Re: LHCP or RHCP?
by Tom 07 Oct '10

07 Oct '10

Perhaps I should have worded my question differently. I understand the concept of circular polarization and the reasons for it. What I should have asked was "Is one direction preferred over the other for working the satellites?". Thanks for all the excellent info and I think what I've learned is that the ability to switch between directions of polarization is best but RHCP is preferred if only one direction is available. Domenico, thanks for the attachments. Good stuff which I had not seen before!

LHCP or RHCP?
by Tom 06 Oct '10

06 Oct '10

On the premise that the only dumb question is the one that goes unasked, here goes. If I'm building an antenna of circular polarization for use with the birds what determines if it should be LHCP or RHCP? I've read the ARRL Satellite Handbook and "sort of" searched the AMSAT-BB archives but found nothing about this question. Thanks. Tom - K0TW

Help required for KiwiSAT.
by Terry Carrell 06 Oct '10

06 Oct '10

>From the KiwiSAT team. Can you help us? We require four (4) Cypress CY7C383A-0JC or QuickLogic QL12x16-2PL68C FPGA chips, used & un-programmed. To date we have had 2 lots of 4 from two different sources but all proved to have been compromised and could not be programmed. We had a small stock but they have all been used during our development work and while we can purchase new units, the source requires us to buy a significant number more than our requirement which is proving to be very expensive. We are happy to pay for good units once we have confirmed they are clean. A matter of twice bitten, thrice shy. These chips will fly so it is important we have perfect units. If you help in any way, please let me know. Terry, ZL3QL. – AMSAT-ZL

S band
by Jack Barbera 06 Oct '10

06 Oct '10

Need a little help. First I'd like to thank everyone for your answers to my question concerning ISS beacon. I am all set to add L band to my station using my IC910 including Rohn 25 folder over tower to be mounted to the side of my house. While I'm at it I wonder if it would make sense to add S band as well, if so, should I add transmitting as well as receiving capabilitie? Should I use a two meter or a 70 cm radio knowing that two meter would provide less loss? Any thoughts on this would be appreciated & most likley I will have further questions as I get into this project. Thanks for any input. Jack WA1ZDV

Re: SatPC32 Help Needed
by Edward R. Cole 06 Oct '10

06 Oct '10

David, I'll step in here with a brief comment which you may already have considered: Doppler frequency offset changes throughout a pass, so if you transmit on a fixed frequency on the uplink, the downlink frequency will change due both due to Doppler effects on the uplink and downlink frequencies. If this is mode-UV the amount of Doppler will be more on the uplink due to the higher frequency. Another effect that many do not take into mind is that Doppler changes at a non-linear rate; in other words it changes faster near the point where Doppler goes from positive shift to negative shift in the rest frequency of the satellite. I know it sounds like a lot of math. But as an operator you just need only realize that this will happen resulting in tuning the signal over the duration of the pass (tune faster at mid-point of pass). When one gets up to modes like LS, it gets more challenging because both Doppler and rate of Doppler change are greater. Probably should consider computer tuning of the radio at this point. Note that Leo satellites go thru faster frequency change due to the quicker pass overhead. Heo's taking hours for a pass require retuning less often. Others may provide more definitive help with your question. 73, Ed - KL7UW At 11:35 AM 10/6/2010, David Palmer wrote: >Hi Guy and Amsat-List! > >I'd like to know the answer to this too!

