[Elecraft] CW PTT

[W3FPR - Don Wilhelm]

Frank,

With the K2, the only good reasons to use any form of PTT on CW is if one
has to switch something like a slow responding amplifier or a VHF/UHF
sequencer that takes a substantial amount of time to complete the sequence,
or SO2R operation using PTT steering.  For most applications neither of
these conditions apply - the antenna is connected directly to the K2 and the
K2 handles all the T/R switching electronically inside the box.  Even if you
have a linear that you must switch in-line to transmit, the K2/100 amplifier
keying output (or the add-on K2 amplifier keying partial kit for the QRP K2)
will properly switch any amplifier that has a reasonable switchover speed.
If you happen to have an amplifier that switches slowly, the best answer is
to speed it up, or if that is unacceptable, add a CW PTT mod to your K2.  I
have described how to do that on my website www.w3fpr.qrprqdio.com (or the
mirror at www.qsl.net/w3fpr).

Don W3FPR
