Correction to the product: the device may also 6.25 and 12.5 KHz - grid, not only 25 KHz.
To radio:
Sender: The (my) machine sends about 3-4W at the antenna output.
Modulation: As requested by a handheld radio very bright and even in ambient noise by the radio partners clearly audible.
Antenna: The supplied antenna seems to work well - I have not measured it. In any case, I can work through a repeater in 80km distance, at least until halfway clear line of sight.
Receiver: is good and sensitive as with all these devices. Even the speakers and the volume control work as they should.
General:
Programming via PC is a bit tricky, but should get. Here in the comments, there are hints. Without programming cable (separately) to acquire is not programmable. It fit all the programming cable, which also function for Kenwood (the one with the 2 parallel connectors halt). Should get from 10.
Battery performance:
I have the power for days on my way to work and back with and use it very often. Even when I'm with the dog outside. Rare that I do not come with a battery charge by a workweek.
Charger:
Let's say, under the circumstances. It works, the charger is very light and looks rather cheap. But quite functional.
The manual is China typical sparse.
Conclusion:
A fair equipment at a low price. The performance is good. As a second or third device, etc. to recommend local telephone warmly.
