[Elecraft] test mode indication

[Gary Lee]

How about a couple of beeps when ptt is pressed if in a phone mode, and 
something, I'm not sure what for cw.  Maybe a drastic change in sidetone 
frequency.

This solves the problem for a blind operator, and brings another sense into 
play for the sighted to say "HEY, PAY ATTENTION, SOMETHING IS'NT AS YOU 
EXPECT".

I have noticed that many times engaging two senses makes the light dependent 
(hi hi) pay attention.

Please take the humor as intended, its been a long day programming.  But the 
suggestion is serious.
