THIS UNIT WORKS WITH THREE SETS OF FREQUENCIES AND DIFFERENT WATTAGES, I NEVER OWN ONE OF THESE AND I'M UNFAMILIAR WITH A DIFFERENT WATTAGE OUTPUT. I USE AN AVERAGE WATT METER, IT HAS CLEAR TRANSMIT AUDIO AND WILL COME WITH THE DRAKE 1525 HM-MIC. ALL LIGHTS ARE WORKING INCLUDING THE METER, THE SPEAKER DOESN'T WORK, SO I USED THE REAR SPEAKER JACK AND IT SOUNDS GOOD. REMEMBER THIS ONE WORKS ON THREE DIFFERENT BANDS 144, 220 AND 440 MHZ SO MAKE SURE YOU HAVE THE ANTENNA HOOK UP TO THE PROPER BAND REAL IMPORTANT 144 LOW IS 2 WATTS HIGH AS 45 AT 220 LOW IS 1.7 HIGH IS 18 AT 440.
5 IS LOW AND 17 IS HIGH ALSO COMES WITH THE POWER SUPPLY AND THE POWER SUPPLY WORKS GREAT I RAN IT FOR 4 HOURS WITH NO PROBLEMS.
