Hello Graham,

> The AM band has been virtually abandoned.

Sad. Maybe it can be revived with some local stations.

FM is bland here as well. IMHO that is because of conglomeration, large
companies owning a whole slew of stations and "adjusting" the music to
mainstream, the same songs over and over. But the local ones is where
you can occasionally find the real blue grass or old style country. AM
is a bit better, lots of ethnic broadcasts but don't count on
understanding the languages.

AM talk radio is popular here, mostly conservative. Some of it has
pretty good quality content so I listen to that once in a while.
Surprisingly most of the contractors seem to listen to it as well when
on a remote job. Also, the driving distances are huge out here. When you
are going clear across a place like Nevada AM is the only thing that
really works in many areas. Actually, when I drove in north eastern
Scotland in the 80's it was similar. Not many FM stations but this was
in an old Ford Cortina with a weak radio.

Regards, Joerg

The radio is used indoors, not in the car.

Yes, I want it to be directional so I can null out
strong stations adjacient to weak ones I want to hear.

try a tap on the coil to create a lower z output to feed to the
radio...

or a small C coupling to the radio from the top of the coil.

A "real" whip anteanna on a car looks like a capacitor at AM
frequencies.

You forgot Hugh Hewitt.

The first 6 are nationally syndicated. I don't think Al or Bill are so
you must be in the LA area, Right ? (I fixed your spelling)

While Bill Handle (Handle on the Law) is on KFYI, I would hardly class
him as right wing... just seems to be really savvy about law.

Actually Handle is the only one on the list that I listen to.

Mornings, I listen to Barry Young (here in Phoenix), then I switch to
Air America just for groans and to keep the "canal" cleaned out ;-)
