0 Milliwatt Si5351A WSPR Beacon by NT7S 18 April 2016 It’s fun to experiment with propagation by seeing how far you can get a signal to travel with a transmitter in the milliwatt range (this is known colloquially as QRPp).

The Arduino uses the GPS module borrowed from NERD-1 for accurate time and then controls the output of the AD9850 DDS to generate the WSPR signal. Before anyone panics I know at the moment I only hold a Foundation Amateur Licence so the construction of homebrew transmitters isn't allowed.

Arduino AD9850 WSPR - pa3hfncom
Simple WSPR Transmitter You can use this data to transmit WSPR very simply. Putting this data into an array allows for easy recall in a sequenced manner. Here, I add the data into an array as you would expect to find in a C program. This is for Arduino v1, but is very universal.
Si5351_WSPR// Simple WSPR beacon for Arduino Uno
I have recently been experimenting with an low power amateur radio beacon kit that helps monitor and study HF radio wave propagation. The beacon is a low power transmitter that sends out a small digital packet that tells anyone who receives and decodes it: who sent it …

Modes : BPSK ,QPSK, RTTY, Hellschreiber, CW, WSPR. Tranmission on 3 bands alternatively. Synchronization by real time clock. LCD 420 display. SWR meter. The beacon is based on an arduino nano, it drives an AD9850 module by hardware serial communication (SPI). HF multimode beacon v1 (english version)

A Classie WSPR Transceiver - Computer/Electronics Workbench
WSPR beacon with Arduino . Hello, today i published the code for an beacon controller based on the popular arduino board. The code calculates the whole WSPR message and generates the 2 minute sine tone sequence. The software is synconized with an DCF77 timecode receiver. The tone sequence can drive the mic input of an transceiver or like i use
