Description

These were sold by RETEVIS Official Store on AliExpress recently at very attractive prices. Bought a few out of curiosity.

None of the UV-5R settings in Chirp permit communicating with this radio. I get "Radio refused to send second block 0x1ec0" alert in those that sort of do.

This variation of UV-5R has no manufacturer markings or stickers on it. Just some OEM (?) numbers underneath the battery.
Display fonts are different.
It has NOAA menu (41).
It permits to input almost any frequency from the keypad. Tx outside of 136-174/350(!)-520 MHz seems to be disabled. No extensive tests yet.
Powering up with '3', '6' or '8' pressed doesn't show firmware version at all.

Debug log attached.
