[Elecraft] K-3: AFSK-A switching to FSK-D

[RLVZ at aol.com]

Hi Guys,

I'm running AFSK-A on my K-3 but it's often switching to FSK-D on  it's 
own.  I thought the once I maually set the Mode  to AFSK-A using the "DATA MD" 
button that the K-3 would stay put on AFSK-A  each time I returned to that 
band.  If I change band and return it's  back on FSK-D.  I notice it switches 
from AFSK-A to FSK-D even when  operating on the same band and clicking on 
a Packet Spot.  
 
Is there something else that must be done after I select AFSK-A with  the 
"DATA MD" button to store this in memory?
 
Thanks!
