Conrad DCF77 module here works ok on MSF. I had to swap xtal and aerial.
If you can find the type of receiver chip and see the xtal and aerial 
connections it's probably worth looking up if chip will pickup WWV. I
can't find my Conrad data but I think that also does WWV (output is
just demodulated carrier).
