Add on AM Modulator has High-Bandwidth - 09/11/98 EDN-Design Ideas The simple circuit in Figure 1 is an add-on modulator that converts the output of a continuous-wave (CW] source to either an amplitude-modulation (AM] or a suppressed-carrier-modulation (SCM] format. Because the circuit has unity gain and 50 Ohm input and output impedances, the CW generator's....file has many circuits, scoll to find this one....

|AM Farm Radio Power Supply - Prior to the 1950s, many rural areas in the US had no electricity. Many companies sold battery operated vacuum tube radios for use in these areas, the radios are commonly called Farm Radios. Farm radios are often available at very reasonable prices and can make a good restoration project.... [G. Forrest Cook]|
