with amateur radio satellites in the article Amateur Satellite Operations. Check it out to learn how easy it is to work low earth orbit satellite with as little as an hand-held radio or similar equipment and only a technician class license. I have made contacts from Massachusetts to Georgia on only my Yeasu VX-8R and an Arrow antenna with 5 watts of power, give it a try!

Beginning Satellite Operations
CollegeARC.com shows the beginner how they can get involved with amateur radio satellites in the article Amateur Satellite Operations. Check it out to learn how easy it is to work low earth orbit satellite with as little as an hand-held radio or similar equipment and only a technician class license. I have made contacts from Massachusetts to Georgia on only my Yeasu VX-8R and an Arrow antenna with 5 watts of power, give it a try!

Quality Space Antennas Take A While To Build
So as a result of building the Turnstile Moxon Rectangle antenna for satellite operations I have learned that constructing a well-built antenna takes a LONG time. I am currently having issues tuning the phasing stub of the 70cm Moxon rectangle. I found I needed to cut the driven elements down about 1 inch due to the center PVC spacing and the end bent portions of the elements were longer than they were supposed to be. A few more hours playing around with the antenna getting the right adjustments should be enough to finish the main part of tuning. Phasing and matching stub lengths truly are crucial to this satellite antenna. The article describing the construction in detail of this antenna will be hosted on www.CollegeARC.com.

Turnstile Moxon Rectangle
Here are some pictures of my turnstile moxon rectangle satellite antenna that I am building.
Thats just the 2m antenna, I will be writing up a larger more in depth article on www.collegearc.com in the near future.

AO-51 Apollo 11 Special Event
So I stayed after work to catch the 6:20PM pass of AO-51 (Amateur OSCAR 51 "Echo") over Massachusetts on July 20, 2009. There is a really nice parking lot which is raised up a bit so with an Arrow satellite antenna I can hear AO-51 with ease from just under 10 degrees above the horizon. I was unaware that the control operator of AO-51 played a continuous recording through the satellite to celebrate the 40th anniversary of the Apollo 11 Mission.
The transmission starts with a clip from John F. Kennedy giving his famous speach of America's mission to go to the moon in 10 years "... not because it is easy, but because it is hard....". It then goes into 30 seconds or so of Niel Armstrong (I think...) stating that the engines of Eagle are off, a few seconds later "the Eagle has landed". Following this is mission control telling them that most of the people in mission controle are "blue" and can finally breath again! A Robot36 encoded SSTV transmission follows.
I tried to record it with my laptop microphone but something wasn't working and its a silent audio clip. Maybe some other bloggers heard these commemorative transmissions or even anyone who is interested please feel free to comment and let me know what you think or experienced!
