[Elecraft] Difficulty with K3 Utility RS232 Interface

[Don Wilhelm]

Tony,

I believe your statements confuse the issue.

The K3Utility versions are not related to firmware upgrades (only one 
exception that I recall)
AND
A saved configuration file will NOT reload a previous version of the 
firmware - it will only reload menu settings, like AGC settings and such.

So ... in the event of a firmware upgrade failure, a saved configuration 
file will be of no benefit for getting the K3 operational again - the 
firmware must be loaded before a configuration can be restored.

Firmware loads do not change menu entries and setup data!
Configuration restore only restores menu entries and setup data!

73,
Don W3FPR
