I haven’t experienced this problem myself, but I’ve been reading more and more about it lately, so I wanted to throw up a post here, just in case some of you aren’t aware.
Apparently there is a known defect with ALL Wouxun Model HT Radios, according to Ed from Import Communications, verified by Matt W1MST from AmateurRadio.com and the comments on that post. I also read reports from Brick and from Hans over at Hamgear.
ALL Wouxun dual band radios have an internal defect that the factory refuses to address. They know there is a problem, they know how to fix it, but they will blame the problem on everything in the world except what it really is. Without warning, any of their dual band models can “lose memory”. One day when the radio is turned on, it will revert to speaking Chinese and the display will show channel numbers instead of channel names. Often the programmed channels themselves will be gone. Reprogramming the radio may restore it for a short time but often it’s cured for only one off/on cycle.
I have not had this issue myself, nor have I heard about it from any of the hams that I speak with locally. I know that several of them use a Wouxun radio.
Post here if you have ever had this problem. From these reviews above, it sounds like it is wide-spread, though Hans mentions that statistically, it is still a small percentage.
Also it seems that Ed has the new AnyTone AT3318 radios on sale for $99. Well, those who know me know that I can’t pass-up a new HT. So I’ll be ordering one of these soon and posting my review here.
