[Scott Traurig]

Hi Joe,

Would you please clarify: is there no longer a way to assign RX2 to any but
ADC1?

The reason that I ask is that sometimes I want to use both RX1 and RX2 both
on ADC0, for example to receive two different bands on WSJT-X with my main
antenna (I believe a lot of folks do this). Is this no longer going to be
possible?

On the other hand, sometimes I want to use RX1 on ADC0 and RX2 on ADC2 so
that I can compare which of my two antennas is better for receiving
(spatial/polarization diversity with MultiRX, not to be confused with the
phase coherent "diversity" function).

Thanks,

Scott/w-u-2-o
