If your K3 has the KXV3 option installed (a row of 5 BNC connectors just
above the CW and PTT keying jacks on the lower right back panel), then
there are two ways.

1) Connect the SDR to the IF Out jack and tune the SDR to the K3's IF (8215
kHz). You can receive signals in (or near) the same band as the K3.

2) Connect a jumper from the RX Ant Out jack to a splitter, one output of
the splitter to the RX Ant In jack and the other to the SDR, select the RX
Ant from the K3's front panel, and tune the SDR to a frequency on the same
band or a lower-frequency band (signals on higher-frequency bands are
attenuated by the K3's low-pass filters).
