Antenna & SDR Projects

Do-it-yourself projects for radio amateurs, shortwave listeners and backyard astronomers: VHF Slim Jim and multi-band wire antennas, software defined radio, a pan-adapter for the Yaesu FT-950, a DX crystal set, a PC power supply converted to 13.8 V, and deep-sky astrophotography. Each project page is a build log with design notes, measurements and photos.

The project write-ups were first published by amateur station AC8GY around 2010 and 2011 and are kept here as an archive. This site is not run by AC8GY; see About. New project articles will be added over time.
