I wouldn't be in a big hurry to do that -- most noise sources that we 
hear on 160M will also be heard both above and below 160M -- they're 
either clocks for microprocessors, switching power supplies, or impulse 
noise from the power system.

The TH-F6A does, indeed, have the directivity you would expect from a 
loopstick, but its sensitivity is quite poor. I use it when I get very 
close to sources in that frequency range -- it's great for identifying 
WHICH box or cables are radiating the trash. The Tecsun has FAR better
