And confirmed by UHF-Satcom

Lots of things
Aside from getting your Amateur radio license and using our satellites, there are plenty of things you could do with a 10' dish, given the correct feedhorn.
1) Radio Astronomy
2) C/Ka band video feeds (mostly encrypted now)
3) Monitor commercial and US military satellites (some milsats have been taken over by central/south Americans as a free phone system).
4) Get really good satellite weather maps directly from the birds
5) ???
6) Profit! -
Re:Congestion
Yea, I'm clueless too. Try this link specifically.

Re:Congestion
Go here. Read deeply.

Re:Crazy
See http://www.uhf-satcom.com./ They even have sound samples of the pirates in action.

Audio clips of pirates using Milsats
You can hear pirates on some of the clips here (search for 'pirate'). The UHF-Satcom Site has a lot of interesting information on monitoring satellites from UHF and above.

Re:So what's the point in trying to see it, anyway
Hi, yes looking at the spacecraft over a few frames would give you the opportunity to work out the orbit of the s/c. Once the rough orbit is known, the doppler shift can be worked out, and therefore the frequency. MGS has also been heard by radio hams, so its possible that some could watch for a signal. http://www.uhf-satcom.com/mgs/ has some info on the signals detected from MGS earlier this year. Lets hope NASA manages to either image this s/c, or chat to it with one of the rovers.

Re:could you guys fix the hungarian text in the po
"Jó szerencse pölö Charles!" just doesn't make any sense.
Sajnálom/sorry! I submitted the article at 2:30am local time and well my Magyar/Hungarian isn't as good as a native speaker :) Still barátnm will no doubt beat me up about this later on today as I forwarded the slashdot link to her. Incidently I also wished that I had put something along the lines of "claims to be the first nerd in space" as yes I did know about Mark Shuttleworth etc. Still moral of the story don't submit articles when tired!
Anyway please can one of the editors fix the text =)
On a related note for those of you interested in satcom's you may want to checkout the Stereo (Solar TErrestrial RElations Observatory) page on uhf-satcom.com - an interesting website which has featured on previous Slashdot stories that I and others have submitted.
Thanks Richard -

Re:Whick link to click ?
The actual news item got someone else to host the images, so it has a decent chance of surviving
/. But maybe that was the point of all those decoy links.The biography of Paul Marsh is currently Slashdotted.

Further details from the southgate ARC website
The following text is from this article Amateur station hears MRO at 45 million miles on the southgate ARC website:
Amateur station hears MRO at 45 million miles
This week the Mars-Net e-mail list reported that Paul Marsh, an amateur observer, has detected Mars Reconnaissance Orbiter at X band at a range of 45 million miles from Earth.
The MRO transmits on Deep Space Network channel 32 which is 8439.444444 MHz.
By the time that reaches Earth, due to doppler the frequency has dropped to around 8439.031 MHz. The MRO has a 3 meter diameter dish antenna driven by a 100 Watt X-band TWTA to transmit signals to Earth. The signal coming in our direction is of the order of 4.2 mega watts of RF.
The signal was clearly visible in the FFT display of an SDR-14 software radio, and was just audible in SSB bandwidth of a communications receiver. The signal was consistently about 6 to 8 dB above the noise floor.
