The 118-136 MHz aircraft band uses AM. Any radio that receives that
band will have an AM detector that can be used for noise location. AM
is used in part so that multiple signals can be heard at the same time,
so as not to miss a weak emergency call.
Our local power company guy uses a TV set with an RV TV antenna, and
watches the noise in the picture, which is also AM. GL de Dave, W6QHS

ARRL UHF QSO PARTY 1993
Call: N7STU Location: San Jose, Ca GRID CM97
Mode: SSB Category: Single Operator, 70cm only.
BAND QSO QSO PTS GRIDS TOTAL
432 12 36 5 = 180
Notes:
Both operating and propagation conditions poor. I found out early on
that
my oscar array has a very narrow VSWR bandwith so my rig started SWR
shutdown
at 434 Mhz. By the time I hit 432.1 I had barely enough output to drive
the
brick to 10 watts, and had trouble keying the T/R relay. Looks like time
to
re-design the antenna system!
Strong radar signals most of the night and morning.
73, Robert N7STU/YB2ARO
