Paul - what a great idea, I wonder why -I- didn't
think of it? !!!

The K3 is so versatile. Everthing I try provides an
afternoon or more of radio enjoyment. There are more
buttons on brand I, Y and K, but I never had as much
fun trying things with those sets. 

I did something like this QSK split with the TS480,
but on CW it still did not provide exactly what I was
looking for. 

The K3 does not save the SPLIT setting to my memories,
seems like it should. No worries, I am just a button
pushing cowboy. ;-)

Great suggestion.

I tried something last night that may be of interest
to some CW ops. 
Although most of us are always in search of ways to
narrow CW bandwidth, 
there are times when listening to CW is made more
enjoyable when the 
receiver is allowed to open up a bit, especially with
AFX activated.

In order to engage in wideband CW reception with the
wider crystal and DSP 
filters, press SPLIT, then A=>B.  Set VFO A for either
LSB or USB.  Then, 
set VFO B to CW.  Next, press and hold the SUB button
to link VFO A with VFO 
B.  The CW offset can be made to match the sidetone
frequency by setting VFO 
A and B to slightly different frequencies (difference
being the side-tone 
frequency).  I stored my settings into memory so I
don't have to go through 
all the gyrations next time.  With this approach, the
rig is transmitting CW 
on VFO B, but listening in either LSB or USB on VFO A.

It's important to set the Rx frequency on VFO A up by
the offset amount 
(e.g., 600 Hz) for CW LSB receive, and down by the
offset amount for CW USB 
receive.  My tests show that QSK performance remains
super-fast and is not 
affected with this procedure.
