K3 and the digital modes

[Lynn Lamb, W4NL]

Thanks,

For the many who responded to my question on hook-up for the K3 using the
digital modes, THANKS.

It works with MixW using the two cables from the in/out of the K3 to the
mic/speaker on the computer along with a serial cable for rig control.  Once
I figured out that 'line in' had a gain control automatically selected when
'main/mic sel' was in the 'line in' position!  It's where we normally adjust
the mic gain control.   Neat.

I placed this in PF-1 memory which makes it easily to select when moving
back and forth from digital to CW/SSB.  And using the K3 at about 2.5 watts
into a THP SS amp at 10/12 watts on the digital modes, everything runs very
cool.

It's a learning process but with good help here on the reflector, it was
possible and again thanks for the thoughtful help.

Side bar:  The dual PB feature for CW is great and thanks to Ralph, K1ZZI/4
for calling that to my attention.  I still can't believe all the goodies
this rig has.

CU, lynn W4NL

Note my query in square brackets.

I'm about to set up my K3 with my computer sound card for WSJT
(DATA A mode) operation. You seem to imply above that it is
necessary to retweak the Mic Gain / Line In control every time you
go from SSB to DATA A and vice-versa. I would think the setting
for Line In would be remembered for the DATA A mode, once set. Is
this not the case? Is it necessary to adjust either Line In or Mic
Gain when switching back and forth? I sure hope not...

The Line In and Mic Gain settings are remembered separately, Bill.

Hope to work you using WSJT (assuming you mean JT65A on HF, or even WSPR QSO mode.) I'm still trying to figure out how to use the software, though. The UI is not exactly intuitive!
