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 ~ Buck k4ia K3 # 101 In a message dated 3/20/2008 11:59:20 A.M.
