Elecraft files

The group Elecraft-K3 at groups.io is used to share experiences with the Elecraft K3 line.

Keith @Elecraft sometimes shares "service experiences" including pictures and diagrams.

While groups.io does have a "file share" capability, it seems this is disabled for members of this group, and me trying to reach out to the group admin has not worked.

This "collection of notes" is intended to mitigate the situation and allow Keith (and others) to publish files.

Enjoy!

• Protection diodes in KLPA3 power amplifier
• KIO3B stereo jack--source issue
  If the rear PHONES jack on the KIO3B module does not mute the speaker, but the front PHONES jack does, there may be an issue with jumpers on the KIO3B module.
  The same jumper issue also causes the line-in port not to work.
