A look back at the Philips DCC, an increase in high-speed Internet access, and 10 Years of Radio looks back at the IBOC tests of 1994.
Why buy new when the existing equipment still works fine? Keep some of that vintage equipment running right.
Ignorance of the rules is not a valid excuse when an inspector comes calling. Here are some of the frequently overlooked rules.

Now that the FCC has accepted IBOC, we will see even more improvements as sites are updated with digital exciters and solid-state transmitters. With all of these advances in technology, don't overlook what can become the weak link: the method used to get the audio from one location to another.
When problems of abnormal VSWR occur, they generally result from mechanical or electrical damage due to the transmission line or antenna, and frequently to heavy ice formation on the antenna.
Modern equipment is stable and reliable, but some things should be checked on a regular basis.
In October the Commission announced procedures that allow AM and FM stations to immediately begin interim IBOC digital transmissions on a voluntary basis.
A look inside the radio chipset that promises improved reception without the costs of digital transmission conversion.
With the FCC's reduced logging requirements, there is no excuse for a directional array not to have adequately written maintenance logs.

A robust transmission system is one that provides superior signal and audio quality, and provides this superior product even in adverse conditions.
There are several factors to keep in mind when it's time to select a new transmitter.
The fundamentals of the folded unipole have not changed much since 1952, but experience has provided several improvements as well as some weaknesses.
The use of somebody else's tower can be attractive, but before rushing into a contract with an existing tower owner, consider all the problems that can occur.
When vertical real estate is at a premium, diplexing AM stations may offer an cost-efficient alternative.
with proper engineering precautions, towers can survive intense lightning attacks.
This single-tube FM transmitter is reviewed.
Adequate grounding means different things to different engineers.
It would not be correct to say that IBOC was on everybody's lips at NAB, but there was considerable interest in it.
Ranging from spotless high-rise suites to dirt road shacks, the transmitter site represents a station's final, vital link to the listener.
Some transmitter manufacturers have already announced the availability of FM IBOC transmitting equipment, and offered actual equipment at the NAB show. FM IBOC requires considerably more equipment than the AM version, and it is more expensive.
The Commission is on the verge of approving the Ibiquity standard, but serious questions still exist as to the value of the system to broadcasters and whether a full-time AM system will ever work.
To all but those who must maintain them, studio-to-transmitter links are a silent and sometimes forgotten step in the transmission chain.
Many engineers anxiously awaited the release of the National Radio Systems Committee's AM IBOC Report, in hopes that the report would reveal good news about AM IBOC.
