May 3, 2020 · 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. Set middle knob (the course preselection knob) usually marked "Band" in MHz that your receiver is already tuned to. The middle knob will have a range of freq.'s marked in a range of 4 or 5 positions such as 1.8 to 4 MHz, 4 to 10 MHz, 10 to 16 MHz, & 15 to 30 MHz, Chose the MHz, range you are tuned to.This antenna spans a tuning range spanning 3.5 MHz through 40 MHz and thus covers 80 - 10 meters on the amateur radio bands, all international shortwave bands plus the 11 meter CB bands.
