July 27, 2008 To All RADIO AMATEURS BID: $ANS-209.01 A successful 23rd AMSAT-UK International Space Colloquium was held at the University of Surrey, Guildford, England this weekend. Prof Sir Martin Sweeting, G3YJO Chairman AMSAT-UK, opened the Colloquium on Friday. This was followed by the keynote speech given by Dr Rob Gowen, Department of Space & Climate Physics (Mullard Space Science Laboratory, University College London and Coordinator of the UK Lunar Penetrator Consortium) on "Science Penetrators for the UK MoonLITE mission". On Saturday the Delfi-C3 team gave a presentation on their exciting new satellite. Its SSB/CW 435/145 linear transponder will activated soon and is sure to prove popular with satellite enthusiasts world- wide. Saturday's Colloquium schedule also included presentations from AMSAT-DL on both the eagerly awaited P3E High Earth Orbiting satel- lite and the pioneering Mars Orbiter P5A. This will be the first private venture spacecraft to travel to the Red Planet providing Radio Amateurs with some true DX signals. A complete listing of the Colloquium Technical program can be found at: http://www.uk.amsat.org/content/view/640/213/ The IARU Satellite Forum chaired by the IARU Satellite Adviser Hans van de Groenendaal ZS6AKV also met during the Colloquium weekend. The main topic included Band planning for satellite operations on frequencies in the Amateur Service. The Colloquium included a live webcast of the proceedings via http://www.batc.tv/. There was a Live Chat page available to enable web viewers to post messages.

July 27, 2008 To All RADIO AMATEURS BID: $ANS-209.02 The Delfi team activated the Amateur Radio 435 to 145 MHz linear transponder onboard the satellite activated just before they left the Netherlands to attend the AMSAT-UK Colloquium which was held July 25-27 at the University of Surrey in Guildford, England. The Amateur Radio satellite Delfi-C3 (DO-64), built at the Delft University of Technology in the Netherlands, was launched in April. Since then it has been collecting educational research data for use by the university students with the assistance of Radio Amateurs around the world. Members of the Delfi-C3 team gave presentations during the Colloquium about their exciting new Amateur Radio satellite. The transponder can be accessed with these frequencies: Transponder mode beacon: 145.870 MHz CW Linear transponder downlink: 145.880 - 145.920 MHz Linear transponder uplink: 435.570 - 435.530 MHz All frequencies are +/- Doppler shift that can be up to 3 kHz at 145 MHz. As it's an inverting transponder a LSB signal on the uplink would be translated to a USB signal on the downlink. The transponder mode was switched on during this weekend whenever it was within range of Europe and automatically switched back to science (telemetry) mode when it entered eclipse about 1 hour later. Rob, PE1ITR reported from the Netherland on Saturday, July 26, "Today I made my first QSO around 10:53UTC and worked HA2RD with 5x7 signals. I also heard F5ETM." Alan, ZL2BX said, "The transponder was on over ZL this morning 2036UT pass with weak signals from transponder downlink and beacon. It was active again on the 2212UT pass with very good signals from both trans- ponder downlink and beacon."

July 27, 2008 To All RADIO AMATEURS BID: $ANS-209.03 AMSAT Director Contests and Awards Bruce Paige, KK5DO, provided an executive summary of participation in the 2008 AMSAT Field Day. The results will be published in the July/August AMSAT Journal. This includes some really nice photos that were sent in. Detailed results will also be posted in an ANS bulletin. This year, we had 8 satellites used. There was even one QSO on AO-16. A total of 120 QSO's were reported and we had 17 stations submit scores. The most contacts were done on VO-52 this year. Behind that was AO-7. Here are some statistics from this year and previous years: 2005 2006 2007 2008 Satellites 8 7 5 8 QSO's 120 258 207 220 Stations 11 21 13 17 Watch your mailbox for your copy of the AMSAT Journal and standby for more Field Day news via ANS.

July 27, 2008 To All RADIO AMATEURS BID: $ANS-209.04 Jason Anderson, KI6GIV, at California Polytechnic State University is requesting amateur radio operators worldwide to assist with capturing the telemetry of the Cal Poly CP4 satellite. Jason wrote, "We have seen some unpredictable behavior on our satellite, CP4. Since we only have contact with the satellite once every 12 hours, it would be extremely helpful if we could get some global support with collecting beacons to get a more complete picture of the the satellite's health."

July 27, 2008 To All RADIO AMATEURS BID: $ANS-209.06 + The European Space Agency has announced the commencement of payload selection for VERTA-1, the Vega second flight. The primary objective of the VERTA-1 mission is to demonstrate the multiple-payload capa- bility of the Vega launch system into a low-Earth, Sun-synchronous orbit in the 500-800 km altitude range. Payload opportunities are open to any private or public entity, without restriction as to nationality. For more information see: http://www.esa.int/SPECIALS/Launchers_Home/SEM3MKXIPIF_0.html + FO-29 has been only turned on over Japan for several months as the ground controllers worked on battery power managment to conserve this satellite for as long as possible. This past week several reports have been received that FO-29 has been heard over most of its orbit in other parts of the world. Frank, VK5MFW reported contacts with ZL2BX and ZL1BVA. Mak, SV1BSX reported a contact with SW1JGW and DL6HP. Users are encouraged to continue to be careful with this satellite's power budget and cease operation if the downlink signal weakens or experiences FM shifting.

