Which one of super chief's ships had over 30 HF transmitters,
and all of them 1 KW or higher?


All "big-time radio communications experience" does not happen on HF,
30 transmitters is not a remarkable number of transmitters, and power
levels of a mere 1KW are distinctly small-time. But to satisfy your
criteria, here are a few examples of my assignments with more than 30
transmitters, 1KW or larger.

At NAVRADSTA(T) Barrigada 78 transmitters none smaller than 5KW
(AN/FRT-39). Largest was 200KW (AN/FRT-72).
At USS Annapolis AGMR-1 48 transmitters, none smaller than 1KW
(AN/URT-23). Largest was 40KW (AN/FRT-40).
At NAVRADSTA(T) Driver 55 transmitters none smaller than 10KW
(AN/FRT-39B). Largest was 600KW (AN/FRT-100).
At COMSECONDFLT, uncounted transmitters situated on more than 150 ships,
including 8 aircraft carriers.

How many 200 KW and 600KW transmitters did the super corporal of ADA
operate?

With all kind wishes,

Hans Brakob
Master Chief Radioman, US Navy




Hello, Hans

Most interesting, indeed. Just out of curiosity, do you have an idea of how
much power the Navy uses on the VLF stuff? Just curious. When you start
talking 6 zeros in the power level, three zeroes *does* start to look pretty
small time

Best regards from Rochester, NY

QST had a story many years ago when the VLF station in Maine was first
opened. I remember
a picture of a man standing up inside the coax. Power was in the 2
Megawatt range.

I don't know current QRO, but in the 70's the COMSUBLANT transmitter at
Cutler was 1,700,000W on 15.9KHz and the COMSUBPAC transmitter at Jim
Creek was 2,200,000W on 17.1KHz. The ELF site at Clam Lake is
reportedly engineered for just under 1,000,000,000W at somewhere just
above powerline QRG, 75Hz if I remember correctly. The antenna is just
under 29 miles long.

None. ADA was/is an ARMY callsign. :-)

ADA is presently the Headquarters call of the USARPAC (United
States Army, Pacific) located at Fort Shafter, Hawaii.

I have no idea what USARPAC is running on HF now. Left ADA
in 1956...that's 48 years ago. The facilities of ADA were
transferred to the USAF in 1963 (callsign changed, equipment
the same) but the USAF closed that entire facility down in 1978.

There's an "HF Department" of the 78th Signal Service Battalion
stationed at Camp Zama, Japan, under the 516th Signal Brigade
at Fort Shafter. I don't have any details on what the 78th has
nor of any extensive "inventory." :-)

Back in late 1954 the 40 KW Collins transmitter hadn't yet been
given the military designation of AN/FRT-22. :-) For that matter,
the 24-voice-channel GE microwave terminals (commercial)
weren't given the "official" designation of AN/FRC-25...the
"credential" for such importance consisting of sticking on a label
on each of the six terminal racks' doors, thereby making it
"military." :-) Those just kept on working into the USAF
responsibility shift.

ADA was never the biggest Army station, those facilities
probably never the biggest USAF station after 1963. The ADA
receiver site at Camp Owada was shared with the USAF in the
1950s and was described as the largest receiver site in the
world at the time with pairs of rhombics for each circuit (space
diversity with multicouplers and diversity adapters) and the
whole works running 24/7. TTY Relay at Chuo Kogyo (later at
Building 898, North Camp Drake) handled 220 thousand
messages a month in 1955. Not the biggest since WAR
(Washington Army Radio) TTY Relay handled 1.2 million a
month in that same year. Except for some trials of mods, all
the rest of the TTYs ran at 60 WPM rates.

That was a half century ago. Times have changed. Some
ideas of what the U.S. military does now, or even did back a
half century ago are purely imaginary in the minds of those
that weren't involved in military communications then or later.

Yes, I was a corporal back a half century ago, a PFC before
that, and the equivalent of today's SSGT afterwards, that as
an operating team leader and later as a supervisor of
microwave relay operations and maintenance. All in three
years of that assignment. Thank you for mentioning it. :-)

I could not dare to achieve any heights of greatness nor the
nobility of purpose or excellence of the United States Navy
in a short volunteer military active duty time of 4 years...not
even in the reserves for 4 more...just army stuff, what an ex-
murine called "radio clerk" things. :-)

Thank you for the rendition of "Rancors Away..." :-)
