[Elecraft] Feature request - Disable Break In on K3

Mike,

I think you mean Keyout rather than PTT -- PTT is an input signal to the 
K3 generated by an external device such as a footswitch..

The use of TX INH does not prevent the Keyout signal from activating - 
it should click the relays and start your sequencer.  BUT it does 
prevent RF from being transmitted which will protect your preamps and 
other things that need to be protected during the sequencer time.
A typical sequencer will complete its cycle in a few tens of 
milliseconds.  If you don't like the Keyout state changing with keying, 
use semi-break-in and set the delay to whatever time period you desire 
to keep the Keyout active between characters, words, etc. - that time 
will depend on your keying speed..

73,
Don W3FPR
