Live From Everywhere? The American Radio DJ In An On-Demand World (1A)<\/a><\/h3>\n

iHeartMedia owns and operates 858 broadcast radio stations, serving more than 150 markets throughout the U.S. The company reaches over a quarter billion monthly listeners ?in America.<\/p>\n

In January, news hit that iHeartMedia was reassessing its ability to adapt to the modern music industry. The company said that it plans to make \u201csignificant investments \u2026 in technology and artificial intelligence.\u201d<\/p>\n

However, its on-air DJs were caught off guard when they found out that the company\u2019s restructuring plan didn\u2019t include them.<\/p>\n

Streaming platforms has ushered in the digital age of music where each person make their own playlists. What does that mean for the future of the on-air DJ in the United States?<\/p><\/blockquote>\n

A comprehensive lab comparison between multiple software defined radios (RTL-SDR.com)<\/a><\/h3>\n

Librespace, who are the people behind the open hardware\/source\u00a0SatNOGS<\/a>\u00a0satellite ground station project have recently released a\u00a0comprehensive paper (pdf) that compares multiple software defined radios<\/a>\u00a0available on the market in a realistic laboratory based signal environment. The testing was performed by\u00a0Alexandru Csete (@csete<\/a>) who is the programmer behind GQRX and Gpredict and Sheila Christiansen (@astro_sheila<\/a>) who is a\u00a0Space Systems Engineer at Alexandru’s company AC Satcom. Their goal was to evaluate multiple SDRs for use in SatNOGS ground stations and other satellite receiving applications.<\/p>\n

The SDRs tested include the RTL-SDR Blog V3, Airspy Mini, SDRplay RSPduo, LimeSDR Mini, BladeRF 2.0 Micro, Ettus USRP B210 and the PlutoSDR. In their tests they measure the noise figure, dynamic range, RX\/TX spectral purity, TX power output and transmitter modulation error ratio of each SDR in various satellite bands from VHF to C-band.<\/p>\n

The paper is an excellent read, however the results are summarized below. In terms of noise figure, the SDRplay RSPduo with it’s built in LNA performed the best, with all other SDRs apart from the LimeSDR being similar. The LimeSDR had the worst noise figure by a large margin.[…<\/a>]<\/p><\/blockquote>\n

Radios that Never Were (N9EWO)<\/a><\/h3>\n

Shortwave: A Modern Internet Radio Player for Linux (It’s Floss)<\/a><\/h3>\n

Brief: Shortwave is a modern looking open source Internet Radio player for Linux desktop. We take a quick look at it after its recent stable release.<\/p>\n

Shortwave is an interesting open-source radio player that offers a good-looking user interface along with a great experience listening to the Internet stations. It utilizes a community-powered database for the Internet stations it lists.<\/p>\n

Shortwave is actually a successor of the popular radio app for Linux, Gradio. Its developer Felix joined GNOME and discontinued Gradio to create Shortwave from scratch in Rust programming language. If you were using Gradio as your preferred Internet radio station player, you can import the library as well.<\/p>\n

Recently, Shortwave released its first stable version and seems to push new updates after that as well.[…<\/a>]<\/p><\/blockquote>\n
