Hello
There is one thing that has to be taken into consideration:
The SDR QSD as in softrock is radiating a strong signal at the center
frequency and that will get injected into the IF if using it as a
panadapter.....
The TimeMachine has an amplifier at the input which isolates much of
the interference from the LO but I moved the LO some KHZ out of the
high selectivity filter that comes later in the RX (in my case a
K2)
