I wish to build a radio which can receive a 60kHz, amplitude modulated signal.

What is the simplest circuit that will achieve this?

Assuming a ferrite rod in an inductor/capacitor configuration, how would I tune this setup?

  • \$\begingroup\$ Out of curiosity, what is transmitted on 60kHz carrier? This is such a low frequency. \$\endgroup\$ – Nick Alexeev Feb 15 '13 at 4:03
  • \$\begingroup\$ 60KHz may be wwvb NIST \$\endgroup\$ – Chetan Bhargava Feb 15 '13 at 4:35

Looks like you doing a time carrier for Europe. Ironically there was a discussion early about these types of antennas. Here is an example of a module for time code reception in case that is what you're looking for.

I've just done this. As you want the MSF time code I expect you have a computer to read the result. I used the onboard soundcard and a few meters of wire into the microphone socket, nothing else https://drtonyr.github.io/MSF60decoder/
