[amsat-bb] AO-51 recording 1140Z this morning
Hi Everyone, Still getting used to working the sats and was curious if someone happened to be recording the latest AO-51 pass over North America. For me AOS started at around 1140Z. If you do have a recording, would you mind sharing with me? Curious to see how I sound on the other end. 73 Matt W5LL ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Circular Polarized Antennae
John, LA2QAA That was an interesting message you posted to the -bb this morning. It has many true observations; however there is one serious mistake, an unforgivable error. Quote: . particularly by the newcomers - who apparently, and mistakenly, think that high power is necessary. It's *NOT* . . . nor is an EME class aerial array necessary to work the LEO satellites. Ditto circular polarisation. FACT:polarisation is *ONLY* circular along the boresight of an aerial. Unquote. Your polarization statement is not 100% accurate. Unfortunately most antenna manufacturers, who supply/sell alleged circular polarized antennas do not state that their antennas are circular polarized ONLY along the boresight. They conveniently (?) do not mention that their alleged circular polarized antenna is only circular polarized on boresight, that it is linear polarized at 90 degrees off of boresight and is elliptical polarized of varying ratio at all angles in between! There is however one (and only one that I am aware of) antenna design that is circular polarized over its entire radiation pattern. I refer you to the Q_uadrifilar Helix Antenna_ described by Dr. C.C.Kilgus in IEEE Trans., Vol. AP-16, July 1968, pp. 499-500. Also Bricker, R.W. and Rickert, H.H., in RCA Engineer, Vol.20, No. 5, February/March 1975. There is an excellent review by Walter Maxwell, W2DU, at http://www.IAG.net/~w2du/quadfinal.pdf. When installed pointing to the zenith, the ideal, theoretical Quad Helix has 360 degree coverage in the azimuthal plane and 90 degree coverage in the elevation plane. It is circularly polarized over the entire upper hemisphere. There is no radiation in the lower hemi-sphere; the energy in the lower hemi-sphere of an isotropic radiator is uniformly distributed over the upper hemi-sphere. Hence the gain of an ideal Quad Helix is 3.01 dBi. However you can modify the elevation pattern to give more gain at the horizon and less gain overhead by adjustment of the overall length to diameter ratio. It is possible to adjust this ratio to give constant signal amplitude, at an earth based receiving station, from a satellite in a circular orbit where the range ratio (and hence signal path attenuation) between AOS and the zenith can be significant. This results in a little radiation below the horizon and also avoids the nasty mathematical boundary value problem at the horizon in the ideal case. Quadrifilar Helix antennas are used on many LEO satellites for VHF, UHF, L-band and S-band communication. One of their parameters of interest to satellite builders is that they do NOT require a ground plane provided they are at least a quarter wavelength above the satellite structure. Hence there is negligible critical location requirement and they do not occupy satellite surface area that is required for solar cells. The Quadrifilar Helix antenna is popular with earth based receiving stations for receiving the VHF image data signals from the NOAA weather satellites. Right-hand circular Quad Helix antennas for the 137MHz NOAA weather image signals and 137MHz left-hand circular Quad Helix antennas for receiving the ARGOS programme signals, are available from Spectrum International, Inc. Spectrum also supplies both right-hand and left-hand versions for the 2M and 70cm Amateur radio bands. May we suggest you sprinkle some Grow More fertilizer around the base of your chopped down satellite array every Sunday morning and offer a few words of wisdom while so doing. With a little help and the dregs of Saturday night's Black and Tan, your mini array might grow. Regards, Spectrum. ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

Hi Tom, The LVB Tracker Box designed by Howard Long has a very good reputation and will work well with SatPC32 and other software. It is available in kit form in various options or ready built from Amsat. It also has either a serial port or USB port option. You will need to download a driver for the USB version from the site mentioned in the intructions. Both the Amsat NA and Amsat -UK have published information about its use in their journals and web pages. Good Luck Ken Eaton GW1FKY Amsat -UK Amsat NA ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: New Satellite Downlink?
Bob - Yes, the TRANSIT satellite appears to be designed for a low speed broadcast style service. An Internet entry/access page would permit an ease of UI for the creation of the message to be properly encoded, upilnked and then broadcast on the downlink. Application would require these characteristics: 1. Content would have to be tolerant of no more than 2 changes each day, no stock quotes! Electronic equivalent of the old morning and evening newspaper. What does a locl nespaper provide for content that is still relavent or desired? 2. Content woiuld have to be relavant to amatuer radio or educational / scientific community. 3. Contant needs to be global in nature -- regional or country specific would not appeal to the larger global audience. 4. Should be content that has highest value to a mobile/portable station (think of a lone person in South Pacific - small island or boat: Tom Hanks in Cast Away ). What daily global content wojuld be most useful for them to know?? Assume they have the radio to receive and laptop computer. 5. Due to infrequency, data / information has to be correct the first time -- retractions woudl take one or two days (reducing validity of service content) Some content ideas: a. Daily solar activity/propogation daily bulletins (also sent via ARRL and Internet accessilble) useful to amateur DX community b. Lunar information for Tidal predictions c. TLE of amatuer radio satellites and ISS d. Global short message/bulletin to amateur radio community -- beyong ARRL focus -- more along ITU / global scope e. Astronomical events of note --- northern and southern hemisphere. Plantes visible, rare alignments. f. Special events (scientific, radio, etc.) -- hemispheric or very wide audience Greg w9gb Message: 11 Date: Wed, 25 Aug 2010 12:27:00 -0400 From: Robert Bruninga bruni...@usna.edu Subject: [amsat-bb] New Satellite Downlink? To: amsat-bb@amsat.org Possible new AMSAT Application? We may have access to two old TRANSIT navigation satellites with a 50 baud downlink at 149.985 (and 400 MHz). (presently coming over in the mid afternoon). My problem is, coming up with any meaningful application to use them for communications that would capture the interest of students, hams or volunteers in support of education, public service or emergency comms or just plain fun... The downlink can be heard on an OMNI antenna (though I would suggest a 3/4 wave (55) vertical) and could be decoded by a simple software only application with a sound card. (someone has to write it)... The total useful message capability is about 500 bytes transmitted every 2 minutes (at 50 baud). The uplink is very specialized and can ONLY BE DONE from one (or two) very special command stations. These satellites of course were the original Navy Navigation satellite system (also called OSCARS) and so the message would be in-place of the normal navigation data. SO in a sense, this is a downlink BROADCAST application. Since ham radio is two way, I'm stumped for applications. The total message capability of 500 Bytes can contain one long ARRL bulletin, or 20 APRS position/status reports, or say 20 or so APRS text messages, or say 50 callsign exchanges or maybe even 1 thumbnail image... but what's the application? Even if we allow say, INTERNET link to the command station for anyone to contribute to the twice per-day upload, then everyone's receiver application can receive them... For what? So Im looking for ideas. All I can come up with so far is: 1) ARRL Bulletins? (I don't even know how often ARRL sends bulletins ...) 2) Navy/Army/AF MARS broadcast bulletins ... 3) Internet message in-to-command-upload-to message RF downlink. Two stations do this to each other and it counts as a two-way QSO? 4) ... Every scenario of interest usually begins with the much higher value of UPLINK from the individual field station, not downlink.. Hence I am stumped. HUMMH... Maybe purely educational? If the software can run on any PC with a sound card connected to any scanner... Then every school can use it as a satellite downlink signal of interest.. What kind of thumbnail image can fit in 500 bytes? Send in your picture and get it downlinked on a given day? Etc.. Will need a DSP volunteer to write the sound card decoder.

