I have two of the Wouxun KgUV3d radios and haven't experienced that problem, however the 3d radios come through Powerwerx, and they are sold at Ham Radio Outlet. Hopefully they have more clout with Wouxun than Ed. It will take awhile for China to figure out the warranty problem with independent dealers directly in the US, and they really need a national distribution network to service dealers. At the price point though, these radios, and the Baofengs as well, become throwaways anyway if they break.
