This is my 5mW SOLAR MEPT today.
It is triggered every minute from the reference
station DCF77. The signal has a shift about 10HZ
and remenber a camel when the strenght is enough.
In the picture the antenna is not connected (50 ohms dummy load).
My DSB receiver picks it very well even on this conditions.
DCF77 WORLD
Modifying my 100% Chinese alarm clock , I discovered an interesting world.
At the frequency of 77.5KHZ is tranmitting the VLF station DCF77.
Capturing the tiny time digital code (0-1.5V) , by an optoisolator
I made a qucik sincronization with a microcontroller PIC16F84.
I was able to extract one pulse per mitute , necessary for
triggering my 5 mW SOLAR MEPT.
