[Elecraft] K3 PTT CW

[Alexandr Kobranov]

Hi Paul,

this is what I discovered and described on

http://www.zerobeat.net/smf/index.php?topic=215.0

There are some possibilities that later after more important changes 
there will be some change in firmware to set KEY OUT as "pure" PTT out 
port. (I hope so).
For many oparators running special and complex system is RX/TX 
switching by hitting the Key not so comfortable :-(
Now I have ready small switchbox to activate PTT and Key (using K3 as 
EME main tranceiver on 1296MHz) to avoid unwanted keyng of all the 
line of relays in transverter(-s) and mast preamplifiers.
During digital mode there is PTT via RS232 port running but is better 
to remove Key at all from the RIG :-)

73!