Printing out words takes the stream of data, does a lookup for each 16-bit quantity, prints that word plus a space, and goes on. A word like communications which is 14 bytes becomes two and is thus a win, but a I and the like is a loss. There could be an escape sequence to provide for the literal transmission of a word not in the 65,000 lookup table, and one could also be added for upper casing of the next word, etc. Doing this, you can transmit 250 words from the lookup table each minute, fairly faster than squirting out raw ASCII. Since you'd likely need a decoder no matter what the transmission is, the 65,000 word table is stored on the client side. Hilarity will probably ensue when someone doesn't update their table after a big change, and gets slightly demented messages till they update their code. Thinking about what to transmit...

Heh. One of the escape sequences could be which language to use, so with the 16-bit scheme here, you could have 64K possible ones to choose from. Just have a 65,000 word table for each one.

With increasing solar activity and new awareness of the possible detrimental effects worldwide of solar storms, combined with the time delay for a solar event to reach Earth (2-3 days) I believe that a possible rebroadcast of Solar Weather ala WWV style, could be a useful educational tool as well as a timely prognostication for radio operations around the world. It would also serve as a town crier type service, warning people worldwide of a potential disruptive event. The standardized resource could be WWV or any other agency willing to provide the info on a daily basis. Solar storm activity reports would not depend on internet access or shortwave receivers but a common scanner and any computer. The mission could be re-tasked after the sunspot peak is well passed.

[amsat-bb] Pakistan flood relief disaster communications
I am forwarding this from the TAPR mailing list in case any Amsat people can help with this effort. Dan Schultz N8FGV The TAPR Office received a telephone inquiry today about the use of Packet Radio for relief efforts in Pakistan. I asked Jeannie to summarize in an email what kind of information or help they were seeking I felt posting to the tapr-announce list would be the easiest way to get the word out. Please contact Jeannie directly if you can help. -- 73, John, W9DDD To recap, we are interested in HAM radio expertise to help us figure out how to enable on-the-ground reports communicated through HAM radio to be compiled into digital maps (e.g., see map created by Ushahidi for Haiti http://haiti.ushahidi.com/, which we fed SMS and Twitter messages) for use by relief organizations. This project is within Crisiscommons.org, ( www.crisiscommons.org) and I am the Silicon Valley city lead. CrisisCommons.org is a volunteer movement of coders for humanitarian relief in natural disasters, and anyone can jump in and contribute any amount of effort that they like. Background information and our current understanding is being recorded at: http://wiki.crisiscommons.org/wiki/HAM_Radio_to_Digital#Self-Register Please encourage any interested parties to jump in and edit the page to help us understand HAM capabilities and technical needs. The goals for defining requirements is to create an open source software stand-alone or add-on software to automate collection of HAM-generated information during natural disasters to a common operating picture. A team is being sent in for a range of CrisisCommons.org projects; if your members could help us communicate with the HAM operators in Pakistan, to get requirements (even by voice), we would love to know more about what they need and how to help. A working group will be running in Silicon Valley this Friday from 5-10pm, and we will have virtual participation. Details at: http://www.eventbrite.com/myevent?eid=538771480 Please feel free to forward this email or advertise this project to your members - the more the merrier. We did send this information out to the contact form for the ARRL. I look forward to any information that you are able to provide! Best, Jeannie -- Jeannie A.

[amsat-bb] SO-50
Was listening for the SO-50 pass @ 22:58Z and didn't hear anything. A check of the Oscar status website reveals that it was active a couple hours ago. Did anyone else hear it during the latest pass? I finally got setup to start recording the birds with my computer and was going to use SO-50 as a test. 73 Matt W5LL ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.
