[ICOM] Icom 7200 noise blanker

[Paul Manuel]

I'm convinced the best noise reduction step is to move the antenna as far as possible away from the noise. 

I am sitting here with my ladderline feeder located 8 inches from a satellite receiver and 2 feet from a DVD player. I have 6 satellite receivers plugged in right now in the house and also 6 flat screen TVs. My noise level is S-0.

And I cause absolutely no TVI when running a kilowatt on any band.

But my antenna is 300 feet from the house.
