Use this handy tool to pinpoint radio frequency interference problems and to know for certain that no one else is transmitting on your frequency. Wide band scanner shows signal strength on all channels in the 72 or 75 mhz bands. Large, easy to read display shows you not only if someone is currently on your channel, but if ambient RF noise or poorly-tuned transmitters are generating interference on your channel.
Audible interference monitor with programmable channel range - alerts you when adjacent channels are in use. Great for older single conversion receivers that are vulnerable to 3IM interference.
Selectable frequency range, channel, resolution, signal level threshold (squelch), and attenuation
Auto power-off to save battery life
