Why does my Wouxun lose its programming?

From amateurradio.com

I own a Wouxun KG-UV2D from Import Communications and a KG-UV3D from HRO. They are both great radios and I honestly can’t complain too much about their small annoyances. They are extremely affordable and have proved durable and reliable. They represent a great value and I continue to recommend them.

About a year ago, however, my KG-UV2D developed an annoying habit. Out of the blue, it would lose all of its programming and revert to some kind of factory default. The condition is easy to detect as it starts talking Mandarin on power up. Really handy if you’re in the middle of something important.

At first I attributed the problem to the fact that the radio may have been dropped one too many times, and maybe I’d bent the battery contacts causing the radio to somehow reset itself. I bent the contacts out a little and things seemed to be OK for awhile. After it started happening again, I invested in a second Wouxun, the KG-UV3D, and relegated the KG-UV2D to backup status. It still worked fine, but it I had become concerned about its reliability.

Fast forward a year…. Now my KG-UV3D is exhibiting the same annoying problem. Is it due to user error? Abuse and neglect? Maybe, to some degree. But I find it strange that the same problem has now occured in both radios.

There is very little information online about this problem, but there has been some discussion about it occurring. Some people report that it happens when you let the battery run dead. Others report that it can occur when swapping batteries. Neither of these scenarios describe my situation. My radios were fully charged and I only use the batteries supplied with each radio.

One common factor between both radios is that I use the excellent KC8UNJ KG-UV Commander programming software. I have had great luck with this and recommend it for its ease of use and intuitive memory channel management. Could there be something about the software, how I’m using it (number of memories or settings), or how it programs the radios that is causing the radio not to retain programming in some cases? This really doesn’t make sense as I know MANY people who have used this software without any problem.

Have you experienced similar problems with your Wouxun HT or heard of it happening? If so, have you had any luck tracking down the issue?

Thanks in advance!

All I have discovered so far is that the voice announce function has gone away for some odd reason. With these radios starting to age now, we could see some longevity issues crop up… definitely a thread for the Wouxun Yahoo group.
