As a personal project, I made a very simple AM transmitter with an idea from an online tutorial, using a 1 MHz crystal oscillator (plus power source, antenna, breadboard, etc.).
However, when using an 8 inch wire for the antenna, it is only picked up over a couple feet. How would I make it transmit a longer distance (about 1-2 km)? EDIT: Not 1-2 km anymore, but maybe 50 ft. Either way, I want to understand how it is possible to extend range.
I'm kind of new to electronics and can only understand simple circuits and components like transistor or capacitor, so my online research for this question left me confused. One site mentioned that a good ground is most important for range. If this is true, how do I do this?
Also, I understand that in some countries, there are rules and regulations regarding AM broadcasting. I am doing this in a location where I confirmed that it is okay to do.
Thanks for help!
