Frequency Counter/Tone Decoder

The CD200 is an Analog/Digital (DMR Radio only) Frequency Counter and Sub-audible CTCSS/DCS Tone Decoder. The CD200 combines a frequency counter and tone decoder in one handheld package. Intended for use by the two-way radio technician for quickly checking portables for frequency and tone, the CD200 is so easy to operate that even non-technical staff will find it easy to use.

Whether you sell or rent radios, the CD200 will prove to be an affordable and indispensable tool in your shop. Save time and money by combining a sales call into a service call.  Go from job site to job site and quickly have your customers up and communicating in a snap.

The importance of using a good antenna for your products should not be underestimated. Our wide band antennas like the DB32 and BB85 are useful for picking up a wide variety of signals. However, the narrow band antennas will usually do a better job in their respective frequency range than will a wide band antenna.


It is a good idea to experiment with different antennas to achieve different results.  We offer several different antennas and also antenna packages that offer savings over buying them separately. 

*NOTE:  ALL Antennas offered on this page have a BNC Connector
