Baofeng UV-B6 frequency issues above 499Mhz

The Baofeng UV-B6 (and B5 too, I’m assuming) are factory programmed to operate UHF up to 480Mhz. You can easily unlock this to 520Mhz through either the Baofeng software or CHIRP.

However, the radio exhibits some really strange display issues when you tune above 499Mhz. Take a look at the two videos below for a demonstration.

It’s also worth noting that the UV-B6 antenna that mine came with was only indicated for use up to 480Mhz. Yours may be the same.
