[Elecraft] P3 Not Zeroed

[Gary Smith]

This may be too simplistic or doesn't 
address the OP as well as it could but...

I do have an external 10M reference, a 
GPSDO and use that to keep the K3s in 
proper frequency adjustment. That said, 
the instructions in the K3 or K3s manual 
address how to zero beat a known frequency 
source like WWV.

Once the K3/K3s is adjusted to be 
accurately on the exact frequency (ie: 
15.000000). I then go to the P3 and at the 
narrowest "Span" option on the P3, select 
"Ref Cal" from the menu button. and move 
the signal; till it is at dead center on 
the screen, right in the center of the 
15.000000 MHz signal, right at the center 
mark.

I then tap select and this returns the P3 
to normal function. This leaves me with a 
monitor that shows exactly where signals 
are and when I use the marker function, it 
lands that chosen signal dead center and 
the K3s reflects it as well as the P3.

Nothing like a cool smoothie on a hot 
day...
