I bought this version of this particular radio because btech upgrades a typical baofeng for better recieve and better selectivity. Unfortunatly...something was wrong internally with the connections on the antenna and would not recieve at all unless the antenna was resting a certian way while being held. I was able to transmit but not receive. I was testing this unit for 2 meter simplex contacts at 1800 ft elevation. And while the radio was getting out just great. I only knew it was working because i had my mobile unit tuned to the same frequency while i was testing the unit. Now on a positive note. On 5 watts at that elevation i did transmit over 35 miles confirmed with 3 amatuer operators. But when the radio would not receive even with the squelch completely open i knew that it was a defective radio. I do believe that you get what you pay for. I cant say i was completely dissatisfied because i was making contacts over 35 miles out on 5 watts. But i wont risk buying another unit that could be defective again. Not a bad radio at all. But buy at your own risk. Just keep in mind that amazon has a great return policy so the only real risk would be wasting time for something that may or may not work. I will say....if it works when ypu get it....you wont be dissapointed with performance. 3 stars because of overall experience.
