IO-26 heard ?
by Mineo Wakita 26 Nov '06

26 Nov '06

I heard the sound like IO-26 as 1200bps USB, at 435.790MHz +/- 10kHz. Please confirm anyone it in this frequency. --------------------------------------------- Name: Mineo Wakita / JE9PEL, JAMSAT member Mail: ei7m-wkt(a)asahi-net.or.jp URL : http://www.ne.jp/asahi/hamradio/je9pel/ QTH : Yokohama Japan, GL:pm95tj Date: Nov 26, 2006 ---------------------------------------------

Need SatPC32 Doppler file
by Michael Hatzakis, Jr MD 26 Nov '06

26 Nov '06

I've manage to mangle the Doppler.sqf file in SatPC32 beyond recognition and not sure how to extract the files out of the install disk, does someone have a virgin copy or even a well edited version I can use? Or, instructions on how to extract the original ? Michael

Re: New Macs

I'm having a very positive experience with an Intel Core 2 Duo MacBook Pro which I've had for a couple of weeks. All the Virtual Machine (VM) stuff 'just works' under Parallels Desktop (www.parallels.com). It really is a universal run time platform when special hardware peripherals are not a factor. Parallels is a third-party app that lets you create and maintain VMs containing guest OSes, and to selectively connect VM peripherals to the host hardware peripherals (or software emulations thereof). I'm running WinXP, Win98, FreeBSD and SuSE Linux on this machine in addition to Mac OS X, and with no appreciable speed penalty in the VMs. In fact the Windows apps seem more responsive than on some new Windows workstations that we have at work. Now I can run my obsolete apps, ARRL Windows based apps, and my favorite Mac OS X logger and Sat software on the one platform. I'm running MacDoppler Carbon on OS X with rig control USB-Serial adaptor (2303 chipset) to a Kenwood TS-2000. That is all seamless. For that reason have no Windows Sat programs on the system, but on the strength of your post I thought I'd at least see if could connect the Windows COM port to see through the USB-Serial adaptor to external hardware. I can confirm that it works. In addition to Parallels, you need a small freeware app SerialClient from http://eudyptes.com/SerialClient.php to hook the USB device to a temporary file. Parallels then connects that file to the COM port that Windows sees. Windows thinks it has standard COM hardware. I was able to connect to terminal configuration on my Sat Trak IV from Windows Hyperterminal. A nice little side benefit is that SerialClient gives you a real time view of the serial streams for debugging. I'd imagine (hope) there will be similar solutions for the parallel port using USB-Parallel adaptor. Hope this helps, -Nick VK2ZTY >From: Richard Lawn <rlawn(a)uarts.edu> >Date: 25 November 2006 01:00:39 >To: <amsat-bb(a)amsat.org> >Subject: [amsat-bb] New Macs > > >Anyone tried using the new Intel based Mac computers to run PC Sat programs >such as SatPC32 and Nova?

FO-29 Cw Telemetry
by john heath 25 Nov '06

25 Nov '06

Thanks Mineo for the new decoder for FO-29. Works fine. If you are new to copying the CW beacon on FO-29 try some low elevation passes. The rate of Dopler shift will be less so its easier to keep on frequency with Hamscope or similar. You can also check the AFC box in Hamscope which helps. The soundcard decoder CWGet works well too. Telemetry can be fun, we run it as a demo for visitors at the National Space Centre in Leicester. See the solar panel current change and the temperatures rise as the satellites come out of eclipse. 73 John G7HIA

