5.15.11 - Monitoring radio IF outputs
Many radios have "IF outputs" that you can feed to the input of an SDR. This in turn lets you monitor, with the SDR, what the radio is tuned to, sometimes quite a frequency range around where the radio is actually tuned.
Some radio IFs are "inverted", meaning that the result in SdrDx's spectrum and waterfall will be high frequencies at the left, low frequencies at the right, the demodulation sidebands inverted, and so on. In such a situation, you can →Right-click and place a checkmark in 
L-R Swap , click 
OK, and that will re-invert the IF signal so that SdrDx works normally.
