Hi Jamie: The same company makes a number of LF time code receiving products. Their top of the line model combines a ferrite loop antenna, made to have very specific properties, with a three band receiver that resonates the antenna at either 40, 60 or 77.5 kHz by switching caps. The included CPU can decide which frequency is active and then decode it to make a clock that works with any of the standard signals.
The big problem they had was the capacity of chip caps change when they are soldered making it very difficult to choose the proper caps. See: http://www.prc68.com/I/Loop.shtml I have a couple of the no CPU units on order in the hope that the output signal has a relationship with the signal strength. If that's the case then they can be used in developing an antenna. Have Fun, Brooke Clarke http://www.prc68.com James R.
