Dear rec.aviation.soaring subscribers!

I would like to present you PDF slides of one DIY R&D project.
The slides are about open platform airborne proximity warning device.
It operates at ISM band radio but also capable to receive ADS-B reports at aviation frequency.
It is mainly targeted for our local soaring club use but can also attract pilots worldwide.

The presentation is downloadable at: https://github.com/lyusupov/Argus/ra...g_Dev ice.pdf

Hi Linar -- can the "TTGO T-Beam" board be used as a ground-based OGN receiver?

Thanks, John
