Hello,

Beginner. A few very basic questions please, that I could not find in documentation.

a. My understanding is that the RF Gain is (only) set by the RFATTEN slider.
That there is no other RF Gain adj. True ?

And that the slider has no effect if the the AGC is set to ON. Is this correct ?

But, if I do move it, I can attenuate more. So, how does the slider
interact with the automatic AGC ?

b. For “normal” listening of 30 MHz and below, do you folks suggest a slow or a fast setting for the AGC ? Above 30 MHz ?

c. Where is the volume adj. for audio output ?

d. When would one use the synchronous am detector option ? All the time, or...?

Much thanks,
Appreciate the help,
Bob

I hope that the following may help:
?B: Slow works fine for me below 30 Mhz
?C: Volume control slider is the yellow bar at the botoom of the RX Ctlr pane
?D: See P30-31 of user manual (easy access via the SDRuno MAIN panel under "opt." It is the preferred mode for AM.
I'll leave the rest to the experts...

Hello Bob,
Regarding the questions on AGC and RF gain control, I recommend that you have a read of the following application note:
