SI5351 WSPR Transmitter, FOR TCXO GPS Automatic QTH Positioning 23DBm RF Communication Test Equipment (WSPR BEACON beacon)

• SI5351 WSPR TRANSMITTER WITH TCXO: Professional RF communication test equipment eliminates frequency for DRIFT through integrated Temperature Compensated Oscillator, delivers stable 23dBm maximum output power for reliable weak signal propagation reporting in shortwave QRP operations.
• GPS AUTOMATIC QTH POSITIONING SYSTEM: Built-in GPS module works with active external antenna to provide transmission time synchronization and automatic grid location calculation, eliminating manual coordinate input for amateur radio operators and field testing applications.
• PLUG-AND-PLAY CONFIGURATION VIA SERIAL PORT: Configure call sign, grid coordinates, and operating frequency through simple serial port interface without external software or complex coding requirements, streamlining setup for WSPR beacon operations and RF analysis tasks.
• PROFESSIONAL BUFFER DESIGN WITH 74ACT244 CHIP: Enhanced signal integrity through dedicated buffer circuitry connected to standard RF connector, compatible with 50Ω coaxial cable for professional-grade RF measurement and data acquisition in business industrial testing environments.
• COMPLETE TESTING PACKAGE READY TO DEPLOY: 50x20x63mm ABS housing includes GPS antenna, Type-C power cable for USB-5V operation, for portable shortwave propagation analysis and RF communication system evaluation in laboratory or field conditions.

Features: A small WSPR message transmission hardware device based on the SI5351 chip. This device incorporates a TCXO to eliminate frequency for DRIFT of the SI5351 and a built-in GPS module for use with an active GPS antenna. It features transmission time synchronization and automatic QTH positioning calculation, and employs a buffer based on the 74ACT244 chip. After configuring the call sign, grid (GPS is used by default), and frequency through the serial port, it can be used without the need for external software or code.
