There are older UV-5R Baofengs that are in demand because they didn't have the software restriction that newer ones have. It's not that they're hacked, it's that they were not locked from the factory
Regardless, the Quansheng UV-K5 is largely supplanting the Baofeng as the go-to entry level HT, the 3rd party firmware for that radio is pretty impressive.
Are modern varieties truly locked or just “locked ;)” ?
