40-Channel Mobile CB radio

Model 77-250CXL Professional CB Radio

     The Midland 77-250cxl Power Max is a technological breakthrough. Midland named it for the way it works: loud and clear. Power Max is a professional class radio with the highest level of modulation found in any CB. The new ESP®2 system (patent pending) reduces noise up to 95% and makes you sound better, even when talking to CB’s without ESP®2. **

     Midland also did more for reception than you're likely to find
anywhere else: They gave it a highly sensitive amplifier to improve
signal-to-noise ratio, and a special filter to virtually eliminate
adjacent channel interference. Included is a new analog meter system, a built-in SWR system to monitor antenna performance, plus all the controls you asked for. **

Check out Midland's Power Max.  It'll give you something to call home about.**
