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
WQSX-FM chose the Intraplex for its IBOC upgrade and provides this review.
Sometime this year the Telecommunications Industries Association (TIA) will release the most comprehensive revision to the tower standards since 1996.
The IBOC system for FM as developed by Ibiquity is a fascinating engineering feat.
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
One day we'll look back and remember when the digital age of radio began.
IBOC has been officially launched, but what do we do with the data capacity?
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.
A 44-year old console, a cassette deck with hopes of greatness and a look at consumer music spending habits.
After our review back to 1994, we look ahead to 2004 and investigate what the future of radio might be.
A look at the oldest transmitter in daily use and a radio-training course from days gone by.
The FCC's newest prior coordination procedures for the Broadcast Auxiliary Service (BAS) took effect in October.
A station owner is motivated to build a top-notch facility serving a dynamic market.
A look back at the Studio A820, DAB progress in 1994 and a continued increase in Internet media usage.
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.
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.
If you want to know who is investing money into FM subcarriers, look no further than the computer giant Microsoft.
So much happened last month, so there is lots of ground to cover.
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.
With the FM implementation of IBOC, standard broadcast stations will need to deal with a number of technical problems related to making IBOC work with RF propagation issues.
Although there are many software options for evaluating FM stations, there are few software packages to evaluate AM stations. AM-Pro is perhaps the newest package available, and it is proving to be one of the best.
An early Gates transmitter and a look back at AM directional rules.
A radio transmitter is a collection of stages. How these stages function determines the operational capability of each transmitter.
Local telephone companies no longer support analog dedicated circuits. The PCAU gets around the limitation, as this review describes.
