RAX-1 is alive

All, Congratulation to the RAX team for this flawless launch. Good signals here in Europe at my first 10 deg pass this morning. RX frequency is about 4 KHz higher with the last published TLE. 73, Mike DK3WN 2010-11-20 04:27:27.080 UTC: [254 Bytes KISS Frame (without CRC)] ctrl: 3 PID: F0 {UI} 235 Payload Bytes from CQ to RAX-1: 1 > AB CD 00 00 03 00 03 EB 00 6B 67 6D B0 6D 38 9D 11 6C 7C 01 21 > 00 00 00 00 00 00 00 5F 04 8F 00 62 09 11 00 00 00 4C 00 B9 41 > 00 2C 00 00 00 00 00 1B 00 3D 00 B8 00 6D 03 6B 07 00 00 FF 61 > FF 06 00 00 00 F8 00 6B 07 D8 06 00 00 00 00 16 00 17 03 15 81 > 00 36 01 00 00 DE C2 05 00 00 00 00 00 99 6A 01 00 00 00 7E 101 > FF 1F 01 4B 00 E8 FB 7C 01 C1 01 38 00 00 00 00 00 FE FF 02 121 > 00 FF FF D4 FC 07 01 B6 FF F4 08 84 0A 28 00 18 06 DC 0A 90 141 > 09 B8 03 20 06 6C 09 60 0A 28 00 24 06 B4 0A D0 09 BC 0A FC 161 > 05 28 00 28 00 28 00 50 06 00 05 C4 09 34 00 FC 05 83 38 FF 181 > FF FF 0E 0E D3 D0 5B 5B 5A 5F 5F 5E 5E 9C CF 3F 00 00 9F 20 201 > FF 41 67 FF 9F 5B CF C8 C7 41 9F 00 00 00 3E A0 0E 00 00 FF 221 > FF FF D2 07 02 FF FF FF FF 05 2B 74 DD DF EE

Please let us know if you have heard FASTRAC? Predicted TLEs
by Sebastian Muñoz 20 Nov '10

20 Nov '10

All, We are very excited about the launch tonight. The current TLEs that we have generated for FASTRAC from the separation vectors is as follows: 1 99999U 10324.08102199 .00000023 00000-0 00000-0 0 00003 2 99999 071.9826 139.9675 0023201 350.7962 235.9222 14.80032549000012 If you hear any of the 1200 baud beacons on 437.345 MHz (FAST1) and 145.825 MHz (FAST2), please let us know (sebastian_munoz(a)mail.utexas.edu). The satellites should be beaconing every 3 minutes. Once we get more precise TLEs we will post them to the website. Thanks a lot for all your support, Sebastian -- Sebastian Muñoz Toro Graduate Research Assistant The University of Texas at Austin Department of Aerospace Engineering and Engineering Mechanics Satellite Design Laboratory email: sebastian_munoz(a)mail.utexas.edu phone: +1 (512) 471-5144 cell: +1 (512) 825-3857

Re: AMSAT-BB Digest, Vol 5, Issue 458

Regarding SSB preamps: I have had both an SP-2000 and SP-7000 in nearly continuous use here in Vermont since 1990. I cannot find any fault with either unit. Both have worked FLAWLESSLY the entire time. Both have been out in the extremes of temperature northern Vermont gets. Some slight discoloration from the sun of the housings. The 2 meter one is not quite so red any more, and the 432 one a paler shade of blue, but that is all. The ARR preamps are excellent as well, but limit you to 160 watts. For most people running a typical satellite station, that would be fine. But if you also want to run V/UHF terrestrial, that may not be enough power handling for you. With a proper sequencer, the SP-2000 will handle 750 watts, and SP-7000 will handle 500, and SSB offers a 1.5 kW 2 meter model for a real rockcrusher station. You get what you pay for. SSB preamps are excellent in all respects for satellite work. I even made my first ten 2 meter EME QSOs with the SP-2000. I had considered using one for my permanent two meter EME station as well, but ended up using a receive only preamp and doing dual feedlines, one for tx and one for rx. 73, Bob W1ICW -- Light travels faster than the speed of sound, this is why some people tend to appear bright, until they decide to speak.

At least my family will find that a much more reasonable time as the actual moment of launch :-) I did not test the kepler set yet, but Bob mentioned ~same Henk ---- G0MRF(a)aol.com schreef: > > Excellent Henk. > > I took a quick look at Kodiak. > > I estimate AOS on orbit 3 around at 5.54 UTC with LOS at 06.06 (That's 4 > hr 30mins after launch) > With orbit 4 at 6hrs 9min after launch. > > Reasonable?? > > David G0MRF > > > > In a message dated 19/11/2010 18:36:35 GMT Standard Time, pa3guo(a)upcmail.nl > writes: > > We will try to stream as much as possible live the audio > of the new set of satellites in the upcoming launch today. > > As a test, we will in the coming hours we will stream HO68 > and other Cubesats. > > http://www.dk3wn.info/p/?page_id=17689 > > -- > Henk, PA3GUO > > > -- Henk, PA3GUO

Anyone have any tips for working the iss? I've heard several passes this week on 145.800 but cannot seem to get thru the pileup. Timing your transmissions seems to be the hardest part. The Tx offset I'm using is -1.31mhz. Any suggestions? John Va3bl Mobile in fn03 Sent from my iPod

Excellent Henk. I took a quick look at Kodiak. I estimate AOS on orbit 3 around at 5.54 UTC with LOS at 06.06 (That's 4 hr 30mins after launch) With orbit 4 at 6hrs 9min after launch. Reasonable??
