Lynn,
Some filtering ahead or some attenuation or preamp will be there or
better said: are there. What I meant is that the transceiver of the near
future will use an HF A/D converter, so direct digital sampling.
One of the first widely available RX's (at a nice price) was the perseus
RX. Lots of info on the net about this little RX.
A nice application of this principle is found as a 'web-sdr'. See here

You can even check your own signal with it (if propagation permits hi)

I'm not familiar with the other Software Defined Radios out there, but
I'll bet that nearly all of them do some kind of analog pre-filtering,
then do the heavy lifting in software.
