[Elecraft] SDR-IQ

[Joe Subich, W4TV]

Unless you have performed the IF Output buffer gain modification
<http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf>
or use the Clifton Labs broadband buffer amplifier between K3 & SDR-IQ
<http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf>
what you see is entirely normal.

The unmodified K3 IF output is approximately 17 dB lower than the
RF signal input level.
