Based on a Raspberry Pi Pico microcontroller module, the AM Transmitter can transmit on 32 frequencies in the AM band, from 500 kHz up to 1.6 MHz in 32 steps of approx. 35 kHz.\u003c\/p\u003e\n\u003cp\u003eThe frequency is selected with a potentiometer and shown on a 0.96\" OLED display. A pushbutton allows toggles the transmitting mode between On and Off. The range of the transmitter depends on the antenna. The onboard antenna provides a range of a few centimeters, requiring the AM Transmitter to be placed close to or inside the radio. An external loop antenna (not included) can be connected to increase the range.\u003c\/p\u003e\n\u003cp\u003eThe Elektor AM Transmitter Kit comes as a kit of parts that you must solder to the board yourself.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cp\u003eThe board is compatible with a Hammond 1593N enclosure (not included).\u003cbr\u003eA 5 VDC power supply with micro-USB connector (e.g., an old phone charger) is needed to power the kit (not included).
