[Elecraft] Using SDR Play with KX3 Ocsilator Noise?

[Bob McGraw K4TAX]

As I have found, it may be necessary to set the LO to an offset value 
from the TUNE frequency of the SDR Play receiver.   I use HDSDR for my 
software with the SDR Play.  The feature is in  the F7 Options menu, 
look for Misc menu options of HDSDR.   Also, it may be necessary to set 
the DC Removal to a value in F7 Calibration menu. A bandwidth of 5 to 25 
Hz seems to work OK.
