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.
10 steps to determining the best digital migration path.
When a company decides to purchase a radio station, the station's technical plant is often overlooked by the buyer.
New technology can be described as either emerging or breakthrough. IBOC is hardly breakthrough.
In the middle of May, the road to IBOC took a major detour. What has been an ongoing work in progress with a predictable slow and steady pace has been
WELL-FM's Western Electric transmitter, the first Picks Hits and the attendance trend at NAB.
When reception trouble is reported, it's not always easy to find the cause.
WIBW, Topeka, chose a digital exciter for its analog needs today and its digital growth tomorrow.
When buying a new transmitter, you will most likely be replacing an old unit or building a new site.
The PR&E ADX, IBOC at NAB1994 and radio listening habits.
WOR has encountered many positive results during its transition to IBOC. These tests were used to gather data on nighttime interference.
When STL transmitter and receiver products kept coming up short, we turned to the new, high-power STL-20C.
As public rejection of tall towers has increased, radio engineers have been paying more and more attention to AM antenna design requirements in an effort to develop shorter AM antennas that are as efficient as their taller brethren.
KKXS, Shingletown, CA, improves its signal with a new antenna. Read about it in this review.
As the FCC continues to delete mandatory measurements and checks from the Part 73 rules, some unintentional traps are opened for the unwary engineer.

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.
