> ... how do you know they were mexicans? I was afraid I would get into trouble for that... > Or was it because they were doing work that > [others] won't do because it's too hard? Actually, you are right, Because we all suspect that normally a government crew wouldn't be doing any work. They would be sitting around on break doing nothing but complaining waiting on someone else to do it. But the contractors (usually with mexican labor) actually drive up, do the job, and are gone. So I did not mean to sound prejudiced, except that when I used the word mexicans, I mean "something is about to get done, and fast" so watch out... In this case, they had the tree replaced in under an hour and left no trace... I was worried my transmitter would go to the dump with the dead tree.

Packet Sats
by John Marranca, Jr 25 Sep '07

25 Sep '07

Sil, et al: Thank you for the help. I see that a terminal program was necessary to UPLINK. Got it. I downloaded the UISS, and it seems VERY user friendly. I am actually excited to try this mode. I have noticed, as least as far as the ISS is concerned, that the signal is exceptionally strong for a "satellite". Even when I'm off frequency a bit, Packet Engine Pro can still copy the downlink. Finally, I just want to pass along my experience this morning. I wake up every morning at 0600 EST. As I was walking (rather...hobbling) down my stairs, I heard Orbitron give the beep-tone...letting me know that a sat was near. So, I sat in my chair, and turned the Vista Machine's monitor on. And...it was the ISS. Coming for an ALMOST 90 degree pass. So...hooked up the audio cable to the headphone jack....and copied the packet bursts. At almost 90....I ran outside, and I could see it fly across the sky, as the sun was coming up. THAT was really cool. Makes me proud that I have tried something new in Ham Radio that is SO MUCH fun. 73s all.

Set my ICOM 910H and Wimo 70cm helix to my TCA for 437 MHz CW; and at 20:07:13 utc (5 mins late on nominal keps) on 436.994.8 MHz detected with Spectran a weak intermittent 2kHZ tone: but unfortunately moved UP in audio frequency to 2k4, indicating local qrm, not doppler.

[Fwd: Re: Helping track YES2]

Hi, There may be part of the YES2 / MASS project still operating, please read the following. Any help would be appreciated. 73 Dave G4DPZ -------- Original Message -------- Subject: Re: Helping track YES2 Date: Tue, 25 Sep 2007 19:08:21 +0200 From: Roger.Walker(a)esa.int To: Neil.Melville(a)esa.int CC: Age-Raymond.Riise(a)esa.int, A.R.Bonnema(a)isispace.nl, david.johnson(a)blackpepper.co.uk, Fabio.De.Pascale(a)esa.int, gb4fun(a)rsgb.org.uk, g.shirville(a)btinternet.com, howard(a)howardlong.com, kk(a)karlos.dk, kresten(a)control.aau.dk, "Ubbels, W-J." <W.J.Ubbels(a)tudelft.nl>, fabio(a)fabiolinux.com Neil, The YES2 project very much appreciates the efforts of the GENSO community in its attempts to search for and track MASS. We estimate that the battery life would allow for about 10 hours of continuous telemetry transmission, so by now we can assume that MASS is no longer functioning. HOWEVER, the Fotino capsule should also be broadcasting data in orbit for the next 4-5 days, so the YES2 project would like to request the assistance of the GENSO community to search for and track Fotino. We estimate the Fotino orbit to be similar to Foton-M3 but with a lower perigee altitude of 230 km. Hence, we expect Fotino to be ahead of Foton-M3 in the ground track due to the slightly increased orbital period. Rough estimations are for Fotino to advance ahead of Foton-M3 by about 1 minute per orbit since capsule release on 07:22 Zulu today. Fotino should be transmitting data bursts of 312 bits (lasting 35 milliseconds) every 5 seconds at a frequency of 437 MHz (frequency separation 26 kHz). Every data burst starts with a sync word EB 90 (hex) and looks something like: EB 90 XX XX XX C0 00 00 00 00 00 00 00 00 00 00 00 00 XX XX XX XX XX XX XX XX XX XX XX XX XX XX RR RR where XX bytes are not constant and the 2 last bytes (RR) the CRC checksum of the previous 296 bits of data. Data encoding is FSK, Manchester code. Any help from GENSO in finding Fotino would be greatly appreciated.

So perhaps the battery is already dead, or the tether drag has moved the orbit enough to confuse us. By the next pass the battery will almost certainly be depleted, so I think there is little point in any of you tracking it further. Thank you very much for your help on this. I know that the project team appreciate it. You can track the further status of YES2 on the ESA website: http://www.esa.int/esaCP/SEMBBBC1S6F_index_0.html And also on the project website: http://www.yes2.info/ Kresten, thanks for being so quick off the mark. Abe and Wouter, reliable as ever - you'd started before I even called... Carlos, a star, thanks. I'm well aware that I still owe you presentation material - I haven't been in ESTEC for more than 5 mins since the colloquium, but I will be soon. Howard, Dave and Graham, sorry for disturbing you when you have other pressing non-ham related things to attend to. It was anyway a nice demonstration of the GENSO community and what we can do. I will send management a mail to that effect. I think >=3 stations with an hours notice is pretty good! If only it were all automated already... Many thanks again to all for trying. Cheers, Neil ___________________________________

Microwave link demos (and strange things)
by Robert Bruninga 25 Sep '07

25 Sep '07

Strange things happen... Was giving a satellite lab where we put two tiny "labsats" (spysats) with 2.4 GHz cameras about 1/4 and 3/4 miles away and then use a dipole with and without an 18" dish to show gain and the difference in path loss. See the set-up in the right hand photo at the top of this page: http://www.ew.usna.edu/~bruninga/ea467.html My technician placed the cameras out at 7 AM before class (both are across bodies of water, so the access distance is much greater than the line of sight path). I was giving the demo for the first group of Midshipmen and while looking at the image from the one camera, we noticed it moving and then saw a face. Looked out across the water (on the point of land right behind the dish in the photo) and saw a truck load of mexicans closely inspecting the camera. We were sure a full scale security alert would follow, because the string of "D" cell batteries inside a PVC pipe strapped to a dead tree sure looks like a pipe bomb. Then we noticed something even worse. The truck they were in was carrying a NEW tree! Fortunately, as everyone who works on a government facility knows, the diggers and the fillers are never the same crew. They tossed the new tree off the truck and drove away. SO my technician madly raced over to move the camera, while I madly scurried inside to call the local security to put out any brush fires... Fortunately, we got the camera moved to a nearby light pole before the fillers got there and replaced the tree. Second lab period began, new tree in place as if nothing had happened. No security drill either.. The academy does things like that. Complete flower beds replaced overnight so that there are no dead flowers and there is always something in bloom. Oh, and no wonder all the trees are in good health... If it ain't, then it is replaced! I was sure I was going to be spending the day chasing a landscaping crew to the nearby landfill to retrieve my camera and other goodies... Anyway, these little $75 cameras at 2.4 GHz are a great way to bring microwaves and small dishes into the classroom. Just be careful where you put them. Oh, and plan on seeing LOTS of intereference from LANS. For clear links, choose some of the $75 wireless cameras on 1.2 GHz which don't compete with LANS. But I think the FCC has cut off the supply of these coming in from China... Bob, WB4APR
