My VHF OpenWebRX+ receiver was working flawlessly for months, and in the last few weeks I’ve been thinking of building something similar for the UHF band, given that there is a lot of satellite activity nowadays. The turnstile antenna Adding an LNA and the cavity filter V1 Replacing the antenna...

A few weeks ago, I stumbled upon a cool project in which YO3GND uses the Flipper Zero’s internal CC1101 radio as an APRS UHF transmitter. The C1101 radio can transmit and receive from 300 to ~1 GHz and is the core of the Flipper Zero’s Sub-GHz radio. I thought it...

A while ago, I built and made available a dual-band VHF/UHF OpenWebRX+ Internet SDR receiver, https://sdr.nico.ninja. Time passed, and things changed. I replaced both RTL-SDR.com v3 SDR receivers with my old, unused HackRF One. I also decided to cover just the VHF ham radio band, from 144 to 148 MHz...

A note for the readers: This project is fully documented (from a technical perspective) in reynico/radioberry-setup Shortly after finishing the Vertex VX1700 RadioBerry build, my dad showed up at the workshop with a Yaesu FT-80C he had stored away for years. The radio was fully working - nothing wrong with...

A note for the readers: This project is fully documented (from a technical perspective) in reynico/radioberry-setup Mid last year, my father introduced me to RadioBerry, an open-source FPGA-based Raspberry Pi Hat platform for HF SDR transceivers (0 to 30 MHz). The board uses an AD9866 modem chip and an Intel...
