I am new to FlexRadio. Running Flex 6500.  I seem to remember turning on the preamp in the past, but, for the life of me I cannot find a way to do it now.  I cannot seem to find it in the documentation either.  Any advice?

In the ANT menu left side of the panadapter display. Useful for frequencies of 20M & up depending on the receive antenna used.

Click on ANT (left side of screen) then select the level of RF Gain you want.

The operation of the RF preamp is addressed in section 25.11 and 25.12, Using the Receive RF Gain/Preamplifiers and Setting the RF Gain/Preamplifiers respectively in the SmartSDR Software Users Guide.
