[Elecraft] OK... I give up on what is happening...

[David Cole]

Hi Ron,

I am not sure it is a serial problem, in fact I would probably bet money
that it is not...  Here is something new to ponder about this that may
help you...

If I go to the "CW is LSB" option in MixW, and assert it, all behaves
fine, (both waterfall and signal track as I turn main tuning dial), on
80, through 17 Meters, if on the other hand I then switch to any band 15
through 10 meters, I get the action where as I adjust the frequency up
using the tuning dial on the K3, the "dial", (in the waterfall), on
MixW, tracks fine, (as it does on the lower bands), but the signal moves
in the opposite direction, so it looks as if the frequency of the signal
is changing as observed by MixW.  

If I then uncheck the "CW is LSB" option, the actions are reversed--
that is to say, that all works as expected on 21 through 10, and the
reverse behavior is on 80 through 17 Meters...   This baffles me
totally...  If it happened with the change boundary at 14 Mhz, (20
Meters), I would say it is the rig changing sidebands...  But it happens
on 15 Meters, working just fine on 20...  

So my first thought was that it was just the radio changing sidebands,
so I set the MixW as "CW is LSB", all works on 80-17, I go to 15, see
the reverse behavior.  I then then hold down ALT for changing to the
opposite sideband...  The change happens, but the reverse and lack of
tracking behavior continues, just on the other side of the waterfall.  

There are some very odd things about the K3 I still don't
understand...  

If I load up FLDigi, I get the reversed behavior on all bands...  

Maybe the K3s are possessed, this baffles me totally...  At the risk of
sounding frustrated, this did not happen on the Pro III, or PRO II I
had... The serial port was also able to keep up, where I suspect the K3
is processor bound and can't keep up with a 38K data stream.  

Maybe you are right, somehow this is serial related, but I can't see
how...  I do have two ongoing serial issues:

1.  During frequency load I get timeouts, I would not expect this.
2.  The K3 appears to be unable to keep up with the data being sent by
MixW, where the Pro series was able to do both items 1 and 2 with no
issues.
