Scans from old radio books
 

I inherited a number of old radio books. They are from 1917 to around
1960. They are so interesting I decided to send out some scans of some
pages out to friends. I thought if anyone wants to be put on my list I
could email out to them as well.
Just send an email to and include "radio scans"
in the subject line. A recent one that went out was a diagram of a 1917
spark gap transmitter.
