A good portable 'shack-in-a-box.
I spent a lot of time looking at online reviews of this radio before making a purchase decision. Overall, I am pleased with the radio; it is well built and easy to operate and is ideal for the portable operations that I have in mind. Since receiving it I have updated the firmware,which was incredibly simple, I have programmed repeater channels using software and direct input and tested HF and VHF operation. A manual is included but it is for the V1 radio, an updated manual can be found on the included USB key or downloaded from the manufacturer\'s website. The PMR - 171 is not my first Chinese radio and in terms of quality and function, I think that it compares well with other products on the market.
