Radio has always had a connection with listeners and the public. In a way it''s the original social media outlet. And radio stations still connect to their audiences through public appearances.

Like all technology, radio remote equipment has moved forward with the times. Establishing a direct RF link is nearly a forgotten practice in larger markets. Even ISDN, once touted as the future of all telephony, has come and gone as a common connection option with many telephone companies dropping the service.

But we are a connected society. It''s rare to be anywhere in the U.S. without some kind of Internet access. IP connectivity has gained importance as a practical means of audio contribution delivery.

In this column we try to present several products in an equal setting so you can see an apples-to-apples comparison of features and specifications. We have done that here as usual, but we have noticed that each manufacturer has its own view of important features. Like any data product, while one unit may shine in a specific situation where another one just gets by, changing the variables can just as quickly shift the application curve to another product.
