ATSC 3.0 Downconverters, Premium NextGen TV Shopping List
By Vicki Way Kipp
Supply-Driven Scarcity
The pandemic-related chip shortage and supply chain issues have actually increased the supply of high-end NextGen TVs manufacturers are producing. TV set manufacturers have prioritized high-profit margin products such as large NextGen TVs, given the scarcity of chips. The supply shortage is delaying the rollout of low-priced NextGen receivers.
Dolby NextGen Ad Campaign
Dolby is expected to launch a TV ad campaign called "Dolby's Sound Decisions," promoting NextGen audio features like dialogue enhancement and a consistent volume level. Dolby's ad titles include "Dialogue Drama" and "Sound Surprise."
CES NextGen logo
Manufacturers may put the official CES NextGen logo on their TVs if they meet ATSC 3.0 interoperability test specifications, but logo use is optional. www.cta.tech/Membership/Member-Groups/Video-Division/NEXTGEN-TV
Chipset
It's worth noting that most ATSC 3 receiver chips contain both ATSC 1.0 and ATSC 3.0 receivers.

Silicon Dust promotes the HDHomeRun HDFX-4K-DEV is promoted for "…development and tinkering if you want to do more than watch TV. Only useful for developers." I suspect that the Development edition could be useful for broadcast engineers, as well. Silicon Dust's counsel that the HDFX-4K-DEV is "Only useful for developers" actually heightens its appeal.

Outlook
If the ATSC 1.0 transition is any indication, NextGen consumer receivers should start to come down in price as soon as the pandemic-related chip shortage and supply chain issues are resolved.
National EAS Test Results
The large majority of the EAS Participants - radio and television stations, cable television systems, direct broadcast satellite (DBS), Satellite Digital Audio Radio Service (SDARS), digital audio broadcasting systems, and wireline video systems - reported successful receipt and retransmission of the nationwide test. The test thus demonstrated that the national EAS distribution architecture is largely effective as designed.
As anticipated, the test also shed light on issues with reception and retransmission of the alert. In summary:
• The test message reached 89.3% of the EAS Participants, an increase from 82.5% in the 2019 test.
• The overall retransmission success rate was 87.1%, which is an increase from 79.8% reported in 2019
• Test participants reported roughly half as many issues with receipt and retransmission as compared to 2019
• Radio broadcasters had a participation rate of 79.9%, down from 82.0% in 2019
• Television broadcasters' participation rate was 62.6%, down from 68.2% in 2019
• 1027 (5.5%) did not receive a transmission
• 389 (2.1%) had equipment issues
• 103 (0.6%) had configuration issues
• 78 (0.4%) had signal issues
• 53 (0.3%) had power issues
• 48 (0.3%) had antenna issues
• 31 (0.2%) had clock issues
• 26 (0.1%) had lightning issues
• 17 (0.1%) had "out of broadcast range" issues
• 7 (0.0%) had internet issues
• 1147 (6.2%) did not receive a transmission
• 565 (3.1%) had equipment issues
• 94 (0.5%) had configuration issues
• 64 (0.4%) had power issues
• 47 (0.3%) had clock issues
• 31 (0.2%) had signal issues
• 29 (0.2%) had antenna issues
• 29 (0.2%) had "out of broadcast range" issues
• 22 (0.1%) had lightning issues
• 18 (0.1%) had low power issues
• 13 (0.1%) had internet issues
• 4 (0.0%) had delivery issues
The Report's Conclusion: The 2021 nationwide EAS test demonstrated an improvement from 2019. Receipt and retransmission rates increased, while reported monitored source complications markedly decreased. As observed in 2019, the system would largely perform as designed, and it would reach the vast majority of the public, if activated without the availability of the Internet. The Bureau will continue to work with FEMA, EAS Participants, and other EAS stakeholders to improve the system and ensure that it remains effective and can transmit timely and accurate national alerts to the public when they are needed the most.
Amateur Radio News
Compiled by Tom Weeden, WJ9H
In what's billed as "A day of education to share ideas, experiences, knowledge and fellowship among Amateur Radio operators," the 23rd annual Ham Radio University is scheduled for Saturday, January 8th. Normally held in person in the Brookville, New York area, due to Covid complications, it will be held virtually for the second year. The 19 forums in this year's event include sessions on Grounding, Basics of HF (high-frequency) Operating, Satellite Operation, Contesting, HF Digital Modes, Software Defined Radios, and Raspberry Pi Apps for Ham Radio. As in past years, participation in HRU 2022 is free. An optional donation of $5 is suggested. Additional information and registration is online, at hamradiouniversity.org .
On December 24th, experimental station WI2XLQ was on the air on 486 kHz AM to commemorate the Christmas Eve 1906 transmission by Reginald Fessenden. Fessenden claimed one of the first voice and music transmissions over radio from Brant Rock, Massachusetts. (While some doubt Fessenden's Christmas Eve broadcast actually happened, the Ocean Liners Magazine description of the alleged broadcast can be found at ) oceanlinersmagazine.com .
Brian Justin, WA1ZMS, holds the experimental license for the commemorative station, which used a "homebrew" 1921-era MOPA (Master Oscillator Power Amplifier) exciter with Heising modulation, followed by a modern 500 watt linear amplifier. A video of reception of WI2XLQ on 12/24/2021 is at youtube.com .

To apply for a specialist certification, an individual must currently hold certification on the Broadcast Engineer, Senior Broadcast Engineer, Professional Broadcast Engineer or Broadcast Networking Engineer Certification level. Exams must be completed within three hours and consist of 50 multiple-choice questions (two points each) and one essay question (20 points maximum). Examinees are provided one essay question to answer. Exams are pass/fail, and a score of 84 is a passing grade.
Next Generation of CertPreview
In 2021, the Ennes Educational Foundation Trust allocated funds to the Certification Committee to develop a new CertPreview program. The committee contracted the firm of Stevens and Stevens to create this program. Development work is underway, with an expected release date of late 2022. A primary difference is that CertPreview will be Web-based. A major advantage to this is that updates to the sample test questions can be made in real-time, as technology advances. Watch for more information this year on the rollout of the new CertPreview format.
January Webinars
SNMP, Module 3: SNMP - What is it Good For? Absolutely Everything!
January 13, 2022 | 1 p.m. CT
Module 3 of the SNMP Series will explore the use of the Simple Network Management Protocol in broadcast facility control, with a focus on the benefits. We will look at how broadcasters are using SNMP to make their lives easier, and their facilities more robust and resilient. From the simple sharing of information to consolidate data and functions from multiple physical sites onto a single display, use of SNMP has expanded to include control of virtual audio switchers, automatic site handovers and other processes that can help engineers resolve technical issues quickly and maximize up-time!
