> Subject: [TowerTalk] near field pattern on 6M?
> I have an interference problem on 6M. there is a noise source that seems to
> be due north from my beam. The noise is about 800 Hz wide, and is, at
> different times, anywhere from 50.125 to 50.131 MHz. (Right- right on the
> calling frequency) Strength is about s9.
> The problem is that my shack is due north of the beam, and I am wondering
> if the source could be in the house. The tower is 60 ft north of the shack,
> and the beam is at about 53 ft, just above an ATB34 tri-bander. THe 6M beam
> is an MFJ 3el Yagi. THe booms are aligned.
> The geometry puts the receiver (and my computer) directly in line, but at a
> very depressed angle, to the beam. THe question is- is there a chance that
> the pattern is directive enough to "see" anything from my equipmqnt. or is
> it more probable that the souce is at a greater distance, and the line-up
> is coincidental?
> opinions solicited. I dont have a portable 6M Rx to walk around with. I may
> need to get one.
