The Anti-Digit Dialing League was a movement that emerged in the United
States in the late 1950s and early 1960s, in response to the growing use of
all-number calling (also known as "digit dialing") for telephone calls. At the
time, most telephone calls were made by dialing a combination of letters and
numbers, which corresponded to the name of the telephone exchange and the number
of the individual phone line. For example, if you wanted to call someone in the
"Broadway" exchange, you would dial "BR" and then the corresponding numbers.
However, with the advent of direct-dial long-distance calling, it became
necessary to use all-number dialing, which was seen by some as an impersonal and
dehumanizing way to communicate. The Anti-Digit Dialing League was formed to
protest against this trend and to advocate for the retention of the traditional
letter-and-number system.
Despite the efforts of the League, all-number dialing eventually became the
standard for telephone calls in the United States and in many other countries
around the world. However, some telephone companies continued to offer
letter-and-number dialing as an option for many years, and some people still use
it today for nostalgic or practical reasons.

 While working on an
update to my
RF Cafe Espresso Engineering Workbook project to add a couple calculators
about FM sidebands (available soon). The good news is that AI provided excellent
VBA code to generate a set of
Bessel function plots. The bad news is when I asked for a
table
showing at which modulation indices sidebands 0 (carrier) through 5 vanish,
none of the agents got it right. Some were really bad. The AI agents typically
explain their reason and method correctly, then go on to produces bad results.
Even after pointing out errors, subsequent results are still wrong. I do a
lot of AI work and see this often, even with subscribing to professional
versions. I ultimately generated the table myself. There is going to be a
lot of inaccurate information out there based on unverified AI queries, so
beware.