SatPC32 Help Needed
by Guy Brauning 06 Oct '10

06 Oct '10

Thanks for reading this. I recently installed SatPC32 from an AMSAT purchased CD onto a new WIN 7 laptop with a dual-core Pentium processor. The laptop is interfaced with a Yaesu FT-857D for 144MHZ and a Yaesu FT-897D for 432 MHZ. The interface is via a STAR-TECH Express Card serial adapter which provides 2 COM ports. The program installed properly, I updated the KEPs file, and the program controls the radios. My problem is that I can't fine tune the Doppler shift properly for my set-up. I have tried using the CAT Tuning dialog box to adjust the Downlink in order to hear my own CW signal in the downlink, then reset the downlink adjustment to zero, and then adjust the Uplink by the same frequency amount in the opposite direction, and then save the uplink calibration. I was able to get AO-7 mode B working pretty well using this technique; however, for VO-52 even when I adjust the downlink to hear myself and then change the uplink and store the change, my signal is no longer heard in the downlink... even before saving any changes, I have to continually adjust the downlink in order to hear my own signal as my signal will move out of the downlink ....I can't seem to find the correct Doppler corrected frequency pair... I thought that once I adjusted the downlink so that my signal was peaked that that would be a constant "correction" throughout the pass. Are there other adjustments that I need to try in addition to the uplink calibration? FO-29 is even harder to try and figure out than AO-7 and VO-52. Is anyone else using two Yaesu FT-817 / 857 / 897 rigs with SatPC32? If so, what do you think I am doing wrong and what are your DOPPLER.SQF data lines for AO-7, VO-52, and FO-29 (as well as any other critical settings)? I have been manually adjusting for Doppler shift for about a year on the linear satellites but I never got proficient enough to tune around the passband and answer other calls... I just parked myself on an open frequency and called until someone answered me. I can greatly appreciate the benefits of Full Doppler Tuning, I just can't seem to configure SatPC32 in order to take advantage of it! I live in central Maryland, FM-19. Thanks for the help, Guy Brauning N3SCR guyjeanbraun(a)comcast.net

Possible ops from rare grids ..
by John D'Ausilio 06 Oct '10

06 Oct '10

I'm making a trip to the canadian maritimes .. I've borrowed an Arrow antenna, have a number of radios (still trying to find my VX-5 which is missing) .. should be able to do FM and maybe SSB/CW as well .. I'm staying in GN06, will certainly be in FN96/95 .. might be able to do GN05 then on the way home were going to Halifax, if there's a grid there that's near and dear to anyone's heart let me know direct. I'll try and identify specific passes once the route is settled, and I'll post updates here (unless there's a better place to do so?) de w1rt/john

Not sure which to pick, but having both is valuable. For example HO68 is tumbling a lot (looking at my switching between L and RHCP). AO51 has more stable results: 435.300 vs 435.150 ((I always forget which one is what). 73, Henk -- Henk, PA3GUO

OSCAR-11 Report
by Clive Wallis 05 Oct '10

05 Oct '10

OSCAR-11 REPORT 30 September 2010 This report covers the period from 30 March to 30 September 2010. During this time the satellite was silent until it was heard by JA0CAW on 29 August. Since then, it was heard until 08 September and from 18 to 29 September. Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames. There has been a significant change since the previous period of activity which ended in March 2010. The on-board clock is now very stable. It's gained only three seconds in 30 days. This is comparable with its accuracy when the satellite was fully operational. During its first 21 years it gained approximately one minute per year. However, there is still an accumulated loss of 309 days, which has occurred during eclipses of the last few years.! The other change is that it's now transmitting during eclipses, although signals are weaker at those times. This indicates that there is still some capacity remaining in the battery. These two changes suggest that some part of the system may have recently failed 'open circuit' thus reducing the overall power drain of the system, and allowing more power to be available during eclipses. There was an unexplained current drain observed when analogue telemetry was last transmitted. This fault might have cleared. Interestingly, the status telemetry shows that the Digital Store & Readout experiment has switched off, since the satellite was previously heard in February. The satellite appears to be operating for ten days on, followed by ten days off, so it should start transmitting again around 09 October. The Beacon frequencies are - VHF 145.826 MHz. AFSK FM ASCII Telemetry UHF 435.025 MHz. OFF S-band 2401.5 MHz. OFF Reception reports have been received from Bernard FY1LE, Roland DG1EBR, Mike DK3WN, Tetsu JA0CAW, Adam SQ8MFC, MM0DNX, Tony VK3KKP/G8HIM, Martin DC1MAR, John M0BIC, Etienne F1GRR and Carlos KD6GRF. Many thanks to everyone. Many reports have also been added to the live satellite status page, on the website set up by David KD5QGR and Bob WB4APR. This is a very convenient and easy to use facility, which shows the current status of all the amateur satellites. Strongly recommended for future reports! The URL is http://oscar.dcarr.org/index.php For the benefit of new listeners, here is a short history of OSCAR-11. It was lauched in 1984, providing telemetry and other digital services for amateur radio and educational users. During its many years of operation it survived long periods of eclipses and continuous full sunlight. In 2002 the satellite reverted to its default mode of operation, controlled by the watchdog timer. In 2005 all the analogue telemetry channels failed. Solar eclipses also started to cause the watchdog timer cycle to reset, which switched off the satellite for approximately 15 days. In 2008 solar eclipses became a permanent feature of every orbit, causing the satellite to switch off for about 15 days, probably after only one orbit of transmission. Thus the satellite was not expected to be heard again for any continuous period until 2019, when there will be some eclipse free periods. However, the satellite started transmissions unexpectedly in November 2008. These continued until March, when it was followed by silence until until the recent period of activity. OSCAR-11 transmits on 145.826 MHz., set receiver to NBFM. The satellite has a characteristic sound, rather like raspy slow morse code, sending "di di dah dah dah dah dah dah dah" sent over a period of five seconds. If you are receiving a very weak signal, switch the receiver to CW or SSB. You should hear several sidebands around the carrier frequency and should be able to hear the characteristic 'morse code like' sound on at least one sideband. Please note that you need a clean noise-free signal to decode the signals, and your receiver must be set to NBFM mode, for a decoder to work. If you need to know what OSCAR-11 sounds like, there is an audio clip on my website www.g3cwv.co.uk/ which may be useful for identification and as a test signal for decoding. 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 real time clock is showing a large accumulated error, but is now incrementing accurately to within a few seconds per month. The day of the month has a bit stuck at 'one' so the day of the month may show an error of +40 days for some dates. The time display has switched into 12 hour mode. Unfortunately, there is no AM/PM indicator, since the time display format was designed for 24 hour mode. 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. 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 have shown this to be 20.7 days, ie. 10.3 day s ON followed by 10.4 days 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 last telemetry received from the satellite is available for download. The website contains an archive of news & telemetry data which is updated from time to time. 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.g3cwv.co.uk .

