[Elecraft] preamp for using an SDR as a pan adapter

[Fred Massey]

Good afternoon,

I have successfully connected my QSR-1 to my K3s if-out, and immediately
noticed the signal strengths showing on the QSR-1 were much weaker.  I
probably have an early K3s, so the if-out signal strength is even weaker.

Any recommendations at a good preamp to use?  It seems like 20db is what I
need:
