K2 and WINMOR

[Chuck Teague]

Is anybody running WINMOR with a K2 and SignaLink?  If so what are your
transmitter settings in WINMOR  and how are you keying the K2?  If I try
using my com port for PTT it does key, but it also steps the radio to the
mext mode, which is problematic.  Any insight would be appreciated.

  Chuck,

That sounds like WINMOR is issuing mode commands along with the TX
command that are not compatible with the K2 Programmers Reference.
I would suggest you take that up with the WINMOR author.  If he states
that WINMOR implements K2 support, that should be brought to his
attention.  If he is only implementing Kenwood compatibility, there are
some command sequences that work OK with Kenwoods, but do not work with
the K2.  Compatible does not mean equal.

In the meantime, you might want to consider another way to initiate
transmit on the K2.
The "simple one transistor keying interface" comes to mind.

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.
