,,,, ,, why go through all the trouble of a moderated BB ? i agree Luc goes too far sometimes, and should send replies direct to the poster, not the whole BB. yet, most of his posts are valuable and intelligent. he is a great sat operator from what i see. i do not want to lose his value to this group, nor do i want to see him shunted to ground. if you knew the /real/ story of Jack G/kg6iro the jammer, you would understand. people are people, and sometimes others are just as much as fault (the 435 idiots in LA) for driving a behavior. lack of communication is the reason for most misunderstandings. a great man named King once said: we must live together as brothers (and sisters) or perish together as fools. i apologize for more off topic QRM, i just like to try and see things from a bird's eye view. peace, 73, lets think about Eagle, etc. and quit this foolishness. kf0g cm97 thank you all for the inspiration and leadership.

FO-29 back again ?!?
by SV1BSX 26 Apr '07

26 Apr '07

Hi all, don't "shoot" me if I'm wrong, but I think FO-29 is back! Today 26 April 2006 between 14:10-14:16 UTC (#52.792 orbit) I HEARD (!!!) a continue carrier in FO-29's beacon frequancy ! I was starting to monitor the frequency with a delay, I forgot this time the pass of Satellite (every day I monitored it.) Well, the Sat was over Libya (N.Africa), close to me with 32 Degr. Elevation, in very good range for me. Looking for any activity I tuned my receiver to Beacon frequancy and... what a surprise! I received a strong carrier arround 435.799. The carrier was following the usual doppler-shift, so after 6 mins dropped-down to 435.788 MHz !! That is very normal and confirmed to me the Satellite signal! At this point my QTH has no clear horizon (340 degr.) even if the Satellite was high enough, at 24 degr. Elev. So after 1 min I lost the signal completely. Please keep monitoring the FO-29 and send your reports. May be FO-29 is back again ! 73, Mak SV1BSX __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

I: Re: How much is enough?.
by Francesco Grappi 26 Apr '07

Hi Simon, Thank you for your Ao-51 recording. Of course to have a qso, are required two things ... one station calling and one station answering, if a lot of stations are calling on generic way, is not possible to make a complete qso. Anyway I heard some stations that answered/called to specific call on right way.

Re: Government control has exceeded ...not really.
by Tom Clark, K3IO 26 Apr '07

In this thread, Tom Davis asked > This raises an interesting possibility. The resolution of a 70cm radar is > rather limited for tracking the smaller but still dangerous debris. The Air > Force might propose a new higher frequency radar for this job. Will they? If > they do, would we support their request in Congress? > > Tom The Air Force (USAF), thru MIT Lincoln Labs (LL), have several higher resolution radars at Millstone Hill, northwest of Boston, near the NH border and at the junction of Westford, Tyngsboro and Groton townships. The facilities there support several DoD radar programs, while the "civilian" side of the house is known as the Haystack Observatory (see http://haystack.edu/ for an overview of the facility). The Haystack Observatory activity on the hill is operated by MIT on behalf of NEROC, a consortium of 8 universities (listed at http://haystack.edu/hay/neroc.html). [For full truth in advertising, I have been a member of Haystack's extended family for many years, and I currently serve as an At-Large member of the NEROC Board of Trustees.] At Millstone Hill, the USAF/LL has the 85' "Millstone" dish used as a high power surveillance radar at 1295 MHz. Some interesting info on DoD's various radars (including both Millstone & Haystack) can be found at http://www.ll.mit.edu/news/journal/pdf/vol12_no2/12_2detectsatellitiesplane…; see Figure 26 for an aerial view of the entire facility. Haystack, Millstone and the smaller 60' "Westford" telescope were originally built ~1960 by LL with USAF funding in order to bounce microwave signals off of a belt of passive, resonant dipole "needles" at a time before there were any active communications satellites.Thousands of fine wire needles were embedded in a block of napthalene (think moth balls) so that they would be slowly and uniformly dispersed throughout the orbit. A prototype of the needle dispenser is near the Oscar-1 model at the Udvar-Hazy museum. Yes, there is an in joke involving "needles in a haystack". As an aside, after the AO-10 and -13 launches and motor burns, NORAD's radars had troubles finding our satellites. With some quick round-trip transponder & Doppler measurements, KA9Q & I were able to give Millstone enough orbital data so that could see our spacecraft at 10,000+ km and provide Keplerian elements until NORAD got their act together. At Haystack, there are two antennas. The larger is 37M (120') in diameter and is under a rigid radome (it looks like a HUGE golf ball on top of the hill!). This antenna has been used for a lot of astronomy programs since the early 1960's. Until about 1972, a high-powered 8 GHz transmitter and traveling-wave maser receiver were available for use as a Planetary Radar to obtain spectacular "photos" of the Moon, Mars, Venus and Mercury; Haystack's Lunar images were invaluable to the Apollo astronauts Now it is equipped with a DoD high power 10 GHz radar transmitter with ~1 GHz bandwidth. The 1 GHz bandwidth lets it be used to take a radar "photograph" of satellites with ~20 cm resolution (comparable to a wavelength at the 1 GHz spanned bandwidth). Beside the "big" golf ball is the smaller HAX (Haystack Auxiliary Radar) housed in a smaller golf ball. HAX operates at Ku-band with its own forty-foot antenna, transmitter, RF hardware and receiver, but it shares control and signal and data processing systems with Haystack. HAX, which began operation in 1993, is the first radar to have a signal bandwidth of 2 GHz, which improves the range resolution to ~12 cm. HAX represents a significant advance in radar imaging capability, producing finer and sharper images of satellites than the Haystack. In addition to its DoD sponsored imaging task, HAX has extremely useful in producing detailed information for NASA on the locations, orbits and characteristics of space debris. For some comments on Haystack & HAX tracking debris see http://www.nasa.gov/home/hqnews/1994/94-136.txt and http://web.mit.edu/newsoffice/1995/needle-0208.html. The new "big project" at Haystack is the refurbishment (really, nearly a total rebuild) to upgrade the Radar capabilities to a bandwidth ~10 GHz at P-band (90-100 GHz). Information on HUSIR(Haystack Ultra-wide Satellite Imaging Radar) can be found at http://haystack.edu/obs/haystack/LincolnUpgrade.pdf. With this new radar, images can be made with a few cm resolution. So the answer to Tom's question is definitely YES, it is being done. I leave this question to your own imagination: Why would DoD want cm-level "photos" of stuff in orbit? 73 de Tom, K3IO
