The projects
Software and experiments around radio, SDR and navigation - from DAB+ and the HackRF One to centimetre-level positioning.
Projects
Qt-DAB Classic
A DAB+/DAB receiver for the HackRF One SDR: a fork of Jan van Katwijk's Qt-DAB with a compact "Classic" UI, EPG browser, timer, recording and emergency warning (EWF) - plus optimised signal processing.
dabtx
A DAB+ transmitter for the HackRF One: the full chain from PC audio through HE-AAC encoding and DAB+ superframe to COFDM modulation and IQ output. Up to 47 channels, including amateur bands (70 cm to 6 cm).
Note: transmit only within the legally permitted scope, i.e. on the amateur bands cleared for it.
smartphone-rtk
Centimetre-level positioning with a smartphone: an Android app injects RTCM3 correction data straight into the phone's internal GNSS chip via mock location - plus a complete NTRIP base-station stack for Debian/Raspberry Pi.
ATS Mini (firmware)
Firmware for the SI4732 pocket receiver (ESP32-S3): a small all-band receiver for FM, medium/long/shortwave and SSB - here as my own further-developed variant.
