I would like to suggest that we purchase the UV-B5 instead of the UV-5R. The B5 has a much better front end. Review Baofeng UV-B5 / Baofeng UV-B6 | Ham Radio Blog PD0AC
Something changed. From the moment I switched on the Baofeng UV-B5 it was clear that engineers in China heard our cries and did something about these crappy front ends. First of all I never lost the signal of our regional 70cm repeater while walking through my house, a trick not even the Wouxun or Quansheng can pull off. Only my Yaesu VX-177 and Icom IC-U82, both expensive mono band HTs, are capable of doing that. Secondly, I never lost signal outside either. That’s not something I can take for granted here. My QTH is known as ‘Intermod Alley’ and for good reasons. Most receivers are overloaded immediately here, making it impossible to listen into any 70cm signal below S9+20.
