[Elecraft] Serial port keying via the K2 (Logger32)

[Charles Greene]

John,

Depends on the program.  Most use serial port keying; works even if you are 
using a USB-serial converter which I am doing right now.  For example, MixW 
lets you select either DTR or RTS  for PTT or CW, but some programs use one 
for CW and one for DTR but not both for both..  I don't use DRT, because at 
the time I made up my interface one of the Windows operating systems DRT 
keyed on startup.  You can get around this by turning off the K2 on 
computer start up.  I am making up a new interface and diode "ORing" both 
DTR and RTS to both the K2 keying line and the K2 PTT so it will work no 
matter which program I use.  The K2 key also needs to be diode ORed to both 
the dot and dash connections per K2 manual and the K2 menu setup made so 
the computer keying will work.  I have a paddle plugged to the interface 
that bypasses the diodes on the CW keying circuit so the paddle works or CW 
keying works, which ever gets there first.
