  • Nov 24, 2015. #4. You just need a 60kHz low-power oscillator (single op-amp or transistor using RC or LC) followed by a "modulator" that uses a Fet switch as part of an voltage-divider that either puts out full signal, or 0.141 of the full signal (switchable attenuator) . The gate of the FET will be controlled by your Arduino port pin.
  • Nominal frequency: 60KHz±300Hz. • Receiving frequency: 60KHz. ⇒ DCF receiver module with antenna. Antenna size: AR8x60mm/High Q. • Board size (without antenna) LxWxH: 22x13.5x1 mm. Note: The single-frequency module cannot switch between different frequencies of DCF/WVB/HBG/BPC.
  • To resonate the antenna at 60 kHz, the total capacitance must be: 60 kHz = 1/ (2π · sqrt (6.9 mH · C)) → C = 1050 pF Which means an additional 1050 - 83 = 970-ish pF should do the trick, which is about what you'd expect from the 64 kHz resonance with the 900 pF cap above. I paralleled pairs of caps until it resonated at 59.9 kHz.
  • Rescue Electronics Surplus. The WWVB 60 kHz Low Noise Ferrite Loop Antenna is 24 " long and housed inside of the white weatherproof PVC pipe. Coaxial cable losses are so minute at 60 KHz, that the preamp if needed can be located inside away from the elements, close to the power supply, with easy access. should it ever need replacing.
