This project implements a VFO and BFO using an Arduino with Si5351 signal generator. You can controll the VFO using an encoder and also a SmartPhone via a mobile application developed …

The solution is to convert the analog input signal into a PWM signal using the ADC and the 16-bit timer/counter1 of the ATmega MCU. The timer/counter2 generates the carrier signal, which …

How to made low noise, high precision, stable RF generator ( with AM, FM Modulation) on Arduino.

May 26, 2016 · Rather than simply setting an AM/FM/SW “register”, the radio chip can be set to one of 41 different frequency bands. Bands 0-19 are FM, 87-109 mHz; bands 20-24 are AM, …

For use in DIY homebrew radio equipment such superheterodyne single/double conversion receiver, SDR, HAM QRP transceivers or RF generator. Load it to Arduino.

VFO/RF generator for use in homebrew radio equipment such as direct conversion and superheterodyne receivers or ham transmitters.

Jan 23, 2012 · This simple project shows how you can make your Arduino into an AM-band transmitter. Wiring: Plug a wire into pin D9.

The test-bed signal generator produces (up to) three unmodulated ('CW') outputs. Once built, it turned out to be surprisingly easy to produce an amplitude modulated output signal without …

An AM/FM/CW Scanning RF Signal Generator This is a low cost readily constructed RF signal generator with a wealth of features which was published in Silicon Chip magazine in June and …

DDS Shield is capable to generate Sine Wave, AM/FM modulated signal and SWEEP Firmware allows selecting and configuring frequency of the clock generator through the user menu …
