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.
WELL-FM's Western Electric transmitter, the first Picks Hits and the attendance trend at NAB.
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
When buying a new transmitter, you will most likely be replacing an old unit or building a new site.
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.
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.
1994: The EIA and NRSC review seven DAR systems at NASA's Lewis Research Center in Cleveland. Also, On the air in 1931 and a llok at listener loyalty.
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.
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.
