It is impossible to interface any radio into an existing station
using existing equipment that is based on asserting some form
of PTT if that radio has no PTT, full stop.
The typical suggestion from Elecraft community of adapting
_everything_ to accommodate the K2 when this is not
necessary with any other radio since before even my father's
& grandfather's SX-71/Viking 2 combo I suspect will not meet
with much acceptance here.
Even interrupting the key lines is something that is unacceptable
for SO2R - everything is done based on PTT & positive control
of RX/TX state.
I'm curious - who does _not_ use PTT for SO2R for serious
operating on CW? Perhaps we could hear from folks like K5ZD,
KQ2M, etc.
