Diy shortwave radio.

Two shortwave antennas that are cut to vibrate at the same frequency will behave like the two tuning forks in my example. For example, the Radio Marti shortwave broadcasting station's antenna will vibrate at a frequency of 11.930 MHz (11,930,000 times per second). That radio station broadcasts in Spanish from Miami, Florida.