Fwd: AMSAT at the NASM (Hispanic Heritage Month) - October 16, 2010, last call for volunteers
by Samudra Haque 04 Oct '10

04 Oct '10

Hello all, please note the upcoming special event on the 16th of October, 2010. I would like to remind AMSAT-NA and AMSAT-DC members I am still taking volunteers for this event. Please contact me directly for details, and any co-ordination for travel to NASM, or if you have any items to contribute for the day, I can arrange for a pickup. Samudra Haque, N3RDX & S21X Alexandria, VA 22310 (202) 812-3325 samudra.haque(a)gmail.com ---------- Forwarded message ---------- From: Samudra Haque <samudra.haque(a)gmail.com> Date: Tue, Aug 24, 2010 at 3:55 PM Subject: AMSAT at the NASM (Hispanic Heritage Month) - October 16, 2010, First call for volunteers To: Amsat-bb <amsat-bb(a)amsat.org> Hello AMSAT-NA and others, if you are interested in volunteering for AMSAT outreach activities, please consider the following event that is being organized by the National Air and Space Museum in Washington, DC. The last event at the NASM was Space Day, which included a live ARISS contact and AMSAT display stands with a variety of equipment and presentations. Event: Hispanic Heritage Month Family day—Argentina in Air and Space Location: National Air and Space Museum Date: Saturday, October 16, 2010 Time: 10 AM – 3 PM I am volunteering to organize AMSAT's participation for the event. Please contact me through e-mail if you are interested and able to participate in any form. I will need to know: * Can you volunteer any exhibition/display resources (pictures, posters, etc.) ? * Can you volunteer your time on October 16, 2010 for any portion? * Can you provide any presentation materials relevant to Argentina in Air and Space? * Will you require transportation? etc. etc. Additional info from NASM: NASM is looking for AMSAT members who would be interested in talking to the visitors about satellites. Because the focus of the day is Argentina, we are particularly interested in people with expertise in Argentinean satellites. Bonus points for members how can discuss Pehuensat-1 because Pablo de Leon, who was the payload manager, will be a featured speaker at the event. Expectations: AMSAT members would set-up tables with equipment, posters, and other items of interest to visitors. These tables would be staffed throughout the day by AMSAT members. You are welcome to volunteer for a couple of hours or the whole day. Free parking will be provided all, and lunch will be provided for people who volunteer the whole day. This event will celebrate both the centennial and bicentennial of Argentina. For the centennial celebration we will focus on Jorge Newberry and lighter than air. For the bicentennial (which is this year) the focus will be on Argentina’s accomplishments in space. The linchpin of this portion of the program will be Pablo de Leon. He has been involved with a number of projects for the NASA and CONAE. Based on his accomplishments a special feature will focus on space suit design, development and production—ILC Dover has agreed to bring some of the people who make the actual suits. I have already outlined some of his involvement in satellites. In addition to that, CONAE is sending a large model of the SAC-D satellite and I am hopeful to have some the Aquarius team involved as well.
