|Space Shuttle Atlantis - Sonic Boom heard over Sherwood, Arkansas and recorded by Aaron George Bailey
at 8:15AM May 24,1997 - In advance I learned of the flyover and I was waiting with a recorder rolling.
|Mir - transmitting FM Voice air-to-ground on 143.625 MHz - Early in the morning, Mir is still in darkness as it
streaks across the southwest United States. NASA astronaut David Wolf cannot establish solid contact
with the Ground but he continues to comment, about being North of Whites Sands (New Mexico Test
Range), and then he talks about the city lights of Texas. This was received by Aaron George Bailey on Nov.
28, 1997 using an AR-3000 Receiver and a 100 MHz Discone.
|Sputnik Replica - transmitted a Beeping Signal on 145.820 MHz to the delight of Radio Amateurs around the
world. It was a one third scale model of Sputnik-1 and it was built by Russian and French High School
students. During a spacewalk from Mir, a Cosmonaut tossed it into a new orbit, on Nov. 3, 1997, the 40
anniversary of the Sputnik-2 launch. I received these signals on Nov. 9, 1997. Gear used- AR-3000 +
Discone. Listen to the rapid change of the signal tone, called the Doppler Shift, indicating its nearest
approach to my location.
|Salyut-6/Soyuz-35 transmitting Downlink on a frequency of 121.750 Mhz -FM Voice Mode - Mission Control
in Star City near Moscow, can be heard in the background as it is being Uplinked through a tracking / relay
ship, to Salyut-6. This uplink was a 2nd frequency, different from the 121.750 Salyut-6 downlink. This is an
example of DUPLEX radio communications which Salyut-6 used most of the time. These signals were
received on the morning of May 13, 1980 by Aaron George Bailey. This was orbit #15033 for the Salyut-6
orbiting complex. The Antenna used was a 121.750 MHz Quagi, pointed NE.
