WWVB Reception Using VLF Converter on Grundig G5

Here is a video of my G5 receiving WWVB using a crystal oscillator VLF converter set to 1060 kHz using a 1 MHz crystal. Soon I will be using a 4 MHz crystal like other VLF converters. As you hear this the signal is coming in moderate strength. As you hear the beeps that is WWVB on 60 kHz coming from Fort Collins Colorado using SSB to hear the beeping sounds. Only a digital clock can decode this signal which is in 1's and 0's using phase modulation keeping the clocks accurate at a millisecond. As you see I was able to receive it using the crystal oscillator method and a LM-386 audio amplifier and a box 200 turn loop antenna.

that is ace! can you recomend any schematics for the circuit you did as i am looking to do the same so i can pick up the uk 60khz signal. iv heard a 555 timer can be used with the control voltage line used as the ariel and the oscilator set to whatever frequency you need for picking up on the radio, the output of 555 is used as transmitter but im still a bit unsure of best approach. also heard op-amps can be used but still cant find much info on this kind of approach. =]

@JohnnyX50 I have a schematic diagram in my files, I will be glad to share it with you. It's my own design that uses a radio input or if you like you can use the antenna off the oscillator. just send me your email address to me in the private messeges.

I'd also like the schematic. Nice rig you got there.

I'v a question I hope you can help me with. I have the Pro-164 radio-shack scanner and the scanner has a amateur band that covers 28.0000-1300.0000MHz Frequencys. Can my G-5 S.W. radio pick up frq 146.9700MHz ? The G-5 has frequencys in KHz and I'm trying to find a freq in MHz. I hope you or someone els can help.

Use a VLF receiving converter to help get e.v.p

Glad you were finally able to hear it in real time. You can get even better reception if you take one turn of wire and tape it to the longest wall in the room you listen in. I've noticed that size is more important than the number of turns, but if you don't have a lot of space, more turns is better.
