i was listening to these two frequencies but could not figure out who or
what they were for, so i was hoping you guys might be able to identify them
for me.

4540 khz at 00:12 utc on jan/11/04 it sounded like wwv with the time carrier
beeps but there was no voice saying at the tone it will be such and such a
time.

now the second frequency was 5550 mhz at 00:20 utc on jan/11/04 now it
sounded like a control tower for an airport. i don't think it was here in
toronto (pearson). they talked about "heavies" and allot of co-ordinates,
numbers and acronym's.
they also mentioned a back-up frequency of 3455 mhz.

that's about all the info i can tell about these two. i'am hoping someone
can tell me about them.

thanks
chuck

Thats aviation. If you listen to the pilots when they call in, you can
usually tell which radio center it is. IE: New York Radio, San Juan,
Houston Radio,etc..
There are many in quite a few cities. A "heavy" usually means a
heavily loaded plane, full of people, full of fuel. IE: a fat loaded
747 might ID as United 247 "heavy" as an example. The co-ordinates are
waypoints or location fixes. You will hear many "sel-cal" checks. This
is a system used to ring a chime in the cockpit. That way they don't
have to listen to all the chatter in order to monitor for any calls to
them. They use a 4 letter designator, "IE: BFHE as an example" and
you hear a two tone transmission when they send it. IE:
beeeeeeeeeeep-booooooooooooop...They do checks to make sure it
actually goes off using the intended sel-cal. Air nav website sells a
sel-cal decoder and should have a demo. I've tried it. It works. I'm
listening to 5550 now... Just heard one transmission...Didn't catch
the ID, but the sound of the female controller sorta sounded like New
York radio....Not sure though...They also gave out 6.577 as a
freq...BTW, these HF radio "centers" differ from the VHF side. The VHF
"centers" are run by the gov, and are free. The "radios" you hear on
HF are privately owned co's. They charge the airlines for this
service. We have one hear in Houston. It's called Houston Universal
Radio. They have a website. Houston radio can be found on 6377,
10075,13330,17940, and I'm sure others...Many US cities have them. New
York, Miami, San fransico, San Juan, , etc, etc..Also, worldwide. MK

Good info. One correction though. The term "heavy" has nothing to do with
load. It's size. Full size commercial jets such as 747, 757, 737, ect. are
"heavies".

Thank you for the post, you answered my questions. Unfortunately I had
searched in vain for cell call, and never found the relation to aircraft.
With the correct spelling of Selcal, I am now enlightened.

I had spoken to a coworker that has aircraft airframe and avionics repair
experience about the HF radio application, all he was aware of was the
VHF application of the radios.

He has stories of coffee spilled into the consoles ruining radios, which
reminded me of a movie that I saw addressing a similar situation.

"Fate is the Hunter", from 1964, http://www.imdb.com/title/tt0058091/
starring Glenn Ford and Suzanne Pleshette.

A plane wrecks with the Stewardess as the only survivor. The plane lost
an engine, and was attempting to return to the airport when they got a
warning light indicating that their other engine also failed. They
attempted to crash land on a beach, but weren't successful. (1 survivor?)
Glenn Ford wanted to recreate the accident to vindicate his buddy who was
piloting the plane. The recreation involved the stewardess doing exactly
as was done on the flight. This included the coffee being placed on the
console. When Glenn Ford ordered one engine shut off the plane lurched,
and the coffee spilled again. Glenn was forlorn since the loss of the
engine offered no explanation as to the crash of the plane. As they were
returning to the airport, the annunciator indicated the loss of the
remaining engine. As the copilot reached to shut off their remaining
engine, Glenn realized that the annunciator was false and kept the engine
on.

This begs the question as to why pilots would keep their coffee on the
console? My coworker said that pilots will put their coffee on anything
level even though there are places to put the cup. He said that he has
pulled radios out that were literally dripping with coffee. Bear in mind
that many of the planes that he worked on were commuter flights, so I'm
not sure as to the model or size of the planes concerned.

Regards.
