Fred,
Have you looked the K3 IF Output mod?
https://ftp.elecraft.com/K3/Mod%20Notes%20Alerts/IF_Output_Buffer_Gain_Mod_Rev_A.pdf
If you don't have the 13k SMD resistor or a 1/8 watt 13k resistor, you
can order the kit from Elecraft.

Good afternoon Wes and all,
If I connect the antenna directly to the QSR-1, I get the same signal level
as the K3s. But, when I connect to the QSR-1 to the IF-out, the signal is
about 4 s-units less.
Any ideas...anyone?

I use an SDR-IQ on the i-f output on my (very) early K3S. it works fine.
IIRC,
always a dubious proposition, I did the mod on my original K3 and it
worked well
too without any additional amplification. I think you have another
problem.

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:
