Advanced IBOC Coverage and Compatibility Study (Final Report) Available
This report adds sections dealing with compatibility (impairment to analog main FM channel reception from same-station IBOC transmissions) and a means for estimating increases in IBOC coverage at elevated digital powers.
 
NPR Labs Online Viewing Applications for Public Radio and Television
The NPR Labs Public Television Online Viewing Application and the NPR Labs Public FM Radio Online Viewing Application comprise a set of tools that let users dynamically explore mapping and demographic data for PTFP-qualified FM and TV transmitters.
The tools are now freely available your interaction, and are intended for anyone affiliated with a PTFP-qualified FM and/or TV transmitter. Please see the abstracts introducing these tools and the scope of work in these PFTP studies.
 
20100301: REVISED NPR Labs PAD Applications for iBiquity v4.x and later Importer software
NPR Labs has learned that the PAD applications provided free-of-charge to NPR Members are incompatible with iBiquity's version 4.x and later Importer Software. NPR Labs has been working to revise the software, and is developing the replacement using the PADSDK provided through iBiquity Digital Corporation.
The alpha version has recreated the software as a Windows service with 'plug-in' components to operate the desired PAD stream, flexible scheduling to allow different services to push PAD to the same network port at different times.

Digital Radio Coverage and Interference Analysis Study Now Available
NPR Labs has completed their DRCIA project - a monumental 18-month study projecting the consequences of interference between HD Radio and station analog broadcast signals, as well as HD Radio’s overall success in meeting coverage expectations and needs. Visit http://www.nprlabs.org/research/drcia to download the final report.

Research - IBOC Interference Maps

Based on methodology developed in NPR Labs' Digital Radio Coverage and Interference Analysis Project (DRCIA), we have prepared detailed maps showing analog FM stereo coverage and interference under three conditions: Analog-only interference, IBOC interference at one percent power, and IBOC interference at ten percent power.

A brief technical explanation of the methodology is available here.
A tabulation of all population counts and historgrams summarizing the impacts are available here.
