JUNSHUNTONG HF VFO for Ham SDR QRP Features
-
【HF VFO /RF Generator 】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.
-
【Adjustable】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
-

About JUNSHUNTONG HF VFO For Ham SDR QRP
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. Features: 1) 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. 2)Intermediate frequency (IF) offset (+ or -) is adjustable. 3)20 band presets (shortcuts) for BCB and HAM frequencies. Equipped with generator function mode. 4)RX/TX mode selector for Homebrew QRP transceivers. 5)The bar graph of the signal meter through the analogs input (ADC). It can be 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. 6)I2C data transmission, only need 2 lines it can be connected to the display, with high stability and accuracy of frequency generation.
