If you intend to use this radio to transmit, you may be in for a surprise. I was, three times. Of three Cobra 19 Ultra III CB Radio's purchased from Walmart, none properly transmitted modulated audio under normal conditions (voices transmitted are very, very weak when received by another radio). My operating conditions included a quality amateur radio antenna tuned to resonate at the operating frequency of 27.185 Mhz (Ch 19). On two of the radios, I followed the functional test from within the vehicle with a bench test which included a power meter and dummy load. The radios would produce 3-3.5 watt carrier with minimal meter deflection under normal operating conditions. Normal talking with the mic held close to the face resulted in very minimal deflection above the power produced by the carrier. Yelling loudly produced a slight deflection of the meter to near 4 watts. Although audio was being transmitted, under these conditions (yelling), the transmitted audio was distorted and garbled (during the functional test). The only recommendation I would give for this radio is that someone in the Quality Control department of either Cobra or Walmart give this product an evaluation as the three that I have worked with have been virtually useless with respect to their intended purpose.
