[Elecraft] Rx-In/Out used for exteranl SDR Device?

[Pete Smith N4ZR]

Through off-reflector correspondence, it appears Bob has a point.  On my 
K-3 (un-updated), I have a Mini-circuits splitter between the RX Out and 
RX In jacks, feeding an Airspy HF+ to support the N1MM spectrum display 
window.  Using an XG-3, I see about a 3 S-unit drop in signal level when 
routing through the splitter, instead of the 3-4 dB I'd expect.  I've 
tried another splitter, with identical results, so I have no idea what's 
going on.

73, Pete N4ZR
