What about just adjusting the frequency of the rcvr higher & higher?  

In addition to being farther away from antenna's resonance, the higher
you go in freq, the closer you need to be to the noise source to pick it

I wented to let everyone know that I've succeeded in mating the Moxon 
rectangle antenna from the March 2001 RFI receiver project to my Icom 
IC-Q7A handitalky.  I cobbled up the antenna out of aluminum rod,
it to a board with screw eyes, and threaded the ends of the rod for nuts
attach the feedline.  The resulting antenna resonated at 137 MHz first
and has a broad front lobe, fair attentuation off the sides, and a very 
narrow cardioid-style notch off the back, all just as advertised.

The only small downside is that the thing is almost too sensitive.
got any suggestions for a simple non-calibrated attenuator that I could
between the antenna and the radio to make it work a bit better close in
the noise source?
