A simple, cheap, tiny, rock steady 3-30MHz VFO Designed by sv3ora. The minivfo (below) used as an RF signal generator and combined with my MCU-free frequency counter (above) The minivfo internals. In the past I have built and tested many crystal oscillators for my projects.

Retro-VFO A Si5351A/MS5351 100kHz lower limit Quadrature Clock Generator with Retro Rotory Dial Using a 240x240 dpi 1.54 inch ST7789 TFT Display. Added a Arduino Nano code example, quad.zip, to demonstrate just the quadrature output without the display.

10kHz to 225MHz VFO/RF Generator with Si5351 - Version 2 For use in DIY homebrew radio equipment such superheterodyne single/double conversion receiver, SDR, HAM QRP transceivers or RF generator. Feb 28, 2021

2020年12月26日 · VFO will NOT tune in TX. LCD connections for for the LinkSprite 16 X 2 LCD Keypad Shield for Arduino. Change as necessary for your LCD. IF frequency is positive for sum product (IF = RF + LO) and negative for diff (IF = RF - LO) VFO signal output on CLK0, BFO signal on CLK2 */ // Only leave one uncommented for the display you wish to use //# ...

ARDU-5351 mini VFO (no display, frequency announced in CW • One variable frequency output + one fixed output (IF/ BFO) • Easy setup using the Arduino IDE Series Monitor.

2017年2月7日 · ZL1UEM'S Tiny OLED Si5351 Arduino VFO Hugh ZL1UEM has come up with a very creative way to take maximum advantage of the small size of the Si5351 board, the Arduino, and the OLED display. He even has the rotary encoder in there.

10kHz to 120MHz VFO / RF Generator with Si5351 and Arduino. This is a project of a VFO (variable frequency oscillator) for use in homebrew equipement such as Direct Conversion and Superheterodyne Receivers or Ham Transmitters. Can be used as RF/Clock generator too. Operation range from 10kHz to 120MHz.

2017年2月2日 · I’ve built a kit Digital VFO with pre-soldered surface mount parts and burned-in firmware, but this was to be a scratch build with Arduino Nano, C code with modifications, and a Silicon Labs si5351 PLL clock generator on a breakout board.
