Update regarding the NPR Labs IBOC Power Calculator
Now that the FCC has acted on the NPR/iBiquity IBOC Power Proposal, the NPRLabs IBOC Power Calculator, originally provided as a courtesy to the industry to estimate allowable digital ERP for preliminary planning purposes, has been superseded.
Although the FCC ruling adopts the NPR-recommended power increase formula, the IBOC Power Calculator itself was based on a snapshot of the FCC database from late 2009, and is not to be relied upon for filing purposes.
Licensees may now prepare to file for voluntary digital facility upgrades, which should be based on accurate, current studies prepared by a qualified engineer, to determine their station's permissible digital ERP.
Please feel free to contact NPR Labs for more information on preparing digital ERP studies via
Comments and questions on retiring the power calculator should be directed to
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.

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.
