[Elecraft] 500Hz Filter Offset Question

[K9MA]

It looks to me like you still have to set the offsets. See manual. It 
doesn't appear there is any difference between the K3 and K3s as far as 
filter offsets.

When I set up my K3, I tried to get the 200 Hz filter offset "just 
right", so the noise would sound exactly the same in USB or LSB (CW or 
CW REV). I found that the filter drifted around quite a bit with 
temperature. So, if you have the narrow filters, let the temperature 
stabilize before setting the offset. Wider filters are much less critical.
