[Elecraft] K3 TX delay

[Don Wilhelm]

If one insists on using an unmodified slow amplifier, yes a sequencer 
would help if the use of the K3 TX Inhibit is used to delay the RF 
output.  Use of that may 'chop' the leading CW elements or initial 
syllables on SSB and other audio modes, but it can work for the benefit 
of preventing hot switching of the amp.

Given that you would have to build or purchase the sequencer in order to 
accomplish that feat, I would suggest that doing a QSK mod to the 
amplifier would be the better solution - resulting in good QSK as well 
as reducing the 'relay clattering' in the shack.
