SELF MADE EQUIPMENT: This is a VFO(Variable Frequency Oscillator) project, which can be used for self made equipment, such as superheterodyne receiver, DCR, SDR or Ham QRP transceiver 2. BAR GRAPH INDICATOR: Also has a bar graph indicator for signal strength(S Meter) and 20 Band presets, and can also be used as an RF or clock generator 3. 10KHZ TO 220MHZ WORKING RANGE: Working range is 10kHz to 220MHz, can be used with for Pro Mini. Use general 128x64 I2C for OLED display and Si5351 module 4. 2 WIRES TO CONNECT: Support I2C data transmission, only need 2 wires to connect the display or Si5351, very convenient 5. HIGH STABILITY AND ACCURACY: Frequency generation has high stability and accuracy, simple but very effective Specification: Item Type: SDR QRP HF Transceiver Working Range: 10kHz to 220MHz Tuning Step Size: 1Hz, 10Hz, 1kHz, 5kHz, 10kHz and 1MHz Intermediate Frequency (IF) :455KHz 20 Band Presets: BCB and HAM frequencies (shortcuts) Mode: Generator function mode RX OR TX Mode Selector: For Homebrew QRP transceiver Bar graph of signal meter via analog input (ADC) Uses: 1. Used as a local oscillator on for Homebrew radio receivers (such as superheterodyne, SDR, direct conversion and for Homebrew QRP transceivers) 2. Used as a simple RF/clock generator for calibration reference or clock generation 3. Can be used with for Pro Mini Universal 128x64 I2C forOLEDdisplay and Si5351 module Transmission: I2C data transmission, only need 2 wires to connect the display or Si5351 Battery Information: 3.7V lithium battery, 600mAh Package List: 1 x SDR QRP HF Transceiver 1 x USB Data Cable 1 x Connector Note: You need to read the parameters carefully before making a purchase. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ 1) We accept Alipay, West Union, TT.All major credit cards are accepted through secure payment processor ESCROW. _x000D_ _x000D_ _x000D_ 2) Payment must be made within 3 days of order. _x000D_ _x000D_ _x000D_ 3) If you can't checkout immediately after auction close, please wait for a few minutes and retry Payments must be completed within 3 days. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ About shipping _x000D_ _x000D_ _x000D_ 1.
