While checking for radio birdies on my scanner, I noticed that I swas able
to
pick up a few stations without an antenna. (some were voice, some were
data).
I'm assuming this means that I'm close to these stations, signal-level
wise.
Since I can pick these up without an antenna, would this mean that it's
intermod or just the actual frequencies the stations are on? or could it
be
either one?
if it's strong enough...both
When using my scanner to listen to these particular frequencies,(with an
antenna, of course) should I use the attenuator to null them out or not?
yes
I ask because I'm not sure if it's intermod or the actual frequency of
these
stations that I am hearing.
check a listing website
On a slightly separate note, one station I hear that I now know is
intermod
thanks to this group is the 162.55MHZ weather station in the 200 MHZ
range, but
I didn't pick up this stationn at all on either frequency without an
antenna.
My questions for this post concerns stations that I am picking up without
an
antenna. And I live in a "semi-rural area". (official description).
lastly, i question the term you describe as intermod.
it's from poor IF design & filtering you are getting the problem - swamping
it- a mixing product of two (or more) strong stations being 'up' at the same
time.
though, ofcourse, the result is, you hear two or more conversations on one
channel
