Thanks to Tim, N8NQH for sharing a possible 60-cent fix for the loss of memory problems plaguing some Wouxun radios. He’s created a great little resource page for those looking to tackle this repair. According to him, the problem is a little 8-pin DIP surface mounted 24C64 serial memory IC.

Please note, however, that he makes it very clear that this repair is made at your own risk! Your mileage may vary, but at least it’s a possible starting place.

  • Craig - N7LB:

    Ordered a few of the 64KB memory chips today, but also ordered a few of the 128KB memory chips as well (since the pin-out is the same).

    I don’t currently have any Wouxun radios that are giving me any problems (knock on wood), but better to be safe than sorry.

    I wonder if I use the 128KB memory chip if that will allow more than 128 memories to be stored in my various KG-UV3D and KG-UVD1P radios? Any ideas folks if that is doable, or is that going to be blocked by the various software that writes to these radios for programming the frequencies in the first place?
