Easy-SDR. This project is about creation of affordable and easy-to-manufacture prototypes of PCBs which are used to expand the capabilities of existing low-cost SDR receivers based on RTL2832U chip.

WSPR-beacon. A compact hardware device for transmitting WSPR messages based on the SI5351 clock generator, using GPS for transmission timing synchronization and automatic QTH locator calculation.

rpitx-ui. RF transmitter toolkit for Raspberry Pi with improved UI and enhanced core functionality, built with CMake.

rpitx-coax-pcb. 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.

Antenna-analyzer. Creating a public prototype of the "SWR-mouse" antenna analyzer PCB compatible with the G403 (Gainta Industries) ready-made case.

SDR-Exp. Some experiments with SDR equipment (GNU Radio, SoapySDR, etc.) that are used by me for self-study of SDR and DSP technology.

rpitx-expansion-board. 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!
