While rummaging through an "antique" store, my local daughter found, and got
for me, a Packard-Bell Shortwave Log and Tuning Guide. Published in 1939, the
thin little booklet cost a princely (then) sum of fifty cents -- equivalent to
about $10 now.

Anyhow, it was published primarily for owners of P-B radios that had
push-button settings. It also discussed how to use the tuning eye on models so
equipped as well as the usual "how to" in tuning in shortwave stations.

It lists all the active SW stations in the world (not many then) and their
frequencies and schedules, as well as US AM BC stations running 50 kW or more
(some current 50 kW stations aren't listed) and Western US AM BC stations.

She said there were also some radio magazines from the 1920s, 1930s, and 1940s.
I told, not asked, her to go back and get them for me. G
