[Elecraft] K3 Test mode not kept while adjusting filter offsets

[brian]

Beware!

I was fine tuning filter offsets with the utility program.   A noise 
generator was attached to the antenna terminals.
The test mode was selected to prevent damage to the generator.

I adjusted the offset and told the firmware program to apply it.
It rebooted the K3.   Test mode was not maintained.

Fortunately I didn't hit the key or anything so no damage.
