Default Need Help Idenifying Interference on Voice of Korea Broadcast

Thanks. That is very helpful. I am new to all of this, and trying to
figure it out.

I think that most of the noise is actually coming from my house, and if
the wire picks it up, it is probably near to where ther eceiver is.

I just ran to wire high, to see if that helps, and tomorrow i am running a
new, longer length that will be even higher. If that is still noisy, then
I am going to look into running coax from the wire (connecting near the
roof), to the receiver. I need to read up on that some more.

Also, I dont have the wire grounded. I have been reading on that also, but
am not yet clear on what, if anything i actually need to do.

For grounding, I bought two eight or ten foot grounding rods from Home Depot
(copper coated steel with one end pointed and the other having the edges
rounded off) and drove them into the gumbo we call dirt around here with a
three-pound sledge (I think.) Got some grounding blocks from the local
parts depot and clamped them onto the rods with clamps also from Home Depot.
Fed the coax into and out of the grounding blocks so that the shield of the
coax made contact with the grounding blocks. Did this where the coax came
off the roof, and where it went into my window, so that the air conditioner
that the coax went past didn't cause any interference, and have a nice quiet
connection.

Good luck. Don't hesitate to ask if you have any questions. Someone will
have the answer.

Dave
