[Elecraft] K3: Using built in PSK?

[Greg - AB7R]

Dave,

Are  you in Data-A mode when using audio based PSK31?  If so, adjust your filter FC
to 1.0.  The BW can be what you want it to be, I normally start mine off at 1.0 kHz.

If you transmit your signal right at 1.0 kHz on the waterfall in Data-A it should 
be the same as when using PSK-D.  PSK-D uses a default of 1.0 kHz.  But it creates 
its own audio tones instead of using an external soundcard.  

If when you are using Data-A you are somewhere other than 1.0 kHz for your audio, 
then no, the PSK-D signal will not be at the same place, it will always be at 1.0 
kHz.  Also, when using PSK-D you do not need to adjust the filter FC, it will 
already be at 1.0 by default.

haven't seen any comments... maybe I am too anxious, but I am also anxious to cure 
this problem- so again, I say:

to notify other net users of external computer problems, maybe so. However when 
monitoring my AFSK PSK31 signal from the K3 on my OII,  I don't see the AFSK PSK31 
signal on the same waterfall of the MixW software. That leads me to believe that 
you can not switch from computer driven AFSK PSK31 to built in PSK D PSK31 because 
they are on different frequencies. Tell me I am wrong and tell me how ot make it 
right.
