[amsat-bb] Re: ARISSat transponder
Hi Sebastian, I have had similar experiences over the past few days here in Wales ( UK) during the higher daylight passes which now transpire. I was really surprised how strong my downlink was and I only use an ELK antenna ( with tracking ) software. No replies to my calls but I did hear others keying / tuning on to my operating frequency. Strange though as I also know of reports from others whom had no response. Perhaps with the rapid changes that have transpired one has to just be lucky with conditions being concident. Will also keep on trying - Good Luck to all and pleased to see that at least the transponder has benn functional. Ken Eaton GW1FKY Amsat -UK Amsat NA ___ Sent via AMSAT-BB@amsat.org.

Yes I also understand that it is not an Amateur Satellite but an Educational Satellite operating with an experimental license on 435.750 MHz. The website at http://www.gaussteam.com/index.php?option=com_contentview=articleid=94:edusat-english-versioncatid=35:edusaItemid=195 Appears to list an Uplink as being in 145 MHz. I do not know if the command uplink station in Rome is operating in 145 MHz using an Amateur or Experimental license. 73 Trevor M5AKA --- On Tue, 30/8/11, Gi.

Ok, So it's not an amateur sat. It is also not an amateur experiment,so why is it using amateur frequencies? I have read and reread the regulations governing the use of amateur frequencies and all I can find is a vague definition to the effect that the operators should be licensed amateur operators! What is so different that the amateur satellite service can use any non disclosed frequencies and modulation techniques to any other secret communication systems that are expressly prohibited by the universal amateur regulations?

It's not even primarily ours, Hams are secondary users. As well as radiolocation, it's available for Earth Exploration Satellites. Perhaps that is what this satellite qualifies as.

[amsat-bb] ARISSat RF and audio recordings
Hi, Very good quality recordings of ARISSAT1 wide band RF signals are available on AMSAT telemetry directory. http://www.amsat.org/amsat/ftp/telemetry/arissat/recordings/ However, the server downloads are very slow probably due to a limited bandwidth. Laurent, F6FVY managed to upload the three files on a ten times faster server. http://dl.free.fr/kMOKtIsK2 http://dl.free.fr/n5dpN5JJx http://dl.free.fr/jXbL1U3Dz These RF stereo audio wav files may be played back and demodulated using any SDR software like HDSDR. AMSAT-DK made available BPSK telemetry audio files already demodulated that may be decoded by ARISSatTLM program. http://www.amsat.dk/oz7sat/sched.php?gs=oz1ktesat=ARISSAT-1status=All These audio files are sampled at48 kHz and include CW andBPSK1000 designed by Phil KA9Q (http://www.ka9q.net/bpsk1000.html). 73 de Bernard, f6bvp ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: ARISSAT-1 TLM Problem
Randy, Make sure you have any audio or DSP filters switched off, IF shift to centre etc. I found the 'tone' control on the FT736 affects the decode (eventually, by accident).. Also I found that I had a dirty contact on the soundcard input to my PC's motherboard! After I fixed some of these things, the decode was okay, mind you I suspect shielded cable would also be better - I'm using twin speaker lead.. :( . Put the CW at the marker (as close as possible and adjust for doppler) in USB mode and you should get some good frames eventually. I've found usually the high elevation passes are reliable, the low ones at 3-5 degrees just don't give me enough of a chance to get telemetry sometimes. The soundcard is usually part of the issue also. My old P-4 shuttle mainboard AC97 codec style soundcard I think only samples at 48KHz or something and uses software drivers to pretend the sampling is at other rates - a proper PCI soundblaster style card or high quality SDR style soundcard would probably work better. At some stage I might try a better PC but for now it works some of the time straight from the headphone socket to line-in on the soundcard. 73 James VK6FJA On 30/08/2011 2:00 AM, Mark L. Hammond wrote: Hi Randy, Some people have reported that some types of soundcard interfaces don't work with this telemetry format. Some reports are even from reliable sources ;) All kidding aside---where are you getting audio out of the radio; what is the path to the sound card (straight wire? some type of interface, either homebrew or assembled?); and what sound card input are you using?

[amsat-bb] Antenna advice please
Hi, At a new QTH and setting up a dual band quad antenna for 2m and 70cm. I plan to make the 70cms antenna,the vertically polarised one, 2m horizontal, as I believe this is the normal arrangement. If anyone has practical experience that goes against this assumption I would be interested, either direct on on the bb. I don't have polar phasers, switchable delay lines or anything else its just a straight choice, which one goes vertical. They are on the same boom so I suppose I could go slant for both ? Main activity here will be phone, VO-52, AO-51, FO-29 plus satellite telemetry from cubesats etc. Thanks in advance John G7HIA ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Good ARISSat-1 reception with rubber ducky in Eastern Canada
I was visiting FN95 on my vacation; beautiful hilltop with about nearly 360 degree visibility. I first caught a 30-degree elevation using my F6A with stock rubber ducky. I had to twist it around a bit to find the right best orientation (horizontal this time) but I got a nice signal the entire pass. I hope I have recorded some SSTV that I can decode once I get back home. That will be cool! Next orbit (about 23:58Z Aug 29) it went directly overhead (or close). This time I happened to hit the greeting in English, which was clearly audible, although I did not get as much SSTV. I probably wasn't tweaking the doppler enough or getting the orientation right. Bonus: ISS came over 5 minutes later and I got to ooh and aaah our friends. Now that I have a few things that work, I can eliminate some of my sources of trouble at the home QTH, and hopefully get the signal back where I have the decoding software etc set up! Whoo-hoo! This is fun! And the telemetry sounds like the solar panels are holding up well even if the battery did not! Burns, W2BFJ ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.
