Lynn,
We don't have to worry about processorpower. The hardware is already
there and still developping. And Yes, sampling up to 6m is possible.
Apart from that, the interfacing from the machine to us humans can
certainly do better with some innovation (new ideas) as well.

Consider for a moment an SDR with no analog filtering at all.
How wide would the passband be? Are we going to cover everything from
MF to 6m?
The A-D converter is going to have to convert everything coming in,
and the DSP is going to have to sort out what you want out of
everything coming in: broadcast, other services, noise 50 MHz wide,
and who knows what else.
I'd rather have the DSP concentrate on a smaller bandwidth signal, and
have the processing power available for the few MHz I care about at
any given time.
