Защото (може би) само Нощното време получавате Честота на радиостанциите около вашия регион.
Дълги радио вълни (Khz, Mhz) през нощта, се
отразяват от слоя Ionosfer до земята.
Because (maybe) only Night time you Receive Radio Station Frequency around your region.
Long radio waves (Khz, Mhz) at night, get up reflecting from the Ionosphere layer to the ground.
Hello
Dear All.
I built CD4046+Pwer+display, but unfortunately its battery consumption is very high and don't work correctly with 2 or 4 9V. Do you have any suggestion for solving this problem?
What type of battery or power do you propose?
Please see the my panel of Franco's LRL.
There are three LEDs in CD4044 (one LED) + Pwer/display (two LEDs) (attached). Can you tell me what is function of blue LED (in CD4044 circuit )?
In my LRL, beep only is heard by rotating Gain screw, not by Threshold. If possible, please guide me how to caliber the LRL in real environment.
