The latest OTA update from Myriad RF is out and includes details on:
- The BATC Portsdown digital TV transmitter project now supports the LimeSDR USB, in addition to its earlier compatibility with the smaller LimeSDR Mini and all-in-one LimeNET Micro.
- Tech Minds’ Matthew Miller has posted a video walking through his first QSO through the QO-100 amateur radio transponder aboard the Es’Hail-2 satellite – using a LimeSDR Mini.
- Salil Tembe has published a build guide for a simple high-frequency (HF) upconverter designed for use with a LimeSDR Mini or other transmit-capable software defined radio.
- Lime Microsystems has published a video demo showcasing the CrowdCell open small-cell base station, built on LimeSDR technology, running the Amarisoft stack to create a fully-functional self-contained Long Term Evolution (LTE) cellular network.
- Those looking to get started running software defined radio projects on Linux have a new route into the hobby, courtesy of a community spin of Ubuntu Linux pre-loaded with SDR tools and drivers: DragonOS.
- Raspberry Pi owners, meanwhile, can now download an updated version of Luigi Freitas’ PiSDR distribution for their single-board computers.
- The SWLing Post has published a build guide from Bob Colegrove for a passive resonant transformer-coupled loop (PRTCL) antenna, built from basswood and copper wire.
- Elsewhere on SWLing Post is a pair of guides to recovering ferrite codes from old VGA cables and turning them into binocular ferrite cores for noise-cancelling passive loop (NCPL) antennas.
- Hackaday has brought to our attention a project from Alberto Gariassi which turns an off-the-shelf field-programmable gate array (FPGA) development board into a software-defined radio – of a sort.
- ARRL, the US national association for amateur radio, has reported on initial successes with remotely-administered amateur radio examinations under video supervision.
- Finally, a community member has succeeded in porting the gr-noaa blocks from older GNU Radio releases to GNU Radio 3.8 and higher, addressing a hole in the ecosystem brought about by breaking changes in the latest releases.
