[amsat-bb] OSCAR-11 Report
OSCAR-11 REPORT 27 April 2011 This report covers the period from 02 March to 27 April 2011 . During this time the satellite has been heard from 03 to 13 March, 24 March to 03 April, 13 April to 23 April 2011. It is expected to switch-on again 04 May until 14 May. Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames. Transmissions are controlled by the watchdog timer, which has a 20.7 day cycle time, 10.35 days on, 10,35 days off. Solar eclipses occur during every orbit, when signals are weaker. This indicates that there is still some capacity remaining in the battery. The on-board clock is now very stable. It gained 12 seconds during during the current reporting period. This is comparable with its accuracy when the satellite was fully operational, when 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 VHF beacon frequency is 145.826 MHz. AFSK FM ASCII Telemetry Reception reports have been received from Horatio CX8AF, Jerry WB5LHD and Stefano IZ1GRJ. Many thanks. At the present time, while OSCAR-11 is operating in a predictable way, I no longer need direct reports or files by e-mail. However, could all listeners continue to enter their reports on the general satellite status website http://oscar.dcarr.org/index.php. This is a very convenient and easy to use facility, which shows the current status of all the amateur satellites, and is of use to everyone. Reports around the expected times of switch-on and switch-off are of special interest, especially for times 12:00 - 17:00 and 22:00 - 07:00 UTC, to when the satellite is out-of-range in the UK. A longer version of this report report is available on my website, and new listeners to OSCAR-11 should read this for further information. The URL is www.g3cwv.co.uk/oscar11.htm . This page contains a links to the longer report, a short audio clip to help you identify the satellite and a file of the last telemetry received. The website also contains an archive of news telemetry data which is updated from time to time, and details about using a soundcard or hardware demodulators for data capture. There is also software for capturing data, and decoding ASCII telemetry. If you place this bulletin on a terrestrial packet network, please use the bulletin identifier $BID:U2RPT155.CWV, to prevent duplication. 73 Clive G3CWV xx...@amsat.org (please replace the x's by g3cwv) ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] SO-50 question

[amsat-bb] Re: SO-50 question
About 700km above the earth, or 435 miles. Your range will vary, of course (it's 700km above you only during a 90 pass! other times, it's more...) That's less than the distance between Savannah, GA and Miami, FL! 73, Mark N8MH On Thu, Apr 28, 2011 at 9:21 AM, Ronald Nutter rnut...@networkref.com wrote: I should know the answer to this one.

[amsat-bb] Re: Icom D-Star
One of the ways to look at the voice codec is as a capacitor, amplifier or some other component of you circuit design. Sure, it's single source, but if you are careful about how you put it in, you can provide a switched circuit, daughter board or some other path to alternative codecs. It just depends on what your real desire is, and how complicated you want to make your system. I.e; if you are worried about designing a system with a single source codec, don't design it that way. Sure we have open systems, but we also have single source systems, like windows. Many many people are content with saying, if it doesn't run on windows, I'm not interested in it because that's all they've ever used. Or, even worse, I'm not supporting anything but windows because I don't know how to do that on Linux, or Mac or B-OS or... Look at what is happening with Apple. Every quarter they are reporting explosive growth in Mac sales (2x from same period a year ago for this past quarter) and other items. That is completely single source stuff, but you can run windows or linux on a mac. People are finding value in the package they see and are switching horses so to speak. Everywhere in life we get to make choices, measure the good vs bad with our own skills and experiences etc. In the end, our choices and experiences are controlled if not limited by any decision we make. Don't think about this from the single vendor perspective. Think about this from the what can I do with this technology perspective that is that heart of HAM radio experimentation. Clearly ICOM is now understanding that if you can't access a repeater with digital data services, then paying 2x the cost of an analog rig of the same caliber just doesn't make sense to most people. Also, as this discussion has illustrated, some of us have no interest in the whole of digital coded data and voice.

