[Elecraft] K-1 4-band Availability/Status?

[Don Wilhelm]

Herbert and all,

There is no need for the KFL1 firmware to be open source, it is 
available from Elecraft as a spare part.  Elecraft will continue to 
support existing KFL1-4 boards with parts (except for replacement 
trimmer capacitors) for a good long time into the future.

In other words, even though the board has been discontinued, that does 
not mean support for that board has been retracted.
If I need to repair a KFL1-4 board that has a failed trimmer capacitor, 
I will then replace it with another temperature stable capacitor with 
lesser range an use whatever NP0 or C0G capacitors to restore it to 
working condition.

I have replaced a few of those blue bodied capacitors in the past, but 
the number has been very few considering the number of repairs I have 
done over the years.

73,
Don W3FPR
