[MilCom] T-Birds Scanner Tricks, VHF AM High 140's

[Tom M.]

Group,

The T-birds will be in my town soon so I'm preparing my airshow gang to be able
to listen to their comms on VHF AM in the 140's region.

I myself use a milcom scanner, but here are some tricks to hear the T-birds
without a milcom scanner.

#1  I also have a Uniden Sportcat which does not do AM in the 140's however
there is an oldschool trick you can pull, and that is to subtract 21.6 Mhz
(twice the IF freq) from the desired freq and listen to the image. For example
if the target freq is 141.85 Mhz AM, punch in 120.25 Mhz and you'll receive
just fine in AM.

#2  I converted a cheap Lennox Sound or something like that AM/FM/Cassette
walkman (I think they cost about $9) to receive up to 145 Mhz (FM or AM doesn't
matter).  This is done by finding the osc coil for the FM radio section, and
stretching it out until the regular FM stations move down to the left end of
the dial until they disappear below what used to be 88 Mhz.  The radio will now
tune the aircraft band just fine.  I can receive the ATIS from my airport on
134.05 from about three miles away, and amateur packet radio at 145.01.  The
thing is actually pretty sensitive considering, and the front end is as wide as
a barn door so tuning is easy.

Enjoy
