[Elecraft] Help with K3's KDVR3?

[N2ZDB at aol.com]

I am not able to record in all the bank memories. Bank 1 memories  1 and 2 
are used and I am not able to record in 3 and 4 even though I have tried  to 
record 15 second messages.....when I go to play them back it just shows  
"END"!
 
Do the bank memories have there own memory separate from the AF RECORD  
memory? If you record 90 seconds of REC memory does it "use up" bank  memory???
 
Thank you,
 
Michael
