[Elecraft] K2/Writelog interface

[W3FPR - Don Wilhelm]

My thoughts exactly - even though Writelog provides a PTT output, it will
withhold keying until after PTT time - and the K2 will not care - it waits
until it sees a closure on the key contacts to transmit anyway.

The K2 PTT input is only a PTT input when in SSB mode - it is the DOT input
line when in CW mode.

In cases like SO2R operation where PTT steering is being used, there will be
a problem unless the key line is also steered.  One solution is my CW PTT
circuit which may be seen on my website www.qsl.net/w3fpr or the mirror at
http://home.earthlink.net/~w3fpr.

73,
Don W3FPR
