    Wish Flex could configure software to either configure Rx-In with an XVTR as the Rx-Out

    Flex6600 in a 500Hz BW has a MDS of -137dBm Noise floor means a 10dF NF noise figure on 6meters

    The KX3 in the same 500Hz BW has a MDS of -145dBm Noise Floor means a 2dB NF noise figure
    on 6 meters
