[Elecraft] K3 and linear amp

[K4IA at aol.com]

I rely on my MicroHam Microkeyer to key the rig  and amp.  You can set the 
delay in the MicroKeyer.

You can also  insert a half character space at the beginning of your CW 
macros so there is a  slight delay between going into transmit mode and actually 
transmitting.   In the N1MM contest software the appropriate character to insert 
is the  ~

You can still use  the amp by manually activating the transmit switch on both 
pieces of gear. I do  this with one old rig I have. Not the nicest solution

nice for QSK  CW
