[Elecraft] New K2 - two bad encoders

[Don Wilhelm]

Lou,

The encoder itself is the same one used in the K3/K3S, so I think if 
there was a bad batch of encoders in the Elecraft stock, it would have 
been noticed and quickly corrected.

However, the board to convert the pulse count of that encoder to that 
needed by the K2 is suspect in my mind.  It is 'firmware' and I suspect 
that there may have been some unprogrammed ICs made their way into the 
K2 encoder assembly packages.  Of course, that remains to be proven, it 
is just a guess on my part.

Continue to work with support, it should be resolved soon.

73,
