There's another way -- battery-operated RX that can tune operating 
frequencies. Several good ones listed in my applications note on chasing 
and killing noise.  k9yc.com/publish. htm  My favorite is Kenwood TH-F6A 
talkie that has wideband RX from below AM BC to about 550 MHz. Excellent 
probe for noise. Several others listed, including one that costs under 
$50 and tunes to 30 MHz
