Re: radio in '22
For many years (I don't know about now), the WLAN calls
were on an AM 1390 in Lancaster PA. This was long after
1922, however. In the networking business (local-area
networks, such as IEEE 802.11b and .11a), the acronym
WLAN has stood for Wireless Local-Area Network for at
least the last five years or so.
As Donna Halper will tell you, 1922 was a banner year
for radio station startups. I'm guessing that, in the
United States, several hundred stations went on the air
for the first time in 1922. Only a handful have survived
and of those, an even smaller number retain their
original calls. One that I know of is WHAZ in Troy NY.
The other pioneer station in same market as WHAZ, WGY,
Schenectady, first went on the air in 1921, I believe.
None of the stations that have survived operates on the
same frequency as it did in 1922. The "broadcast band"
in those days consisted initially of just
one "wavelength," 360 meters, which works out to about
833 kHz, and crystal oscillators--if they existed at all-
-were so unstable that the stations frequencies drifted
around by many kilocycles/sec. (The unit of frequency
wasn't renamed the Hertz until the 1960s.)
