How To Build Your Own Sputnik from the BBC

The BBC News web site's Magazine includes an article titled,
optimistically enough, ``How To Build Your Own Sputnik'':
http://news.bbc.co.uk/2/hi/uk_news/magazine/7049002.stm
While the discussion of what goes into a Sputnik box is
interesting and includes details which will not inspire me to actually
build my own, there is one line of exposition which intrigues me:
[ Sputnik ] sent its famous ``beep beep'' radio
signals to earth, altering the transmission to
indicate changes in temperature or a sudden drop
in pressure caused by a puncture in the satellite's
case. And that's about it.
I don't remember hearing of Sputnik being intended to signal
any kind of data like temperature or pressure except by the way that
changes in those conditions might alter the electrical properties of
the equipment inside. It seems like that would have frustrated the
attempts of (United States) people to project its orbit by the Doppler
effect on its transmission as well, but I could easily have forgotten
or missed descriptions of that complication in the past.
Did Sputnik have this bit of data transmission or did author
Paul Rubens get details jumbled?
