[Elecraft] K2 and WINMOR

[Matt Zilmer]

I'm using RMS Express on a K3 with up to date firmware.  There are
also issues with K3's, where the AP performs a bunch of serial
commands that cause a 300-500 mS delay (probably a band change as seen
by the K3).  So the first TX begins before the last command is
processed, and only the trailing edge of the audio-in is sent.  The
next TX is fine, so are others following.  For the K3, you just lose
the first one.  It could be that this same problem with the AP causes
a different reaction on the K2 (haven't checked mine yet).

For my MARS RMS Winmor node, I have it set up to use VOX.  The rig is
a JRC JST245 (rather dated, but good reliability) that only supports
4800 BPS on the serial port.  This allows frequency control, but isn't
fast enough to use for TX.

If you have a complaint about any of the supported radios in RMS
Winmor, better address them to Rick Muething soon.  He's off on other
projects now, and it's not clear if that group has any sustaining
staff.

For the K2, I'd just use DTR or RTS as a hard-keying line to the PTT.
You might have to put a 2N390x or some other switch transistor in the
PTT path to handle any inversion and drive.