Give FO-29 TLM a try
by Gould Smith 25 Nov '06

25 Nov '06

FO-29 has a strong CW signal sending telemetry(TLM). The beacon transmits on 435.795 MHz, you should find the signal about 435.805 and it will decrease about 20 kHz during the pass. If you are not CW guy, no worries mate. I captured this data using Hamscope, it does a great job. Set the center freq about 1000 Hz, and keep the signal centered on that dotted line. You can save the data in hamscope, edit any incomplete lines out using notepad. Mineo Wakita, JE9PEL has a nice suite of FO-29 CW decoding and display programs on his web site. Download and give them a try. http://www.ne.jp/asahi/hamradio/je9pel/fo29cwts.zip fo29cwts is the simple, one line decode and graphical display http://www.ne.jp/asahi/hamradio/je9pel/#prog fo29cwte is the multiline decode and graphing version FO-29 CW Telemetry data 24 Nov 2006 over North America hi hi a6 03 88 d5 8f f3 05 25 00 24 66 33 73 49 93 8e 9c 86 82 7e 82 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 6d 31 74 49 93 8e 9c 8b 82 7e 82 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 73 2f 75 47 93 8d b2 75 82 7e 81 84 77 hi hi m6 03 88 d5 8f f3 05 25 00 24 78 2d 73 5d 8f 8c 9a 5f 82 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 7c 2f 70 4a 92 8e 9b 7c 82 7e 81 84 76 hi hi a6 03 88 d5 8f f3 05 25 00 24 7e 2f 6f 4b 92 8e 9b 68 82 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 80 2f 6b 4d 91 8d 9b 89 82 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 81 30 66 4f 90 8c 99 8b 82 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 81 30 5d 53 8d 8a 96 6a 82 7e 81 84 76 hi hi a6 03 88 d5 8f f3 05 25 00 24 81 30 5d 53 8c 88 95 5d 82 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 80 31 63 50 8c 87 94 79 83 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 7f 31 6a 4c 8d 89 96 75 83 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 7f 31 6c 4b 8f 8a 97 64 83 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 7e 32 6e 4a 90 8c 99 72 83 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 7e 33 71 4a 92 8e 9b 66 83 7e 81 84 77 hi hi a6 03 88 d5 8f f3 05 25 00 24 7f 34 70 49 91 8d 9a 6f 83 7e 81 84 77 73, Gould, WA4SXM

Re: [Bulk] Re: VU-52 and GO-32
by Michael Hatzakis Jr MD 25 Nov '06

Thanks Tom. I just worked VO-52; a very quiet, strong and stable bird. Too bad I was the only one...! I will check out the WiSP set-up. I have no experience with PACSAT. Just purchased the guide you suggested. I always try to support AMSAT whenever I can. Thanks for your help. Is this basically a BBS with message forwarding, or is there APRS as wel? Michael -----Original Message----- From: Thomas McDaniel [mailto:[email protected]] Sent: Friday, November 24, 2006 9:33 PM To: Michael Hatzakis Jr MD Subject: [Bulk] Re: [amsat-bb] VU-52 and GO-32 Hi Michael, The short answer is that both satellites are very much active. VU-52 is a LEO SSB/CW bird built in India. I haven't used it in a while but it has a very good mode U/V (old mode B) transponder. It is similar to AO-07 in mode B, but AO-07 is in a much higher orbit with longer passes making it a little easier to work. While VU-52 is a little louder but it is a bit quick. SatPC32 and my FT-847 are a good combination for this bird, and I imagine that a TS-2000 or an IC-910 would do equally well with SatPC32. GO-32 is a LEO 9k6 digital BBS satellite that uses PACSAT protocol -- you must use WiSP or something similar to work this bird. I use this one daily and it has been very good the past few weeks. You need to get a copy of the Digital Satellite and Telemetry Guide from AMSAT: http://www.amsat-na.com/item.php?id=100043 This guide has the details for station and WiSP set -up. You normally won't hear this bird, but you should see your S meter come up when you're properly tuned in. 73 Tom n0ntx AMSAT Area Coordinator Colorado Springs, CO ----- Original Message ----- From: "Michael Hatzakis Jr MD" <mail(a)hatzakis.net> To: "'Bob Bruninga '" <bruninga(a)usna.edu>; <AMSAT-BB(a)amsat.org> Sent: Friday, November 24, 2006 9:34 PM Subject: [amsat-bb] VU-52 and GO-32 > Hi guys, > > I just upgraded from Satscape to SatPC32 and very happy about the > transition.

PCSAT-3 Digital Designer Needed
by Bob Bruninga 24 Nov '06

24 Nov '06

Looking for a Digital designer to help with PCSAT-3. PCSAT-3 will hopefully be similar to PCSAT-1 and PCSAT2 including a PSK-31 transponder and of course the usual packet digipeaters.... AND... But it also will have a large surface area that we want to see if we can HEAR micrometeor impacts, and with four microphones and DSP see if we can locate the point of impact. This will require working with a high-end PIC processor that has a DSP code operating at up to 1 MHz sample rate (500 KHz bandwidth), 12 bit resolution, and sensitivity down to 10ths of a millivolt. Supposedly we have a "sofware" guy, but we dont have a digital designer to lay out the 80-pin-PIC processor board, including all the low noise front end to avoid the inevitable noise in the system and a huge amount of FLASH ram to record the data. If it works, and the PIC detects a hit, then not only would it save the data for science purposes, but then we can reply it on the FM downlink as audio for everyone to hear. Expectations are maybe 3 hits per day average? Anyway, if anyone is an excellent digital designer, with time on their hands and is interested in this project, let me know. Thanks Bob, WB4APR
