About the Cover:
Before 1912, radio amateurs made up their own unique call signs. Hiram Percy
Maxim's self-assigned call was SNY. Not until the Radio Act of 1912 were the
first licenses issued and Irving Vermilya,1ZE, received “Skill Certificate No. 1.”
The first woman ham we know about was Graynella Packer who worked aboard
the SS Mohawk. In 1913 there were 1,322 licensed Amateur Radio operators
but by 1917 there were about 6,000 licensed radio amateurs listed in the federal
call book.
The 1950’s are considered by some to be the “Golden Age” of Amateur Radio,
but the number of licensed radio amateurs in the US in 1956 was only about
140,000. In the past 40 years, the number of US Amateur Radio operators
has continued to grow.
• December 1971: 285,000
• December 1981: 433,000
• December 1991: 494,000
• December 2001: 683,000
• December 2011: 702,056
We realize that these numbers always included some who were no longer active
in Amateur Radio. However, a recent survey of ARRL members indicates that
more than 80 percent of those responding are active.
