[Elecraft] ERR TXF

[Bob McGraw K4TAX]

Normal for most radios due to carrier frequency and receiver offset for CW.  Elecraft is not the only that does it this way. 

As filters with reduced bandwidth we find that group delay increases. With this CW wave shapes become a difficult task.  Wider filters are much easier to generate good quality CW elements.
