QDX: Anyone else having a problem with image rejection? #qdx


 

I'm seeing signals from 27 KHz below 14.074 MHZ... strong Morse code signals actually (when checked on another receiver).

I understand why it's 27 KHz, and that image rejection depends on the balance between I and Q magnitudes (IC7A and IC7B outputs).

I thought I'd fixed it earlier by removing the solder bridge on IC7, the problem is better but still there.

Before I start poking around with a scope: Has anyone tweaked their image rejection?