There are many codecs available out there today that don't require purchasing a license to use. The biggest problem right now is that D-Star isn't backward compatible or you could implement one of those freely-licensed codecs now and let people design their own implementation. Tell that to the likes of G4KLX, KI4LKF, the ircDDB team, PA4YBR, the designers and builders of various GMSK modems, and even AA4RC and Moe, who designed the DV Dongle hardware (not to mention those who are building their own Dongles). Sure, the codec is proprietary, but there are implementations available, from a bare chip (at around $20) to the DV Dongle for people to play with. And there's a LOT of tinkering to be done without even decoding the audio, as many of the above people can attest to first hand. As far as I'm concerned, this argument is a furphy. There are open source implementations for just about everything else - gateways, repeaters, GMSK modem (using a soundcard), routing advertisements (ircDDB), everything except DPlus (though there is an open source functional equivalent - DExtra). 73 de VK3JED / VK3IRL http://vkradio.com ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: SO-50 question
Hi Ron, Use a tracking program to help explain this. The altitude/height for SO-59 varies between 615-704 km above the earth because of the orbit. The range depends upon the maximum elevation that the satellite reaches on each pass. At the beginning of a pass for SO-50 the range is around 3000km and for each pass the range will decrease until it is at TCA. The range at a 90 degree pass over a QTH will be the same as the altitude. The signal will have quite a bit of path loss difference due to the large (3000 to 700 km) distances experienced during a pass. Generally the beginning and ending signal will be around 3000km and the signal at TCA depends upon the maximum elevation for that pass.

In attempting to make a list of ham equipment I have owned in the past, I recalled with fondness a surplus cavity bandpass filter I used with OSCAR 10. At the time, in the 1980s, these were cheap and quite popular with satellite users. I was living in downtown New Orleans, and the filter, which was mounted at the antenna next to the mast-mounted preamp, totally eliminated my problems with birdies and local cross-mod. Does anyone recall this filter and perhaps have a photo or info? 73, Bill NZ5N Hi Bill, NZ5N I suspect that it was a surplus Filter Band Pass F-204/U built for the U.S. Army by Budd Lewyt Electronics. It is a double cavity filter about 10 long. The cavities are two in series and the diameter of each gold plated cavity is 2 while the front panel is blue color 6 wide and 2.5 high with two tuning black knobs with calibrated dials in channel numbars. In the bach panel there are two N connectors for input and output. Originally a set of six or eight cavities was placed into a rack to cover from about 100 MHz to about 450 MHz. I have two of them with the original frequency range 374 to 404 MHz and it was necessary for me to short it by a few millimeters on a milling machine to get them resonate to 436 MHz for the uplink on OSCAR-10 and OSCAR-13 By the way I was never able to find in the surplus market the model that resonates to 145 MHz because they were very popular and were used for FM repeaters but they are cheap and all of them have the same 10 lenght so that it is easy to mount it at the antenna next to the mast-mounted preamplifier. If I am correct please let me know. Tanks 73 de i8CVS Domenico ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Hi John! There are 75 QSL cards in the mail now from Hector, CO6CBF. Just two of them are in envelopes received by Hector, however, he reports that since that time, he has received several envelopes from the US. My CO6CBF QSL card and SASE arrived at my PO box today. The envelope appeared to have made the round-trip intact, going first to Cuba and then for the return trip through Miami and Cleveland. Many thanks to John for being the maildrop to get the cards distributed, and - of course - to Hector for being there for the QSO and then sending the QSL cards with his friend to the US. 73!

[amsat-bb] Icom D-Star -to- A-STAR Gateway
Tell that to the likes of G4KLX, KI4LKF, the ircDDB team, PA4YBR, the designers and builders of various GMSK modems, and even AA4RC and Moe, who designed the DV Dongle hardware... The real thing that would explode D-star onto the world stage would be if they implemented an A-STAR gateway into the D-STAR system. That is a means to gateway to existing analog users with existing radios. Then everyone everywhere could participate in callsign-to-callsign voice contact just like D-star. The A-Star gateway does this. It uses the built-in (APRS) digital signaling in any of the 8 current models of Kenwood and Yaesu APRS radios to provide the seamless interface. The APRS radios can be configured to send out their CALLSIGN with each release of PTT, thus giving the automatic callsign identification (Like Dstar). Further, APRS radio users can signal who they want to talk to by simply entering an APRS message to the intended callsign target. This way, the A-STAR gateway provides the same end-user-to-end-user-by callsign VOICE calling as Dstar. On the D-star side of the gatway, all the A-STAR gateways look like just another D-star repeater. But on the Analog side of the A-STAR gateway, it looks like a normal Analog repeater. BUT, the analog repeater is listening for the PTT burst with the callsign ID's. And the A-star gateway interprets incoming callsign message requests as requests for a voice link and sets it up as if it was a D-star system. See how. www.aprs.org/avrs.html This is all part of the Automatic Voice Relay Network concept that ties together all linked voice systems into a universal-by-callsign VOIP system. It is where APRS has been headed since 2001. And it is why all the recent radios from Kenwood and Yaesu can include their operating frequency in their ID packet and why they can also QSY to a commanded frequency on an incoming message with the press of a single button. We just need someone to write the A-star gateway software into the D-star network. Bob, WB4APR ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

