20Hz Offset between CWSkimmer & N3FJP Amateur Contact Log using SDR BRIDGE & F6300

Have any of you achieved ZERO (0) offset with this combination of software?  Have not found method to net them closer.


Flex 6300

CWSkimmer ver 1.91

N3FJP ACL Series of logs latest vers



The 20Hz offset easily falls within the passband.  More of an annoyance than a show stopper.

    Where is the error indicted?  CWSkimmer does not have the same frequency resolution as the radio.  the FLEX-6300 has a minimum 1 Hz resolution.  CWSkimmer has a minimum 10 Hz resolution.  Therefore there can be rounding effects that show up as a frequency mismatch.  If you are feeding a third-party app frequency data from CWSkimmer, that is where a mismatch can occur based on the "dial" frequency of the FLEX-6000.
