Hi All,
I see that IK2MKE has reported hearing AO-10, any idea if this is possible?

How strong would it be? Would you pick it up with a 3-ele yagi?
I could hear *something* on 145.810MHz but I'm in the middle of a city so it could be just about anything. I'll try in an hour to see if I can rule out local QRM.

Hi All:
In theory you can work a satellite such as AO-10 (in a Molnyia Orbit) with a Zero Gain antenna system. You just need to be in the right place a the right time. The orbit for AO-10 varies in altitude from 2,560 Miles (4,120 km) to 21,747 Miles (35,000 km ) every day (twice a day).
If the low orbit Dip is close to your House then you will have a 15 –30 minute opening when a Zero Gain antenna system will work for a few minutes (assuming AO-10 is running that day). However as soon as the satellite starts to climb in altitude, you will need to switch over to a higher gain antennas such as a 9-12 dBd system.
In the spring of 1994 I worked AO-13 many times with a pair of Zero Gain Ringo vertical antennas mounted to my Apartment Deck (on a hill, with 200-watt amps). The Secret was timing. I would plan ahead and then wait for the low altitude dip to take place near my apartment in Boston and set aside that time to work people on AO-13. My window of access time was very limited to approximately 15-30 minutes of good access, before the satellite screamed up to higher altitude.
After my new house and tower were installed, I switched over to a full AZ/EL antenna system (22 elements CP on 2 meters (element gain ~10 dBd) and 40 elements (element gain ~14 dBd) on 440 CP, Amps and LMR-600). At the higher altitude’s 21,747 Miles (35,000 km ) I could still work AO-13, however AO-10 was much more difficult.
This Month March 2009 AO-10’s Low dip is in the South Pacific and in the South Indian oceans. Has anyone heard AO-10 recently? I would like to give it a try again.

Note: I prefer to use the terms Element gain because it cuts out the Advertisement hype. Most advertisers add an extra 3-6 points of gain to an antenna. If you ever see an antenna advertised with two letters “dB”, always subtract 3+ to convert it to “dBd”. Or Just count how many Half-wave dipoles are in this antenna and use the chart.

Shuttle Launch Visible Tonight:
If you live along the East Coast of the USA, you maybe able to see the Shuttle Discovery’s launch tonight at 9:20 p.m. (EDT). People in Florida are use to seeing the Shuttle launch, however when the Shuttle is launched at Night, to the International Space Station, the engines can be seen as far north as Maine (conditions permitting).
So tonight, if you have clear skies, try to find a hill that looks SouthEast. The hill will need to be dark with few city and street lights. The shuttle will only be visible for a few minutes to seconds depending on your location. The first two minutes of the launch are the brightest. The Shuttles Solid Rocket boosters will burn for the first two minutes; this will be your best shot as seeing he Shuttle. When the SRB stop, the liquid fuels engines will still be running and generating some visible light. After about 8 minutes after launch the main engines will shut down and so will your light source.
Try to monitor the NASA channel. If you can, have someone at home watch the NASA channel on TV and tell you the countdown by Cell phone.
Boston Weather: Looks like we will be socked in for most of New England. Poor shuttle viewing conditions.
Here is a current link I found that gives a few more details on how to see the shuttle tonight.

Sunset in Boston is at 6:50 p.m. (EDT). This means the skies will still be a little bright.

As always, Mission Audio is available on the IRLP Network on Reflector Channel 9877.
Any IRLP-equipped repeater or station can provide audio by simply dialing it up.
Currently 50 stations are linked in, with more usually around the peak times of launch and landing...

Absolutely Gorgeous view from here in EL88pg, about 150 miles west of the launch pad. I snapped a crappy cell phone picture from the parking lot of where we were having dinner. http://i139.photobucket.com/albums/q305/glasbrenner/PIC-0116.jpg Even with the horrid quality, you can see the darkness, then sunset, then full sun along the exhaust plume. That photo was about a minute after booster separation.
I'm a native Floridian, and seeing a shuttle launch never gets old.

Great pass, we could see STS-119 for over a minute. we could even see the SRB seperation.
i posted a few shots on the spacecam page.

I shot some video from about 30miles west on Hwy 50 (almost due west). I put it up on youtube.
I had the laptop connected to the internet and you can hear the time delayed webcast in the background.

Hi Chris,
do you have some more details? Frequency? Doppler shift, just a carrier? Does antenna pointing fit with AO-10's AZ/EL tracking, etc?
To answer you question: Yes, it is possible.... There have been similar occasions in the past, but I believe the last report is quite a while ago...

Hi all,
just for the history, last night I was listening for about 2 hours the AO-10's beacon-frequency without succes (I re-installed my 9 El Yagi + GasFet preamp - just for that.).
Nothing heard from AO-10.
BTW it was a weak carrier on .809, however without any doppler-effect and remained there "stable" after the..... LOS of Satellite !
So, it is more than obvious that, it iwas just a "manmade" fake signal from my area.
Therefore, it's very easy to think somebody that it has heard the Satellite, however was it the satellite? I wonder also if the last report about AO-10's receiving is confirmed by other peoples.
I was also looking for the original post of IK2MKE, but I can't find it.
Where - when is posted? Any additional info is appreciated.
73, Mak SV1BSX
PS: the last distributed Keplerians of AO-10 are OK ? according to that the AO-10 tonight is "in range" for Europe @ + - 23:20 (from my Location AOS:17:46 Z, TCA 21:30 /AZ=86-EL=21, LOS=23:22Z).

Hi,
I was also listening this morning for a while - with the same results. Nothing that sounds like the carrier of AO-10 or just another satellite. Only very stable QRM signals ...
