[amsat-bb] 1957

[Burns Fisher]

Lots of interesting stuff in the wikipedia article:
https://en.wikipedia.org/wiki/Sputnik_1#Design but it does not say what the
active device was.  A 1 watt transmitter in 1957?  Must have been tubes, no?

An interesting thing I did not know:  It was filled with nitrogen and used
a fan to cool off the electronics!
