Antenna currents and field strength
Sometimes we lose sight of the relationship between current in an antenna and the resulting field strength value.
NAB2004 in review
The NAB Convention review covers various aspects of the convention, from the sessions to the exhibit floor to the talk in the aisles.
Safety first
It may seem that a typical broadcast facility doesn't have all the safety concerns of a construction site or a manufacturing facility, but accidents happen.
Relaxed LPFM interference rules
Given industry opposition to relaxation of the third-adjacent channel protection standard, the matter may not see the light of day in the foreseeable future.
Getting the most from tower inspections
Tower inspection expenses are small compared to the financial consequences of not spending the money on one. However, make sure that this is actually
Concerning combiners
Until the advent of FM, combiners were rarely required. After FM was introduced, the need for a method of feeding two or more FM frequencies into a single

Field Report: Harris Intraplex STL Plus
WQSX-FM chose the Intraplex for its IBOC upgrade and provides this review.
Changes in tower standards
Sometime this year the Telecommunications Industries Association (TIA) will release the most comprehensive revision to the tower standards since 1996.
The IBOC FM waveform
The IBOC system for FM as developed by Ibiquity is a fascinating engineering feat.
The search continues
In the summer of 2003 we began our search to find the oldest transmitter in daily use. We received some submissions directly from stations, while others
The digital age has arrived
One day we'll look back and remember when the digital age of radio began.
Shaping radio today and tomorrow
A 44-year old console, a cassette deck with hopes of greatness and a look at consumer music spending habits.
The data dilemma
IBOC has been officially launched, but what do we do with the data capacity?
New transport methods
When considering methods to move information from one point to another, it is interesting to reflect on how our needs have changed over just the past 20 years.
Shaping radio today and tomorrow
A look at the oldest transmitter in daily use and a radio-training course from days gone by.
Frequency coordination for BAS
The FCC's newest prior coordination procedures for the Broadcast Auxiliary Service (BAS) took effect in October.
The birth of a radio station
A station owner is motivated to build a top-notch facility serving a dynamic market.
Contemplating the Future
After our review back to 1994, we look ahead to 2004 and investigate what the future of radio might be.
Shaping radio today and tomorrow
A look back at the Studio A820, DAB progress in 1994 and a continued increase in Internet media usage.
IBOC antennas
Despite the hiatus in nighttime operation for AM IBOC, antenna research is continuing in an effort to comply with the FCC's existing requirements of two antennas for FM IBOC, and develop a system using one antenna that will satisfy the FCC's requirements.
4 Times Square Antenna Project
The Durst Organization, the real estate management company of The Condé Nast Building (4 Times Square) in New York City has undertaken the massive project of tripling the height of the tower high atop the building, coming into its own as a premier transmission facility.
The value of the subcarrier
If you want to know who is investing money into FM subcarriers, look no further than the computer giant Microsoft.
A busy month
So much happened last month, so there is lots of ground to cover.
Staying neutral
Because of inductive and capacitive circuits, it is often easy for undesired and usually unwanted oscillations to be generated in an amplifier stage. Neutralization is important to keep these systems at maximum efficiency.
