[Hallicrafters] Questions for OLD-timers (Hams)

[Waldo Magnuson]

I'm interested in your answers/comments on the following topics.

1.  I've read that the Post Office Technical Branch was at one time 
(1920s, 1930s?) responsible for enforcement of amateur radio practice 
(operating frequency, power output, etc.). Does anyone know if that was 
the case?  The Federal Radio Commission came into being in 1927, later 
to become the FCC in 1934.

2.  At one time Hams were required to keep an accurate log of every 
contact.  Was that true and is it still required but not practiced?

3.  In the 1940s and 1950s I think the amateur license application 
required you to list how the station frequency was to be monitored 
(measured).  Was that true?  When did that requirement get replaced 
with "Operated in accordance with good engineering practice"?  I 
suspect most operators now rely on the crystals in the transmitters 
or/and a crystal calibrator to remain in the band.  Crystal use started 
in 1934.

I'm trying to put together an article and the above questions/thoughts 
have a bearing in the article content.

Thanks.
