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.
