MixW settings for K3

[Mike K2MK]

I use MixW for AFSK RTTY and I thought I had successfully set it up. But
something unusual happened. I noticed that if the K3 was in CW mode when I
started MixW the K3 immediately began transmitting as if the key input was
activated. If the VOX was off I would still have the key closure (as
evidenced by the tone in the monitor) but of course it would transmit. While
this is happening you can't change the K3 mode. You have to disable CAT on
MixW (or quit MixW) and then change the K3 mode.

The problem was my MixW settings. I had the RTS and DTR set for Always On. I
checked the MixW reflector and found the suggested settings of:
RTS set to PTT
DTR set to CW
MixW now works properly in digital modes and will not erroneously activate
transmit if the K3 is in the wrong mode. It does transmit CW properly in the
MixW CW mode.

   YES!!  I had the same problem (PTT always asserted) come up
   suddenly with the RigBlaster Plus interface to my K2.

   I sent the interface back to WestMountain, fearful that the
   transistor controlling the PTT output had failed.  They
   returned it (three weeks later counting round trip shipping)
   stating that it was operating correctly and that there may
   have been a change in how Win XP handles ports (it started
   doing that after several Win XP upgrades were installed).

   I changed the setting of the port in MixW to those that you had
   posted, and lo-and-behold I was back on the air just in time
   for the RTTY contest, which I did not participate in!
