[Elecraft] K3DVR vs CW Memories

[Joe Subich, W4TV]

Be careful.  If you are using an interface that provides a
hardware PTT - serial port RTS, parallel port PTT or a WinKey
based keyer - you will almost certainly have problems with
PTT hanging if you add PTT by "software command."  Use of
both hardware PTT and "software command" has been reported
to result in "stuck PTT" with several transceivers including
the K3 - and with multiple logging packages.  The solution
has always been to use only one type of PTT (generally hardware
which is more reliable).

It appears that more than one transceiver will ignore the
opening of an external PTT line if it happens within a few
milliseconds of a software PTT OFF command but also ignores
the software PTT OFF command if hardware PTT is asserted.

73,
