When it comes to keeping track of Baofeng / Pofung flaws, the Miklor page is way ahead of me. I only run into newer models by accident, but don’t order them anymore. It’s just too expensive.
The latest UV-5R bug pointed out by John K3NXU involves muted RX audio when the keyboard beep is switched off. Personally I find keyboard beeps very annoying, and always switch it off. No new model for me, that’s for sure…
It’s a bit of a silly bug, created by a sloppy programmer, and never caught by other Baofeng employees responsible for intercepting these things – if such employees actually exist. Let’s face it: the UV-5R is a dirt cheap product, having competent QA personnel on the payroll might not be feasible.
Not the first time
Since its inception the UV-5R had its fair share of bugs, from being off-frequency on receive to muffled TX audio to meaningless squelch levels. Under ideal circumstances bugs wouldn’t be a problem: just update the firmware and you’re fine. Unfortunately this can’t be done: UV-5R firmware can’t be updated afterwards.
If you can’t live with the bug, the only thing you can do is send it back or wait for a new version to come to market. If you bought directly from China, sending back the radio is often more expensive than buying a new one. Basically you’re screwed. Food for thought if you love conspiracy theories: Baofeng does it on purpose!
