Frequency
Counters
are a RF detectives best friend..
Useful for finding those rarely used frequencies,
determing what frequency that radio
for sale at the flea-market,
checking for bugs! and so on..
Theres
only a handful of companies that make
frequency counters portable..
Almost all counters only count, and do
not produce audio of the signal.
Different dealers enjoy massive price
markups on these since they are so rare.
Theres only a couple companies that even
make them!

| Basic Counters |
These types of counters just display
the frequency of any high
powered analog transmission thats within
a couple hundred
yards or less. Anything less than 1 watt
and you usually
need to be on top of it. Some even decode
subaudiable info.
(see next section labled Ctcss/Dcs/Dtmf ) |

This type of counter can
automatically tune a connected radio
receiver or scanner to the frequency it
detects instantly! |

Digital counters can pick up pulsed
data and other types of short
duration digital transmissions such as
TDMA, GSM, etc. |
