[Elecraft] Difficulty with K3 Utility RS232 Interface

[Dick Dievendorff]

I found an unchecked use of an MCU command (IC) that was introduced in MCU
revision 2.48 in the Save Configuration code.

I have sent a private (untested by Field Test) version of the K3 Utility
that removes this dependency to the people I'm aware of that were waiting to
save their configuration before upgrading from a very old MCU revision to a
more current firmware level.

I apologize for the oversight.

I have added a save config test using MCU 2.02 to my pre-release test suite.

If anyone else is "stuck" with an old MCU and feels it important to save
their configuration before upgrading, please send me a note.

The fix will be part of the next K3 Utility general release after it
completes Field Test.
