TOM'S GOT GOOD ADVICE.
ALSO IT CAN BE DONE BY USING A "SHOTGUN MICROPHONE" OR A SHARP
INTO A SMALL HAND HELD PARABOLIC DISH TO A PORTABLE AUDIO AMP TO A
HEADPHONE OUTPUT TO HEADS.
WHAT YOU HEAR CAN BE PIN POINTED EXACTLY BY LINING UP THE SHOTGUN OR
SIGHTING THRU THE DISH.
KILL'EM WITH HIGH PHYSICS! GIVE'M SOMETHING THEY CAN UNDERSTAND.
REMEMBER, PAPER YOUR FILE FIRST.
AND REMEMBER" IF YOU ASK THE FCC A QUESTION, YOU'D BETTER BE PREPARDED
