[Elecraft] KRC2 Need help with configuration utility

[Willard Myers]

The band map configuration component of KRC2 Utility seems to have, err, “issues.” It works for me with appropriate pixie dust, but I’m using a Mac version of the utility.

Part of the pixie dust involves saving an edited configuration to a file *before* loading that configuration into the KRC2.

Also, note that the KRC2 won’t know what band the K3 is on if you turn on the KRC2 after turning on the K3. That is, the KRC2 is only informed about band changes (via auxbus) when the K3 is powered on or changes bands; it doesn’t poll the K3.

IMHO, your best bet is to lobby Elecraft to apply some resources to the utility software and documentation.
