[Elecraft] [K3] Data Mode AFSK A Dual PB

[Joel Black]

I am having some trouble - probably cockpit error.

I have not really been working any of the W1AW/x stations on digital 
modes until the past couple of days. Upon reading Fred Cady's book and 
the K3 manual, I find that in AFSK A, I should be able to set the DUAL 
PB. I cannot. I get an "N/A" message.

I *am* in data mode and I am in AFSK A.

I have the standard 2.7 kHz filter and a 500 Hz filter. They are both 
enabled on the Main and Sub receivers for DATA.

I have even disconnected from RUMlog and cocoaModem just in case they 
were causing an issue.

I just reset the K3 and still have the same issue.

I just checked on my KX3 and noticed that DATA A, AFSK A, and FSK D look 
different on the filter display. On the KX3, AFSK A and FSK D look the 
same (DTF - similar to what is on page 32 of the K3 manual).

On my K3, AFSK A and DATA A look the same (no DTF for AFSK A). Have I 
turned a knob or made a setting that has done this? I have to admit, 
until recently, I have only used DATA A with Fldigi, but I have found 
the integration with RUMlog and cocoaModem to be nice. I'm not really 
used to AFSK A.

Any other tips?

Thanks,
