SPUTNIK-2 RADIO FREQUENCIES
and errors in printed media from November 4, 1957

BELOW ARE CORRECTIONS FOR ERRORS IN THE ABOVE ARTICLE

The 20.005 mc-(megacycles) was a beeping signal at a wavelength of 15 meters NOT 7.5 meters as shown.
The 40.002 mc-(megacycles) was a steady carrier at a wavelength of 7.5 meters NOT 15 meters as shown.
The 40.002 mc steady carrier is described in the article as a "continuous howl", or more commonly called a
continuous tone, as it would sound like,  when the ground receiver had its
BFO turned on.  The 40.002mc
steady carrier was used for doppler tracking ONLY.  Contrary to the above article, it DID NOT carry
information on the condition of Laika the dog.  Laika's vitals were radioed back to earth by the TRAL D
telemetry on a higher frequency somewhere around 66 MHz.
