Beep, beep, beep, beep, hello there!

[Canis Dirus Leidy]

In preparation for the launch of an artificial satellite, a series of articles was published in the Radio magazine in the summer of 1957. If in the June [ Specified attachment is not available ] issue there was a pure theory (the basics of orbital dynamics, radio wave propagation and the influence of the satellite's own motions on the radio signal), then in the next two there were practical recommendations:

Guide to building a VHF(sic) receiver for tracking Sputnik radio signals at 20 and 40 MHz.


Direction finding add-on. It used the equisignal-zone method: the moment when the satellite crossed the meridian was recorded when the beat of the signal from two directional antennas (switched at frequency of about 300 hertz) became (by ear) equal to zero.


A short extract from the Western press about Vanguard and Minitrack receivers, plus a message from the Academy of Sciences (how to correctly write reports about received Sputnik signals).


Description of the observation technique with a receiver and direction finding add-on, based on the results of field tests (an airplane was used as a signal source).


P.S. I don't think my translation will be much better than Google Translate, so here are the OCRed and spellchecked (I hope) texts of the articles.
