Yes, this would not need to be tunable as WWV is at a fixed frequency. I
have seen a receiver that uses a 10MHz crystal in the front end and then
mixes the signal to baseband then samples it with a PC "sound card". $10
in parts easy
You extract the time in the PC software. I say "PC" but a really low-end
computer like a Rasperry Pi would be perfect for this, maybe over kill but
you'd want the features of the OS to send the time some place
