This is a "cross post" from the PX-888K Yahoo Group. Any comments or knowledge of this planned radio life span?
The PX-888K radios have the family of "suicide chip" that causes failure after it fails. The chip is the 24C32 EEPROM. It is alleged that ALL of these chips regardless of manufacturer will fail as they have a limit to the number of read-write cycles.
This chip is verified inside the Puxing PX-888K Radio. If anyone has any issues please let the group know.
As a refresher: Most Wouxun radios will write out their memory to the 24C64 upon power off and do a read from the same chip upon power on. As a result the chip fails; due to this action after a number of power cycles.
The 24C32 is a smaller capacity of the same chip family. There have been NO cases of this failure as the design of the radio may possibly not be as read-write intensive as the Wouxun radios.

What does this have to do with the VX-3? I notice you tagged your post as "in-reply-to" the VX-3 thread, and also used that subject:

I bet thousands of chirp_users subscribers who don't own a VX-3 will never open this message.
Also, please keep messages related to Chirp. It sounds like this issue is more influenced by power on/off cycles than programming cycles, and is limited to a few specific radios. Please keep discussion of non-programming issues with these radios on their own mailing lists.
