LimeSDR is an open source, apps-enabled software-defined radio (SDR) platform that can be used to support just about any type of wireless communication standard; it can transmit and receive UMTS, LTE, GSM, LoRa, Bluetooth, Zigbee, RFID, and Digital Broadcasting, to name but a few.

The LimeSDR platform is comprised of a family of boards that range from a cost optimised 1×1 SISO board and a highly affordable 2×2 MIMO solution — both with USB3.0 interface — up to

OTA: AMSAT-F QO-100 Transmissions, SDR Added to RSGB Syllabus, New limeSNA, and More

The second AMSAT-F Recontre Radiomateur Spatiale was a special one, for an out-of-this-world reason: its lectures were transmitted to a global audience using a LimeSDR Mini and the Es’hail-2 (QO-100) satellite. Evariste Courjaud explained the transmission chain in an interview published this week on the Lime Micro community hub:…

Popular software package SDR-Console is set to get transmit support on the LimeSDR range, from version 3.0.4 onwards – once beta testing is complete. The new feature of SDR-Console v3.0.4 was teased by Jason Fairfax on Twitter late last month. “Calling CQ SSB on 144.300 MHz from IO81rk,” he…
