To: [e-mail]

AO-27:
I worked AO-27 for the first time tonight and noticed something.  Is it
usually full of ragchewers that tie up the satellite like they are on
75 meters?  Sounded like it was their own personal satellite.  Is it on all
the time?  Seemed like I had to key up a few times and then there was the
signal all of a sudden.  It was up to 23 degrees before I finally heard it.

UO-11, UO-15:
What are these birds used for and what modes do they use?  Think I heard
something digital on 145.825 when UO-11 came over but when UO-15 passed,
I heard nothing on 435.120.

AO-21:
Are all transponders active on this?  I only heard a beacon on 145.819
and, of course, the digital repeater.

Thanks es 73

   Your observation of the type of operation on AO-27 is accurate. I used to
   work it from my mobile station, but have had to give it up due to the
   large number of high power base stations with large uplink beams using it
   for passing recipes etc. On the rare occasions when this satellite is
   not cluttered, 4 W talkies with rubber duckies can work each other.

   AO-21 is much worse because it has been around longer. The regulars on
   this one use 40 el uplink beams and 1 KW plus amplifiers. The downlink
   is 145.987 Mhz FM and the uplink is 435.016 Mhz FM.

   For info on the other birds you mightr pick up a copy of "The Satellite
   Experimenters Handbook".

What frequencies were used during the Appollo missions for voice and video?
How long did it take to reach Earth from the Moon?

It was not a trick.  It is a special message that plays twice in a row during
a pass.  BTW, does anyone know the schedule for voice/pre-recorded voice/wefax
on AO-21?  i.e., is there a certain minute that the repeater comes active?

It was spouting all sorts of things to do with the 25th anniversary. I
heard what sounded like fax and packet as well.

Does anyone have a FAQ for the OSCARs?  I would like to work them
but I don't have much literature on them.  Thanks.

If you have a copy, please end it to [e-mail].  Thanks!
