Hi Larry,

       HKW Electronic in Gremany sell a range of Receiver Modules and 
Decoders for 77.5 KHz, 60 KHz and 40 KHz. They list a decoder for WWVB, but 
do not seem to have an agent in the USA. See http://www.hkw-elektronik.de/ 

       I have used the 77.5 and 60 KHz versions of their receivers and the 
sensitivity is excellent. You can get problems from Radio Interference in 
Urban surroundings, particularly during the day when the signal is weaker and 
also from computer monitors. Local lightning can also cause problems, but 
this tend to die out during the night. I have tested the response at 2000 km 
range and got good daytime signals in mountain surroundings which had low 
signal levels, but were free from RFI. The 60 KHz Receiver Module MK68 + MK72 
retails at about US $34 + Tax from www.maplin.co.uk They may be cheaper in 
Germany.

       Regards,

       Chris Chapman
