Baofeng bother

I like my cute little Baofeng UV-3R+ though I find myself using its slightly bigger brother the UV-5R more often. Unfortunately the UV-3R+ has begun acting up with a fault that is difficult to fathom.

Quite often the UV-3R refuses to switch on. At first I thought that I had accidentally left the radio on and had depleted the battery, because I often do things like that. But the radio comes back to life if you remove and replace the battery or if you drop it into the charger for a few seconds. When I did this today the screen immediately showed a battery voltage of 4.0V which was expected given that it had been charged only a day earlier.

So the radio is failing to turn on even though there is plenty of juice in the battery. Like most HTs it has a "live" power switch and should turn on at the press of a button. The UV-5R on the other hand has a good old-fashioned rotary on/off volume control. Which, I now recall, was the thing that failed on my old Jingtong radio. Ho hum.
