Thanks to "Chappy Happy" for this simple indoor receiving loop antenna for general shortwave/ham radio listening. The antenna covers 5 MHz through 14 MHz. Here are some general comments regarding this DIY antenna.Due to the physical properties of the earth's ionosphere, shortwave radio broadcasts are reflected over the horizon, propagating to listeners hundreds or even thousands of kilometers away. Tube transmitters are available with 100kW, 300kW or 500kW maximum power ratings, which increase the distance at which broadcasts can be received.It is based on Genius idea of T.Uebo / JF3HZB to create virtual Analog rotating dial on Colour TFT screen. For the preparation of this section is used an ESP32 microcontroller, Si5351A I2C Signal Generator module board and 1.8 inch 128x160 TFT LCD with ST7735 chip. A rotary encoder is used to change the frequency.

Basically, the circuit is utilizing 12 MHz crystals to transmit the radio waves. Because of this 12 MHz crystal, the circuit won't float its frequency. Thus, it broadcast its radio waves at exactly 12MHz. Furthermore, The short wave or SW transmitter circuit operates in a shortwave HF band. Hence, it ranges from 3 MHz to 30 MHz only.
