[Elecraft] Why is my K3 off frequency?

Or everyone check in using an Eico 753.

Skip,

I agree with all points you have  made.  

Add to the check list the offset in the K3 Filter setup, verify it is set correctly.  On 5 pole filters,, i.e. for SSB the standard 2.7KHz filter, allows an offset setting range of 0.00 to +- 9.99KHz (in 10Hz steps).  The same check would apply to the 8 pole filters, which should be set to 0.00.  These offsets are used by the f/w to set the operating frequency and proper carrier point on the filter slopes.

Furthermore, I don’t understand why the NCS isn’t using his RIT, or operating in split mode, to “chase” stations he perceives to be “off frequency.”  I think back to the past when no one had a digital frequency display to “get within” a couple of Hz of the desired frequency.  Maybe he should be required to use a Swan 350 for a week or two??
