[RFI] RFI hunting on 160: TH-F6a?

[qrv at kd4e.com]

Gee, I grabbed some AA-cells, stuffed them into my F6a, and went
outside earlier - when I saw the original post - then forgot to
post the results!

On a fairly weak AM-BC station, out here in the countryside, I
observed significant directionality e.g. the signal was above
the noise level when I faced north or south and dipped below
the noise level when facing east or west.

It was starting to rain so I didn't attempt further tests.
