Description
# WSPR-beacon **[GitHub project page | WSPR-beacon](https://github.com/IgrikXD/WSPR-beacon)** A small hardware device for transmitting WSPR messages based on the SI5351 IC. The device has a built-in TCXO to eliminate SI5351 frequency drift, a built-in GPS module for operation with active GPS antennas, transmission time synchronization and automatic QTH locator calculation, and a simple amplifier based on a single BS170 transistor. PCB is made on based on SMD components and adapted for installation in an aluminum enclosure with dimensions 80 x 50 x 20 mm. ## Basic characteristics of the WSPR-beacon: **RF connectors:** SMA **Feed line:** 50 Ohm coaxial cable **GPS antenna type:** active, external **Maximum output power:** ~23 dBm **Supply voltage:** 5V, USB-B **Used PCB Material:** FR-4 **PCB thickness:** 1.6 mm **PCB copper weight:** 1 oz ## Resources: [A Little WSPR Beacon (Aren’t They All Little?) – Dave Richards AA7EE](https://aa7ee.wordpress.com/2023/02/26/a-little-wspr-beacon-arent-they-all-little/) [ESP WSPR – Simple and Inexpensive WSPR Transmitter - Ankara Telsiz ve Radyo Amatörleri Kulübü Derneği](https://antrak.org.tr/blog/esp-wspr-simple-and-inexpensive-wspr-transmitter/) [HarrydeBug/WSPR-transmitters: Arduino firmware for ZachTek WSPR transmitters.](https://github.com/HarrydeBug/WSPR-transmitters/tree/master) [K1FM-WSPR-TX - GitHub](https://github.com/adecarolis/K1FM-WSPR-TX) [QRP Labs QRSS/WSPR TX Kit](https://qrp-labs.com/images/ultimate3s/assembly_u3s_r3_lt.pdf) [WSPR beacon – Projets radio](https://hamprojects.wordpress.com/2019/06/02/wspr-beacon/) [WSPR - Signal Identification Wiki](https://www.sigidwiki.com/wiki/WSPR) ## Who helped me with the development of the project?
