[Elecraft] K3 TX-INH

[Don Wilhelm]

Stewart,

The K3 will not emit RF when the TX INH is active.  But it will stay in 
a TX state and does not go back to RX.
To do as you want, you would have to use KEYOUT to start a timer whose 
output is with TX INH inactive and after some period of time would turn 
TX INH on and stay that way.