That is a means to gateway to existing analog users with existing radios. Then everyone everywhere could participate in callsign-to-callsign voice contact just like D-star. Bob, you're going to get a LOT of resistance to this from the D-STAR community. The idea has merit, and APRS could provide a data channel for passing routing information. Unfortunately, there's a lot of purists out there in the D-STAR world. You might get more traction for the idea by going to the ircDDB community, where there's a higher proportion of experimenters. Your A-STAR gateway would likely need to be registered with ircDDB (USTRUST/K5TIT certainly wouldn't register it), so it would look like a D-STAR gateway to the network. The more I think about it, the more I think there's something in this. The A-Star gateway does this. It uses the built-in (APRS) digital signaling in any of the 8 current models of Kenwood and Yaesu APRS radios to provide the seamless interface. The APRS radios can be configured to send out their CALLSIGN with each release of PTT, thus giving the automatic callsign identification (Like Dstar). Further, APRS radio users can signal who they want to talk to by simply entering an APRS message to the intended callsign target. Can the message be sent on every key down? i.e. store the message and then program the radio to repeat the same message every time you hit PTT? This is what would be needed to use D-STAR's callsign routing. I noticed there's quite a few APRS capable radios out there now. I was almost tempted to buy one, but that came after knowing I have to watch the budget for the time being. It's on the wish list. This is all part of the Automatic Voice Relay Network concept that ties together all linked voice systems into a universal-by-callsign VOIP system. It is where APRS has been headed since 2001. And it is why all the recent radios from Kenwood and Yaesu can include their operating frequency in their ID packet and why they can also QSY to a commanded frequency on an incoming message with the press of a single button. Unfortunately, in Australia, we will have to keep D-STAR (and any A-STAR gateways would be considered as part of D-STAR for this purpose) separate to IRLP and Echolink, because bridging the two would lead to a very high risk of licence breaches, due to how our regulations work, combined with the bands that the IRLP and Echolink systems are on (A-STAR gateways would be advertised as such and CTCSS access to avoid accidental access by Foundation calls and the legal implications thereof). We just need someone to write the A-star gateway software into the D-star network. I suggest you ask around the ircDDB community, as that's where the software development and home brew gateway efforts are centred, because there's much more room for experimentation there than on K5TIT. The idea is interesting and certainly has merit. 73 de VK3JED / VK3IRL http://vkradio.com ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: Hector CO6CBF EL92
It was great to receive Hector's very nice QSL card in the mail today! I have started uploading my contacts to LOTW for the benefit of those that use it. However, it is of no use to me because: 1) I am not an ARRL member so I am not eligible to apply for their awards. The QSL cards I receive are, themselves, my awards. I have nothing against the ARRL but all the money I have budgeted for amateur radio organizations goes to AMSAT. 2) The internet, email, etc., are great but can't provide the thrill I get when I open my mailbox and find a real, honest-to-goodness QSL card. Yes, I know postage and printing costs money and if I didn't spend the money on postage, paper, and ink, I could afford to donate more to AMSAT. Evidently, many of you agree with me because, to date, I have mailed 423 QSL cards and have received 304. That is a much higher percentage than verifications I have gotten via LOTW. 73, Chuck, KM9U - Original Message - From: David Maciel xe...@prodigy.net.mx To: Grupo Amsat BB amsat-bb@amsat.org Sent: Thursday, April 28, 2011 21:48 Subject: [amsat-bb] Re: Hector CO6CBF EL92 Need to ask something, may be silly to some: - The ARRL can give an account of LoTW for Hector ...? or hector can create ..? is it possible ..? That would be the best solution for him, and also find a QSL manager. Thanks if anyone can answer the first question. if you think I can help in mexico to be a bridge to Hector via airmail I'm ready to help, many years ago sent a box to Cuba for the Cuban Federation of Amateur radio equipment too old, no problem, not if Now everything has changed from Mexico to Cuba.

Hi Chuck! It was great to receive Hector's very nice QSL card in the mail today! I have started uploading my contacts to LOTW for the benefit of those that use it. Great! Thanks for those uploads to LOTW. Evidently, many of you agree with me because, to date, I have mailed 423 QSL cards and have received 304. That is a much higher percentage than verifications I have gotten via LOTW. That might not be entirely correct. LOTW has only been available for VUCC applications for 3 months, and many satellite operators have not bothered with LOTW until that announcement. I do enjoy sending and receiving QSL cards, and have not stopped that even though I am also uploading QSOs to LOTW. More stations are uploading satellite QSOs to LOTW, and now ARRL needs to start processing the VUCC applications it has (among those, my initial satellite VUCC application). 73!
