Have a 0.5dB NF preamp with SMA connectors
Can I configure Flex6600M without the need of an
External Switch Box ( i.e. DXE RTR1-A)

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 

A Big difference on 6meters DX openings
