CubeSatSim, the AMSAT CubeSat Simulator

Expansion board for Raspberry PI allowing to use coaxial SMA output instead of direct wire connection to GPIO to connect radio equipment when working with the rpitx package.

Rpitx, but has better pifmrds

RF transmitter for Raspberry Pi with improved UI functionality.

Transmitter with Raspberry PI over OpenHPSDR Protocol 1

Expansion board for Raspberry Pi 4 Model B that eliminates the need for a direct wired connection of radio equipment to GPIO when working with rpitx or rpitx-ui packages. Now, you can use coaxial SMA output, switchable filters, and built-in LNA on one board!

This repository will have the code to use rtl_sdr dongle vir reception and rpitx as transmitter

Short message radio packet protocol, able to transmit ~90 ASCII-UTF8 characters per minute between raspberry pi pwm + sdr receiver.

A simple AM/FM/SSB modulator flowgraph for rpitx in GRC

Simple program using rpitx to control ceiling fans
