Sell AS IT, used RAMSEY COM3 COMMUNICATION SERVICE MONITOR, working condition, just the unit & a owner manual on pdf. file, nothing else. it has some rust on the cover, and thats about it. NO WARRANTY....SELL AS IT...!
The COM3 is used around the world for testing two-way radios, amateur radios and repeater stations, hobby equipment, pagers, and more! It?s easier to set up and use than competitive units. It is small and light, weighing under 18 pounds with the battery pack installed (fully portable!). And it?s priced for the serious hobbyist, amateur radio operator, or amateur radio repeater owner! Imagine having a full function service monitor, just like the pro?s!
* Covers All Pager and 2-Way Frequencies
* Built-in Frequency Counter
* AM & FM Internal/External Modulation
* Direct Numeric Frequency Entry
Performs the Tests You Do Most
Measure deviation and frequency error with an easy to read bargraph display.
Don?t know the frequency? No problem, a built-in frequency counter an determine and display the exact operating frequency and even the CTS tone in seconds! No guessing! Check receivers with the full range RF signal generator that also includes built-in CTS and tone generators!
Direct Access Function Selections
No fumbling with complex, shifted-key functions or embedded layers of ?soft keys.? The direct entry keys are logically grouped, on a sealed membrane front panel, and directly accessed with a single keystroke.
Whether you?re working on a 2-Meter, 220 MHz, 440 MHz, 900 MHz, or anywhere in between, the COM3 has you covered...anywhere from 100 KHz to 999.999 MHz, AM or FM.
