HF VFO for Ham SDR QRP Transceiver, 20K-220MHz RF Generator

  

HF VFO for Ham SDR QRP Transceiver, 20K-220MHz RF Generator. 3.9"L x 3.5"W x 1.6H. 1 Lithium Polymer batteries required.

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. VFO for Ham SDR HAM QRP Transceiver? Used as a local oscillator on Homebrew radio receivers (such as superheterodyne, SDR, direct conversion and Homebrew QRP transceivers), a simple RF/clock generator for calibration reference or clock generation, a common 128x64 I2C OLED SSD1306 display and Si5351 module. Intermediate frequency (IF) offset (+ or -) is adjustable. The bar graph of the signal meter through the analogs input (ADC). I2C data transmission, only need 2 lines it can be connected to the display, with high stability and accuracy of frequency generation. Equipped with generator function mode. Initial frequency, end frequency, sweep-frequency-step can be set. 20 band presets (shortcuts) for BCB and HAM frequencies. RX/TX mode selector for Homebrew QRP transceivers. If you have any questions, please, we will reply and improve in time. Ham SDR HAM QRP Transceiver. This is a VFO (Variable Frequency Oscillator) project that can be used for DIY self-made devices such as superheterodyne receivers, DCR transceivers, SDR transceivers or Ham QRP transceivers. It also has bar graph indicators for signal strength (S-Meter) and 20 Band presets.

And can also be used as an RF/clock generator. 1 It has 10kHz to 220MHz working ranges. 2Intermediate frequency (IF) offset (+ or -) is adjustable.
