Any recommendations for a "high-reverse isolation buffer" circuit?

PLEASE remember that you *must* have a high-reverse isolation buffer
between the K3 IF OUT jack and the Softrock antenna input. The
Softrock may have a huge spur at its carrier frequency and its mixer
may not suppress this adequately. So there is a potential coupling
problem (mixer) and radiation problem (shielding). The IF out of
the K3 does not have high reverse isolation characteristics, so you
need to ensure you do not couple a signal at the IF *into* the K3
through this connector.
