[R-390] SE-3 like functionality

[Tisha Hayes]

If you break the SE-3 down into the basics it has a good PLL, filtering and
audio amp. All of those elements have been well documented for several
decades (with solid state devices). The SE-3 is very nice in that it is a
single solution pulling together all of those things into one package.

It would not be difficult to design an equivalent product. You could do
much more with an SDR device attached to the IF output of the receiver
where you could let processing power down-convert, demodulate, filter,
etc...
