Product details
20K-220MHz Superheterodyne Receiver Software Defined Radio HAM QRP Transceiver RF Generator VFO Radio Debugger RX/TX mode selector for Homebrew QRP transceivers. It can be used as a local oscillator on Homebrew radio receivers (such as superheterodyne, software defined radio, direct conversion and Homebrew QRP transceivers). Intermediate frequency (IF) offset (+ or -) is adjustable. Tuning step of 1Hz, 10Hz, 1kHz, 5kHz, 10kHz and 1MHz. And also can be used as a common 128x64 I2C OLED SSD1306 display and Si5351 module. bar graph of signal meter through analogs input (ADC). 20 band presets (shortcuts) for BCB and HAM frequencies. 0.5PPM high precise Tcxo clock, frequency is more accurate. I2C data transmission, only need 2 lines it can be connected to display, with high stability and accuracy of frequency . Can be used as a simple /clock generator for calibration reference or clock . Equipped with generator function mode. It has 10kHz to 220MHz working ranges.
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 radio 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 /clock generator.

SDR Receiver
Item received was NOT a receiver at all! No manual, no instructions, no return information was provided. I will NEVER order anything from Walmart again!
