    TWiRT Ep. 736 - AM Band Signal & Noise Study with John Kean & Dave Hershberger

    John Kean, Dave Hershberger, and Tom King recently set out to take measurements of RF noise levels on various roadway types from open interstate highways to city streets, to determine how the noise would affect AM broadcast reception. These environments reflect the current habits of AM radio listening, which is primarily in vehicles. In addition to RF noise level, RF signal levels were measured for three AM stations operating on frequencies in the low, middle and high ends of the AM broadcast band. These measurements provide a better understanding of how AM radio reception is affected by RF signal strength and noise in a range of roadway environments from rural to dense urban environments. On this episode of TWiRT, John Kean and Dave Hershberger join us to describe the testing methodology and the results and conclusions we can infer from them. Show notes: * NRSC-R102: Measurement of AM Band RF Noise Levels and Station Signal Attenuation * SDRplay RSPdx-R2 Wideband Full-Featured 14-bit SDR Covering 1kHz to 2GHz * Test Plan for Measurement of Multipath Distortion Parameters for AM SFNs Guests Dave Hershberger - Senior Scientist (retired) at Continental ElectronicsJohn C.

    TWiRT 732 - Broadcasters Need Today's Technology with Shaun Dolan and Rob Bertrand

    Today we're diving into a critical topic: the evolution from solo engineering efforts to collaborative support models in broadcasting. Just as a one-person band can only play so many instruments at once, a single engineer can't tackle every technical challenge alone. By banding together and working in groups outside traditional broadcast companies, we can support one another, foster career growth, and achieve a healthier work-life balance. Our guests Rob Bertrand and Shaun Dolan aim to do just that at Inrush Broadcast Services,, a 14-person broadcast technology service provider Show notes: * Inrush Broadcast Services is a consulting engineering firm serving the radio industry and adjacent media fields. * Shaun mentioned PagerDuty, a web platform designed to coordinate working teams and their efficient response to customers’ needs. * Shaun likes CoScreen, a multi-user screen sharing platform that makes collaboration truly efficient. * Rob is delighted with the Scout Pro 3 Ethernet cable tester and identifier from Klein Tools. Kirk loves it, too.

    TWiRT Ep. 726 - Moving Eight Radio Stations on Maui with Russell Laferty

    Akamai Broadcasting bought six radio stations (2 AM & 4 FM) plus a number of translators on Maui. Russell Laferty has been building new facilities, and your TWiRT host, Kirk Harnack, is helping with the final wiring and configurations. In addition to a new rack room and (so far) one studio, Russell is moving several studio-transmitter link (STL) systems and installing new ones. One highlight of the work has been improvements to two tower sites on Mt. Haleakala. We visit the upper site at close to 10,000 feet above sea level where Russell gives us a video tour of the building. Plus, learn how a defective Ethernet switch earned Kirk a trip to this transmitter site above the clouds. Show notes: Mt.
