Thanks for the helpful & considered feedback Joanne (this topic & other recent). I'm still on the learning curve with SDR digital technology.

Yes I guess that is what Youssef was briefly hinting at. And Simon's SDR Console v3 software doesn't have centre tuning.
And if I understand/interpret correctly from last message from Youssef the different AGC's & Filtering between SDR# & SDR Console
may yield different results re clicking noise or not whilst tuning, re my citing of previous examples in past messages.

>There is also possibility of rapidly changing signal strengths in high signal environment of experiencing random occasional popping/clicking noise whilst not tuning,
When time permits, if I can find examples etc I may need to take & unload videos - if I'm convinced sufficiently that problem isn't an external noise source(s) AND also whilst
freq wasn't fixed on centre tuning position (given feedback) - more testing required by yours truly.
