Docooler 20K-220MHz Superheterodyne Software Defined HAM QRP Transceiver RF Generator VFO Debugger

Please note this item ships from an international seller. Expected delivery is 10-15 days. This is a VFO (Variable Frequency Oscillator) project that can be used for DIY self-made devices such as superheterodyne receivers DCR transceivers software defined 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 RFclock generator. Features: It has 10kHz to 220MHz working ranges. 0.5PPM high precise Tcxo 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. Equipped with generator function mode. RXTX mode selector for Homebrew QRP transceivers. The bar graph of the signal meter through the analogs input (ADC). It can be used as a local oscillator on Homebrew receivers (such as superheterodyne software defined direct conversion and Homebrew QRP transceivers). Can be used as a simple RFclock generator for calibration reference or . And also can be used as a common 128x64 I2C OLED SSD1306 display and Si5351 module. I2C data transmission only need 2 lines it can be connected to the display with high stability and accuracy of frequency .
