For maximum use, one will probably need a multiple display system -
or multiple computers for "radio" plus logger.  Not something one
can do with a $699 Mac Mini.

Do the math with multiple S9+20 (-53 dBm) to S9+40 (-33 dBm) signals
in a 300 KHz RX passband (or even with *no* front end filter as Flex
mentions in their brochure).   The effect is two or three volts peak!
It's not simply an extra 3 dB for each additional signal.

With *measured* broadcast signals in Europe adjacent to and within
40 meters of 0 to +10 dBm on a simple dipole, that's going to be a
problem even with the (optional) bandpass filters for each amateur
band.

Yes, in reasonably quiet locations - without strong local signals -
the Flex BDR will be fine.  However, if one lives close to an AM
"antenna farm" or in a high concentration of active amateurs, the
out of band issue can be severe on 160/80/40.  The bandpass filters
will be necessary, out of band receive will be an issue and contests
with their high level of big signals may be a problem for everyone
with a DDC based receiver. due to ADC overload.

I did not see that ... and I looked for it.  I was told $6K and $7K
by a Flex employee (wearing a Flex shirt) at the booth in Dayton.
