Do digital receivers get discussed here much? I am working on a receiver
for the WWVB signal at 60 kHz and am looking at a very low power all
digital design in an FPGA. Of course some aspects are still analog such
as the antenna. I have been reading about loop antennas for low
frequency work. I don't plan on having an analog amplifier unless it is
needed. I may be able to sample the RF signal directly and use
processing to boost the signal out of the noise.

Has anyone done anything like this? Right now I am looking at how to
synchronize the sample rate with the carrier so that I can accumulate
the signal in a coherent manner.

Any pointers on where I could find more info?

It looks like I got a reply to this post, but something goofed up in my
reader or the server and instead of Rob's message I see the twice
