Had a similar problem once. Got a friend to listen in the shack while I
walked around the neighborhood with a sledgehammer. Every time I came

I had a similar problem on 80 meters at my QTH. The power company
couldn't find it. I finally did. I drove the entire area mobile with my
706, trying different bands. Having 2 meter and 70 cm fox hunt antennas,
equipment and attenuators helped me a lot too.

Can you hear it on the AM broadcast band?
If so use the ferrite rod antenna to get directions of it and have

Hi Dave,

Not that uncommon this time of the year! Especially on 160-meters and
