The following satellites, launched by the United States and
the Soviet Union, were reported to have beacon and telemetry
transmissions as of October 10, 1962. The satellites are listed
by their code names, according to frequency; because some transmit
on more than one frequency, they appear more than once.

*Signal may be very weak
At least four more satellites are in orbit and may be transmitting.
However, these are so-called "secret" satellites launched by
the U.S. Air Force.

missed our June 1962 article on the NASA-136 converter, we recommend
that you look it up. Easy to construct, this sensitive converter

*Transmits only while satellite is in sunlight - no battery
power
**Transmits only upon command from ground stations - not
during every pass
Satellites of the Soviet Union have telemetry and tracking
transmissions in the 19.990 - 20.010 mc. band. Whenever a Cosmos
series satellite is launched, check Radio Moscow for an announcement
of tracking frequencies. Most Cosmos series satellites re-enter
the atmosphere in 60-90 days. Cosmos 2, 5, and 8 are in orbit
at press time, but do not seem to be transmitting.
