[Elecraft] Feature request - Disable Break In on K3

[alexandr.kobranov at seznam.cz]

Hi Mike,

if You open some mail-archive You can see a lot of mails concerning this 
behaviour (recognized as strange by some of us) from the first days of K3. 
There is probably no way for solution. So if You have key activated You have
a Key Out activated. There is no real PTT out. Probably this was not 
recognized in design period as a real need and nobody count with some of us 
with more complex systems with VHF/UHF transvertors, premplifiers and a lot 
of relays around :-( 
Yes, there is no RF and You have Inhibit port. But .....

73!

"It would be interesting to learn under what practical circumstances 
someone might offer that the current arrangement is a desired mode. I 
can't think of any, however, that could just be lack of imagination on 
my part.

Until convinced otherwise my vote is with N6ML. CW mode, VOX off, no 
PTT = no Key Out.

Regards,

Mike VP8NO
