20K-220MHz Superheterodyne Receiver SDR HAM QRP RF VFO Radio Debugger

This is a VFO (Variable Frequency Oscillator) project that can be used for DIY self-made devices such as superheterodyne receivers, DCR s, SDR s or Ham QRP s. It also has bar graph indicators for signal strength (S-Meter) and 20 Band presets. And can also be used as an RF/clock . Features: It has 10kHz to 220MHz working ranges. 0.5PPM high precise Tcxo clock, the frequency is more accurate. Tuning step of 1Hz, 10Hz, 1kHz, 5kHz, 10kHz and 1MHz. Intermediate frequency (IF) offset (+ or -) is adjustable. 20 band presets (shortcuts) for BCB and HAM frequencies. Equped with function mode. RX/TX mode selector for Homebrew QRP s. The bar graph of the signal meter through the ogs input (ADC). It can be used as a local oscillator on Homebrew radio receivers (such as superheterodyne, SDR, direct conversion and Homebrew QRP s). Can be used as a simple RF/clock for calibration reference or clock generation. And also can be used as a common 128x64 I2C OLED SSD1306 display and Si5351 module. I2C data transmiion, only need 2 lines it can be connected to the display, with high stability and accuracy of frequency generation.
