[Elecraft] K3 TX DELAY

[dave]

One thing that hasn't been mentioned so far is that the WinKeyer has a 
separate PTT out that has a programmable delay before initiating the 
CW. This will allow the needed delay without affect the sent CW in any 
way. Use one here, works well.

Used the scope to measure the actual settling time of the open frame 
relays (about 30 mS is needed to full settle). Measured the K2/K3 
delay then added enough with the WinKeyer to insure no hot switching.
