Richard -- this all started when an inquiry was made by a gentleman whose
Dad worked for RCA and had license W10XEG in the 1930's
It appears he worked for RCA conducting early TV experiments and the
following quote heralds the early TV experiments on top of the Empire stae
building
Quote from URL:
http://www.earlytelevision.org/pendletonpaper.html
"The first all-electronic American systems in 1932 used only 120 scanning
lines at 24 frames per second. This produced a blurry image with visible,
thick scanning lines and a noticeable amount of flicker. RCA transmitted
from both their Camden, New Jersey laboratories as well as from atop the
Empire State Building to a handful of experimental television receivers
located within a few miles of both areas.14 "
Also note that some early TV experimental stations operated around 2 Mcs --

Quote:
"Mar. 30, 1929. Radio Service Bulletin lists these new stations: W9XAO
Chicago IL (Nelson Brothers Bond and Mortgage Co.) 2.0-2.1 MHz, 500 watts;
W2XCR Jersey City NJ (Jenkins Television Corporation) 2.1-2.2 MHz, 5000
watts; W2XCL Brooklyn NY (Pilot Electric Manufacturing Co.) 2.0-2.1,
2.75-2.85 MHz, 250 watts; W2XCO New York (RCA) 2.1-2.2 MHz, 5000 watts; W2XR
New York (John V. L. Hogan), 500 watts (visual broadcasting and
experimental); W2XCW Schenectady (General Electric) 2.1-2.2 MHz 20,000
watts."
So I suspect that the sender meant 2.1 Mcs not 21 Mcs
You are correct about the later TV allotments which can be seen at URL:

The originator of the W10XEG question supplies the following new info:
Actually, the W10 call is most likely a commercial call. There were
several
'repeaters' that were used very early in the establishment of the radio,
and
then commercial television networks - it may be one of those. The X is
for
experimental, no doubt. My Dad was very active with RCA very early on.
The
first experimental TV signals in NYC were on 21 MHz, broadcast from the
Empire State Bldg - my Dad was chief engineer for the transmitter. One
of
the many experimental transmitters he put on the air was W10XEG - I just
have no data about it at all.

Opinions are the cheapest commodities in the world. Author unknown but
"right on"
I had heard that the early "Channel 1" TV stations in NY and
Chicago were in part of the later 6M amateur band; 48-54 MHz
if I remember correctly. That is why there is no TV Channel
1 today. After WWII, the 6 M band was carved out about the
time the VHF TV channels were allocated. Do you have any
hard info about the use of 21 MHz for TV Ch-1?
