Revitalize AM

WDCD towers looking back toward the transmitter building

WDCD towers looking back toward the transmitter building

This is a series of blog posts on the all digital HD radio tests performed by iBiquity.  It is also a good study on how to revitalize the AM broadcast band with technical suggestions and programming ideas.

Part I: Discusses the all digital HD radio test on WBCN.  One test on a favorable subject does not success make

Part II: Discusses the history of AM broadcasting, regulations and technical developments/setbacks

Part III: Discusses some solutions to the above problems and notes that good programming and hard work is also necessary for success.

Part IV: An example of a successful, stand alone AM station in the Northeast.

All digital AM IBOC is more trouble that it is worth, it excludes small operators that cannot afford the upgrades or licensing, it creates interference and degrades audio quality.

There are better ideas including improved receiver technology, carrier frequency synchronization, wider daytime audio bandwidth and cutting away some dead wood.

...radio was discovered, and not invented, and that these frequencies and principles were always in existence long before man was aware of them. Therefore, no one owns them. They are there as free as sunlight, which is a higher frequency form of the same energy.
