[Elecraft] K3 - qsk keying loop

[Don Wilhelm]

Barry,

For amplifier keying, the K3 has an adjustable T-R delay that is very 
much longer than that provided by the K2.  It may be easier to use that 
than fooling around with the external TX inhibit function.
The TX inhibit is more useful to folks who operate VHF/UHF with a 
sequencer to switch a chain of preamps and antenna mounted gear between 
TX and RX - it can also used to steer the keyer input to one of 2 
transceivers in SO2R setups.
