[Elecraft] Re: K3 Key-down on power-up [Solution?]

[Don Wilhelm]

Wayne,

Given the situation, reasons, and consequences, I believe something like 
what you suggested would be the best solution.  If you can extend the 
time beyond 'the first couple of seconds' (enough time to change the 
menu or power down), that would be helpful IMHO.
