K1 C78 for 80 Meters

[David Dietrich]

Hello All,

I hope that those of us in the US are enjoying the holiday weekend.  I have a question about the
C78 capacitor for 80 Meters on the K1.  As I said in previous posts, My K1, once built, will be
capable of all six bands.  With that being said, If this capacitor is to help with 80 Meters, what
does it do to performance if I don't have the band module that contains 80 installed?  This is
coming from an alignment and operational standpoint.  Any clarification on this would help.

Thanks,

David

True, C78 and RFC8 are normally included only with the 80m filter board parts, but they are appropriate for *all* bands.  It would be better for Elecraft to simply supply them with the basic K1.

So have no qualms...even if you never use 80m.  If you have them, install C78 and RFC8 when building the RF board right from the start.
