The shortwave AM radio bands are above the normal AM commercial station frequencies and are separated into bands associated with the approximate wavelength of that band. The radio receiver designs are similar to commercial AM radio in that they use an IF of 455 kHz in a Superheterodyne receiver. For a station broadcasting in the 49 m band (5.8 to 6.2 MHz), select the required minimum to maximum LO frequency range. Question 4 options: A) 5.745 to 6.255 MHz B)...
