SI5351 WSPR Transmitter With TCXO And GPS Automatic QTH Positioning 23dBm For Tests Measurement Tools Accessory USB-5V

 

Features: 

A small WSPR message transmission hardware device based on the SI5351 chip.

This device incorporates a TCXO to eliminate frequency 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.
