A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously.SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet. WebSDR.org was created by PA3FWM, Pieter-Tjerk de Boer ...SWR stands for "standing wave ratio" and is a measure that can be used to tune an antenna for a particular frequency. The closer the SWR is to 1:1 at the designed antenna frequency, the better the antenna will receive (and transmit). In his video Adam shows how he measures the SWR of an ADS-B antenna which he has built and is selling. His ...Jul 4, 2023 · A Tale of Two SDR Rigs: FlexRadio 6400M vs. RTL-SDR. Let’s take a closer look at the significant differences between a high-end SDR, like the FlexRadio 6400M, and the budget-friendly SDR dongle, like the RTL-SDR. It’s important to understand the vast disparity in performance and capabilities between these two SDR options. FlexRadio 6400M:SDR++ is an open source, cross platform, C++ based GUI general receiver program for various SDRs including the RTL-SDR. Since it's alpha release in mid 2020, it has undergone huge amount of development, and is quickly becoming the main program of choice for many users due to it's efficiency, cross platform and multi-SDR hardware support and increasing feature set. And with an easy GUI very ...

RTL-SDR is a very cheap ~$30 USB dongle that can be used as a computer based radio scanner for receiving live radio signals in your area (no internet required). Depending on the particular model it could receive frequencies from 500 kHz up to 1.75 GHz. Most software for the RTL-SDR is also community developed, and provided free of charge.Measure and analyze your SDR-generated pipeline. According to The Bridge Group, the average SDR generates $3 million of new pipeline per year, with a typical range of $1.8M to $4.7M. There is a wide variance based on your average deal size, company maturity and target market. To understand how much pipeline your SDRs are sourcing, Sally ...
