The LimeSDR Mini development board is a hardware platform for developing and prototyping high-performance and logic-intensive digital and RF designs that use Altera’s MAX 10 FPGA and Lime Microsystems’ LMS7002M RF transceiver. Simply put, the LimeSDR Mini is a smaller, less expensive version of the original LimeSDR. However, it still packs a punch – at its […] Read more

Wipe out noise and interference before it gets into your receiver with a 60 dB null! Eliminate all types of noise — severe power line noise from arcing transformers and insulators, fluorescent lamps, light dimmers, touch controlled lamps, computers, TV birdies, lightning crashes from distant thunderstorms, electric drills, motors, industrial processes. It’s more effective than […] Read more

“The NanoVNA does many things. Two of which are testing coax cables for loss and length. Jim W6LG shows how to do both in this first video about the NanoVNA. In a subsequent video, Jim will show how the NanoVNA can be used to check antennas for resonance, impedance and reactance. The software that Jim […] Read more

The sensitivity of a radio receiver is a key operational parameter and it is limited by the system noise. The sensitivity of a radio receiver determines the weakest signals that can be successfully receiver. Whether it is an audio signal for which the listening quality deteriorates as the signal falls into the noise, or a […] Read more
