Concerning _frequency counter_, Glenn Fetty said to All in SCANRADIO:

The problem with frequecy counters is that they give you the frequency of the 
strongest signal.  If that's not the one you're interested in, you're SOL.
Take fast food joints, for instance.  I listen in to Long John Silvers when I 
eat there.  They use different frequencies for the order box and the headset. 
Headset-to-order box is around 154 Mhz.  Box-to-headset is around 33 MHz. 
Problem is, the box-to-headset is on constantly and is very strong.  The 
headset transmission is infrequent and and weaker.  A frequency counter would 
lock on to the box-to-headset frequency and never give you an indication that 
the other signal existed.
My main method of finding new frequencies is a Rip-off Shack Pro-2042 
scanner. Sometimes I give it a frequency range and let it autoscan out in the 
car while I'm in the restaurant or whatever.  Later, I'll take the "found" 
frequencies and enter them into my handheld scanner and see if I can't figure 
them out.
Of course, the 2042 scanner is about $400 more expensive than the freq 
counter you're talking about.  :-)
Which reminds me...  The Communications guys at work have a new "secret" 
frequency on their radios that they think I can't listen to.  I simply must 
remember to set up the autoscan the next time I'm at work.
