[Elecraft] K3 Overload from WYFR

Are you sure the K3 front end is overloading and not the LP-PAN system 
(QSD, attached soundcard)?   Are you experiencing symptoms that suggest 
reh K3 front end is overloading other than the LP-PAN display (which may 
be displaying the LP-PAN system, and in particular the soundcard ADC, 
overloading)?

You might try adding an attenuator between the K3 IF out and the LP-PAN 
IF in and see if the overloading disappears. If so, it might indicate 
the LP-PAN system is overloading rather than the K3.

PS - The K3 blocking dynamic range is 20 to 30 dB better than PC-based 
SDRs.  So I suspect you are seeing a weakness in the PC-based SDR system 
rather than the K3, but I've been wrong before! :-)
