Quansheng UV-K6 Upgrade UV-K5 (99) Intercom 5W Flugfunkband Radio Typ C Aufladung UHF VHF DTMF FM Scrambler NOAA Kabellose Frequenz

A simple device, yet very sophisticated, that is not a toy. I have already received several and they require a license. If you need it, it's better to buy a PMR or GMRS radio if you are in the USA.
It also requires a filter to prevent interference from commercial FM radio if you are near a powerful radio transmitter. A very interesting device that allows you to change its firmware and add new options for the 144/146 MHz and 430/440 MHz bands.

Cheap and high-performance. Even if you're a beginner, it's easy to use. The speaker's sound has a strong treble. I think the speaker is small, but it's clear. The TX and RX frequencies are slightly narrower than indicated, but it's still usable.

Everything is okay, the radio receives the air band, vhf, and uhf correctly. amazing battery! i received the v3 version. i recommend it.

The unit works well.
Programing the channels is not easy but after a lot of trying i think i am getting there.
Receives air band very well and i have used it on 2m ham band with good results

Excellent! It works very well in both transmission and reception. It includes an AM airband and the firmware is highly customizable, allowing a frequency spectrum analyzer to be installed.
