The AM stations do not always follow the rules.
The two 50 kW AM BC stations near me
sometimes run all night at full power. Neither
is a clear channel station. I checked and they
should drop their power at night. Who is to
check on them? The FCC does not do it.
Using an antenna tuner will narrow the bandwith
of the antenna. I now mostly use my vertical which
has no problem. When I use my long wire I need to
use the attenuator or antenna tuner. My Pegasus has
lots of gain even with the attenuator 160 to 40.
The noise level on those bands it high enough so the
attenuator does not hurt weak signals. I would like the
high pass filter also. How do I get one?
