and before stepping out, he grabbed a 410 shotgun that had been standing by the door. We walked out into the back yard, and I watched him as he proceeded to fire several rounds of bird shot at the yagi and rotor. It was humorous to say the least as I watched the ice explode from the elements at each shot. In short, that took care of it. And when up working on the antennas that spring, I never noticed any damage to them. "Over the years I have perfected the load," he told me one day. "I load about dozen shells in the fall in anticipation." Funny to see, but it sure worked. Bill K1XT 73, Kyle Yoksh K0KN Olathe, Kansas Amsat# 35249

big wheel on sats
by pcalvi＠bluewin.ch 15 Feb '07

15 Feb '07

Hello everybody. Has anybody had a practical, hands on experience with big wheel antennas with LEOs? I know the radiation pattern does not favor higher elevations, but I don't know ho actually low the radiation angle is, and looking for somebody with experience. Thanks, Piero HB9DSU

Info needed.
by Stargate 15 Feb '07

15 Feb '07

Hi all, Well, It's time to start considering antennas for my satellite station. (tax refund:-) I am trying to pack as many modes into my station as I can. I have the following so far.... Yaesu FT-847 AOR 8600 MK2 receiver (dc-3ghz) Icom IC-706MK2G Mirage 2530 (300 watt 2 meter amplifier) Astron RS-70M power supply G-5500 rotor LVB tracking board SAT688 tracking board Orbitron tracking software Andrew CF2P coax (2.7db loss 100' @ 450mhz) I will be running the coax in about 50-70' runs from the shack to the antennas. I would like to have mode S receive as well but the loss gets rather high with this coax so hardline or a mast mounted downconverter may be the way I go. I'm pretty sure I want circular polarized antennas unless someone talks me out of it. Switchable for LHCP or RHCP?? Whatever VHF and UHF antennas I choose will also be used for terrestrial work as well. Unfortunately, my terrestrial work is somewhat limited due to the topography of where my house is. I will also be adding mast mounted preamps sometime in the future. I'm confusing myself with all the modes and options so what do you recommend? All comments appreciated very much. RoD KD0XX A good friend will come and bail you out of jail, A TRUE friend will be sitting next to you saying..... "DAMN THAT WAS FUN"

OSCAR-11 Report
by Clive Wallis 15 Feb '07

15 Feb '07

OSCAR-11 REPORT 15 February 2007 TELEMETRY & NEWS ARCHIVES I have now uploaded an archive of the telemetry for 2006 to my website. The zip package contains 86 individual telemetry files. The names of the files are date coded, and there are accurate date/time stamps within the data. I have also uploaded an archive of all these reports for 2006, as a single file. www.users.zetnet.co.uk/clivew/ TELEMETRY AND REPORTS WANTED! To investigate the on-board clock's hour problem, mentioned below, I would welcome some telemetry from differents parts of the world, at times when the orbits do not pass over the UK. These times are approximately from 10:00 to 16:00 and from 19:00 to 04:00 UTC. If you don't have a decoder, I can now accept short WAV files of good audio, duration up to 30 seconds. I would also like reports of reception around the times of expected beacon switch ON and OFF. No telemetry wanted, just when you listen, and whether you heard, or didn't hear the bird. Please e-mail to the address below. -------------------- During the period 23 January to 14 February 2007, the satellite was heard from 28 January to 08 February. Good steady signals have beeen heard on most passes, and good copy of the telemetry obtained. The on-board clock has maintained accurate time. Over the reporting period, no change could be detected! However the hour counter sometimes shows an error of of 10 hours, ie. in its most significent digit. The 'day of the week' counter operates reliably, zero representing Thursday. The date counter appears to be incrementing correctly, but the day of the month is not reset to one, at the end of each month. On 07 February it reset to 41, showing that the unused bit representing 40 permanently is stuck at a one. This means that the clock error is now 37.21453 days slow. If the satellite's watchdog timer continues to operate normally, the beacon should switch ON around 18/19 February 2007. The satellite is in full sunlight at the present time, and will remain in this state until mid-April 2007, when eclipses start again. I am indebted to David G8OQW, Mark KU7Z, Jay KD4QoV, Etienne ZS6Y, Jeff KB2M and Geoff ZL6GA for their reports. Many thanks. The current status of the satellite, is that all the analogue telemetry channels, 0 to 59 are zero, ie they have failed. The status channels 60 to 67 are still working. The spacecraft computer and active attitude control system have switched OFF, ie. the satellite' attitude is controlled only by the passive gravity boom gradient, and the satellite is free to spin at any speed. When telemetry was last received it showed that one of the solar arrays had failed, and there was a large unexplained current drain on the main 14 volt bus. After 22 years in orbit the battery has undergone around 100,000 partial charge/discharge cycles, and observations suggest that it cannot power the satellite during eclipses, or sometimes during periods of poor solar attitude. The watchdog timer now operates on a 20 day cycle. The ON/OFF times have tended to be very consistent. The average of many observations show this to be 20.7 days, ie. 10.3 days ON followed by 10.4 days OFF. However, poor solar attitude may result may result in a low 14 volt line supply, which may cause the beacon to switch OFF prematurely, and reset the watchdog timer cycle. When this occurs, the beacon is OFF for 20.7 days. The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF Listeners to OSCAR-11 may be interested in visiting my website. If you need to know what OSCAR-11 should sound like, there is a short audio clip for you to hear. The website contains an archive of news & telemetry data. It also contains details about using a soundcard or hardware demodulators for data capture. There is software for capturing data, and decoding ASCII telemetry. The URL is www.users.zetnet.co.uk/clivew/ If you place this bulletin on a terrestrial packet network, please use the bulletin identifier $BID:U2RPT130.CWV, to prevent duplication. 73 Clive G3CWV xxxxx(a)amsat.org (please replace xxxxx by g3cwv)

