Hello everyone I am looking for detailed plans for an AM loop. I will
be using it only for one frequency 1370AM so I dont want any tuners just a
simple AM Loop antenna for my AM radio. I will have to solder a 1/8 plug
to
a 6-8 ft feedline to connect to my radio. It is a Kaito portable model
1103. I want to built this AM Loop cause I listen to talk radio alot and
the static and other distant stations sometimes make it hard. I have done
alot of looking around on google searches but have found no real detailed
plans I am not sure if I should go with edge wound or Spiral wound. Any
info you guys can give especially a detailed plan would be greatly
appreciated. or maybe there is a website I may not have seen you would
like
to suggest. I am sure I have seen most of them atleast the most popular
ones. Anyways thanks in advance for any input Bill

Bill,

Refer to the posters who recommended you search the web. Find a tested
design. There are so-o-o-o many variables.

A few notes from my experience; You can couple to an existing radio four
ways (assuming you don't have a ready-made External Antenna jack):

a) Solder a wire onto the tuning capacitor of the existing radio. This will
detune it, so you'll have to adjust the trimmer. This worked wonderfully
well for a cheap battery portable radio that I used on a Navy ship. It has
decent AM sensitivity without anything connected to the wire, but inside the
ship I needed the connection to use a ship's antenna which was available to
me.

b) Wind a few turns of wire around the AM loopstick, connect one end to a
ground and the other end to your external AM loop.

c) Same as above but wind the turns around the whole radio. You probably
get poorer coupling, but you don't need to open the radio.

d) Put the loop near the radio. (See following anecdote.)

Some years ago, having the same need you describe, I built an AM loop with
a random coil and a junk AM radio tuning cap to resonate it. I just dug it
out. The coil consists of 18 turns of hookup wire around the lid of a paper
case, the box that hold ten reams of printer paper. It only tunes the
bottom third of the BC band, so it's probably got too much inductance. I
can couple to a radio merely by putting it next to the radio; the
improvement is most noticeable on weaker stations and the effectiveness
varies wildly with the orientation of the radio and the loop. If I added an
external antenna wire and a ground, things would change.
