what is the best filter to buy for my part 15 am.station
 

i need a filter for my part 15 am radio just to be on the safe side
cause the army choppers fly around here frequently

Probably not a problem. There communications are normally FM. The only AM is
on the aeronautic band around 120 Mhz and Army common 243 Mhz. :)

How much power are you running, and on which frequency? Necessary info to
help you with a filter.

Lemme see.... At 1700 KHz I would say that the optimum filter would
be a piece of copper strap about 1/4" wide and 1/2" long placed right
across the output of the transmitter.

Stop back sometime and let us know how this works out.

Scarcely seems like a "Part 15" AM station under those conditions?

If at first you don't succeed, skydiving is not for you.

May I suggest that you direct your enquiry to the nearest FCC office. I'm
sure they will be very keen to help you!

Meaning not. Which is the important part.

ok guys the station is on the air i set the freq on 1700. and a very
long wire ant . about 20 ft high over 100ft of wire damm took most of
the day to set the post in i could only put in a big loop had my other
pirate pal to help me take care out there in radio land from alabama
radio

100 foot of wire on 1700Khz is not a correct length antenna. It is unlikely
that your "part 15" device is matched to the new antenna, and may be worse
than the legal antenna that came with it.

You did not mention what you were using as RF ground.

Genetic self-thinning mechanism.

Wait till he finds out about 120 wires each 250 feet long. ;-)

PR:

Explore 1/2 wave antennas, you can load then with an inductance(s) to
achieve the 1/2 wave electrical length, and they will work against a
minimal counterpoise (chain fence, spare travel trailer you have parked
around, metal shed, etc, etc....)

Long, long ago I ran a pirate am broadcast station using an old 50 ft. tv
mast with loading coils and a heavily modified gamma match which used
loading coils in its construction, was able to be heard for over 100 miles
in the most favorable direction running 100+ watts though an old military
transmitter... back then there were many pirate stations around...

Hmmm! You come in asking for advise, and when given same you get defensive
and profane... Next time ask your question in

A 187 foot vertical will suit your needs much better.

Add 120 300 foot long radials around the base of the antenna in a fanned
out configuration and we will know you are really serious!
