I hope that everyone here is fully aware that any portable radio which has a 
built-in loop-stick type of antenna exhibits MARKED directional capabilities.

The common loop-stick antenna is, essentially, a minature loaded loop 
antenna with very deep nulls broadside to the loop.

If you must, you can open up the radio in order to determine the orientation 
of that loop-stick within the radio, then as David pointed out, all you have to 
do is to rotate the entire radio to determine a direction to a noise-source.
