[Elecraft] K3 Strange power switch behaviour

[Stephen Prior]

Sorry, but I jumped the gun a a bit with my last post.  I have now turned
the alarm off and normal behaviour has returned!  I find it odd however that
the K3 should behave in that way, in that with an alarm set it is necessary
to remove external power in order to get the radio to turn back on again.  I
set the alarm last night, but it turned off normally then!

I have just set the alarm again - all behaving perfectly now!  Very
strange...

I'd be grateful for a comment from Aptos!
