[MilCom] 254.2 Mystery

[Don Munson]

My first instinct is that you have copied a great case of ducting.  But if
you have been hearing this for awhile that would not explain it.  Can you
correlate the comms to a weather pattern?  I know they typically move faster
than "days" but if you have a string of them back to back ........ Really
reaching.  

Can't answer the sat question but that is another good explanation.
Although I'd have to think someone who uses that uplink/downlink pair would
have said something a LOT sooner :)

Well get ready for this one...Last night 254.2 started becoming active again
at around 9pm. This time there was a male approach controller, vectoring
aircraft to runway 34r and telling them to contact tower 118.4, just like
the night before. The signals were up just a bit, enough for me to make out
flight numbers and such. After listening for about 15 minutes with nothing
said by this approach controller to id himself I heard United Flight 1131
being vectored for a approach to runway 34R. A quick search of the internet
revealed that United flight 1131 was inbound Calgary, Alberta Canada from
Chicago. WOW, How am I hearing this? I looked up the airport in Calgary and
sure enough, they the 34R runway, and the Tower freq is 118.4, just exaclty
what the controller is refering too. After looking up several flight numbers
that the controller was talking too I am 100% for sure that this is the
approach controller at Calgary airport. The question is HOW am I hearing
this??? I have se  en 254
.2 listed as a SATCOM freq in some places.  Could Calgary have a UHF
approach frequency on the input of that transponder if it exist? Thats all I
can come up with, as I cannot find Any listing of UHF atc freqs for Calgary
Alberta. I also have another hour or so of audio I recorded last night with
better signal strength than before if anyone wants to listen to it. Anyone
else hear this or shed some light on the subject???
