[Elecraft] KRC2 Decoder Problem

[Don Wilhelm]

Walt,

It may be that you need version 1.6 of the KRC2 firmware - but I will 
wait for Jack Brindle to answer with certainty.
The last I heard is that the release of version 1.6 was delayed by the 
late discovery of a minor bug.

Yes, 6 meter support was reported to be available in version 1.5, but I 
think that same bug which delayed 1.6 may be the culprit.  Jack will 
likely respond with better information than my "hearsay" recollections.

73,