Presentations on P3E and the Mars Orbiter P5A
by Trevor 26 Jul '08

26 Jul '08

The Amateur Radio Mars Orbiter P5A and the High Earth Orbit (HEO) P3E will feature in presentations given by AMSAT-DL on Saturday July 26th, at the AMSAT-UK 'Satellite Weekend' which is open to all. The Amsat P5-A will be the first spacecraft built by Radio Amateurs to go to the Red planet and the first ever private interplanetary spacecraft. It will use frequencies in the Amateur Satellite Service allocations at 2.4 and 10 GHz. A video of P5-A 'With AMSAT P5-A to MARS' can be seen at http://www.youtube.com/watch?v=iIJ548EyUME Pioneering spacecraft like these demonstrate the need for the both the Amateur Radio and Amateur Satellite Services to have access to Low Noise Floor allocations in the microwave spectrum so they can carry out weak signal experimentation. The P3E presentation by Peter Guelzow DB2OS takes place at 11:30 am (1030 GMT) on Saturday. He will followed by Achim Vollhardt DH2VA with the presentation on the Mars Orbiter P5A. Thanks to the BATC both presentations will be streamed live to the web at http://www.batc.tv/ New for 2008, it has been arranged with the University for "walkin" day visitors for £10 per day.

Re crossed yagi question.
by Angus 26 Jul '08

26 Jul '08

OK now that I have a crossed yagi in the X format, I must say I am very pleased with its performance. Here is the question with the yagi in the X format, does it perform as well when set with delay lines to horizontal polarity as a yagi with the same gain beam width etc set in the horizontal polarity? I ask this as I don't have a lot of test equipment and most of my results are a 'by ear' equipment. I just wonder if anyone (someone will have I am sure) has done any checking to see what if any difference there is between X set to Horizontal and a normal yagi set in horizontal?

go-32 techsat1b
by Mr Jeffrey L Ross 26 Jul '08

26 Jul '08

Hi folks, going to try again this am pass. I feel there is nothing coming from go-32 again but will give it another shot. I Have a good pass at 73 degrees over head. I Thought I would let everyone know that you can get a whole page of data without moving the antenna or the doppler. This information is good to know. I have done it before. At least from this sat. The address to write techsat1b was no good but will keep trying. (website) Looks like the last time they reached up to her was 2002. Hopefully not. Anyway wish me luck. USA pass is 1049 am. kc8gkf

FO-29
by Frank Woolfe 25 Jul '08

25 Jul '08

Great contacts with ZL2BX and ZL1BVA on FO29's 0200UTC pass from the centre of VK "PF88jt". It seems another "Blast from the past" has come back to life (well done fella's) Unfortunately when it got further north the same problem as always north of VK, the 2m Rx bombarded with every Pirate in Indonesia, Philippines, and Malaysia etc...Who would build an uplink on 2m these days stick to the tried and proven 70cm up 2m down, the only way to go...

FO-29 is back again !
by SV1BSX 25 Jul '08

25 Jul '08

Hello all, after Robert-G8ATE's report on Amsat-BB, this evening I tried together with my friend Dimitris, SW1JGW, a test on FO-29. Well, yes indeed, the Satellite is active again ! Just after the AOS we heard clear the Beacon, and then I had a nice QSO with SW1JGW (21:36Z) ! After that I changed my frequency a bit lower and I had a 2nd QSO with DL6HP (21:38 Z). Both, Dimitris and I, we were QRP ! 5 Watts for Uplink were enough for excellent return signals on Downlink. By using QRP we tried to avoid any overloading of the bird. The Satellite was really Booming, always 55 - 59 with "crystal audio". However, at 21:38 my return-signal rapidly decreased, but even much lower it was easily readable. After that I interrupted my TX and I return onto Beacon frequency. Q5 now, but still "clear" ! Later I noticed that on my tracking software, precisely at this time the Satellite came on a new Eclipse ! So, probably the old-Batteries are not strong enough in order to support the same Downlink-power in eclipse, like that on Sunlight. Also I observed some FMing at this point and I lost the signal before the LOS, but on this direction I have not "clear horizon" (but High buildings), so I can't say with accuracy if the Satellite was still "ON" or not. Sorry ! Anyway, the FO-29 is back again ! Great news ! CU on FO-29 ! 73 de Mak, SV1BSX Email: sv1bsx "AT" yahoo .gr URL : http://sv1bsx.50webs.com

Vertical MOXON antennas for satellites
by WB2LLP 25 Jul '08

25 Jul '08

My somewhat porous memory says that L. B. Cebik wrote a couple of articles on using vertical Moxon antennas to create omni-directional 144 and 432 antennas for satellite frequencies. I can not find those articles in my shack. Is there someone with a better organized magazine collection who can tell me what magazine and issue.? TNX es 73 de WB2LLP Gene
