[time-nuts] Ideas for a long-wave receiver sought

[Marc Balmer]

Hi

I want to build a small, cheap, yet precise long-wave receiver which  
can be
tuned from the computer in the 2KHz - 200 KHz range (the intended use
is to receive various time signal stations).

Does a chip for such a receiver exist?  Should I take the SDR route?
I designed a DCF77 receivers some years ago, but I need something
more flexible (and a bit more modern...)
