[78-L] Interesting article about remastering and sound restoration for the Mosaic's Artie Shaw Box Set

You answered your own question #1 -  they didn't use a hot stylus, so when 
the wax cooled, the "dog whistle" began.

In remote locations,  a simple box with a couple of light bulbs kept the wax 
blanks warm.  Even before 1930, it would have been rare to hold a recording 
session any place that didn't have some form of electric light .