DE-xpedition Announcement
by melachri＠speakeasy.net 15 Feb '07

15 Feb '07

I am planning a short trip to Delaware (a DE-xpedition, so to speak) to operate the FM satellites, and give others a chance to work this state. The trip is tentatively planned for 24 February 2007, during the local afternoon and early evening. My location is going to be close to 39.82N-75.55W, in the northwest corner of FM29. This is where I was for a previous DE-xpedition on PSK31. Equipment will be a Yaesu VX5R with a handheld Arrow dual-yagi and an MP3 recorder. Thanks to Patrick WD9EWK, I have some predictions of satellite passes from this location, and have selected the following: AO-27 2003z-2019z AO-27 2145z-2157z (dinner break) SO-50 2318z-2329z AO-51 2333z-2346z SO-50 0057z-0110z (UTC 25 Feb) AO-51 0111z-0125z (UTC 25 Feb) This schedule is subject to change, based on weather or other logistical issues. I hope this trip will be of interest to the satellite community. I do have two requests: 1. Since I will be operating half-duplex (due to radio limitations), I would appreciate it if anyone who is able to record these passes would email the recordings to me afterwards. 2. I'd also like to gauge interest in this trip, so if you are specifically interested in working me (for either the state or the grid), please let me know via direct email. Thanks. 73, Steve Melachrinos W3HF (@arrl.net)

antenna construction
by randy 15 Feb '07

I have been wanting to put up long boom oscar antennas for 2 meter and 435 bands but the prices are very high. Are there any websites out there with plans that show how to build a cross polorized antenna for these two bands. I'm sure one could be built for half the price of the M2 satellite antennas. Also i have search the internet for plans that show how to build the circular polorization switch for LHCP/RHCP but have yet to find one. Any help will be greatly appreciated.

Luc, Your research is faulty. This information below is not the same Falconsat as the USAFA satellite I mentioned: >>From a NASA agency NSSDC Master Catalog Display: Spacecraft > >FALCONSAT > >NSSDC ID: 2000-004D >Other Names > > * 26064 > >Launch Date: 2000-01-27 >Description > >FALCONSAT is an American military microsatellite that was released from JAWSAT. > >It is reported to be a technology testing mission. >Discipline of surveillance and other Military uses. (edited) > >Sponsoring Agency/Country > > Unknown/United States > Furthermore Falconsat-3 is not a AMSAT-NA project. There has been no AMSAT-NA funding for Falconsat-3. There has been no allocation of personnel or money by the BOD or the Officers for Falconsat-3. The USAFA is a university, building a scientific and amateur satellite, no different in kind from Sunsat, PCsat, most of the cubesats, many of the RS series, or any of the University of Surrey satellites. The builders and control ops of these satellites can do as they please with their own time and money, and badgering by the likes of you may deprive hams from the use of a fine satellite. Do yourself a favor and quit looking for a conspiracy under every rock and stone, and do your homework before you point a finger at the people who volunteer their time and money in an altruistic fashion. > >Did AMSAT-NA will condemned military endeavour or support it?
