[Elecraft] Uses for K1 MCU?

[Don Wilhelm]

Scott,

I have suspicions that most folks who upgrade the firmware keep the old one
'just in case', but actually, should something happen, Elecraft can get a
new copy of the firmware to you in 3 days or less by Priority Mail should
that prove to be necessary, so I have come to the conclusion that the best
place to put the old firmware is in the waste container.  The 'C' versions
of the PICs are not re-programmable - OTOH, if it has an 'F' designation, it
could be re-programmed for other uses.
