The NAB Fastroad project funded the report, which includes a proposal for industry-standard energy efficiency rating for transmitters.
FM translator service, since its inception in the very early 1970s, has been subjected to several major technical overhauls.
Lighting surge protectors
Understanding the mechanics of your RF program delivery system, and maintaining a keen grasp of the associated fade margin can go a long way to diagnosing the rare, but ultimately problematic impact path failure can have.
The master antenna system mounted on the Empire State Building suffered a major lower bay failure on Oct. 18, 2010.
One good working definition of the Smith chart is that it is simply a graphical calculator for normalized impedance and associated RF parameters.
Broadband motorized switch
Fixed directional couplers
Satellite radio images on TV
8dB FM IBOC hybrid injector
MACXLine rigid transmission line
The bottom line is that without maintenance, transmission line will ultimately fail. The good news is that with regular and periodic inspections, the likelihood of unplanned failures is greatly reduced.
Coaxial transfer switch
Voltage sampling unit
RF power sensor
Increasing the IBOC digital sidebands from -20dBc to -10dBc presents more challenges for broadcasters wanting to transmit from one antenna.
In June 2009, Mississippi Public Broadcasting culminated a multiyear effort and inaugurated two-channel HD Radio transmission to all eight of its Class C FM analog stations.
Doug Irwin predicts that Oslo is well on its way to becoming one of those classic pieces of equipment that engineers will talk about for years to come.
One of the hallmark missions of the FCC is to promote the use of the radio spectrum; the corollary is that the Commission ends up being a traffic cop to eliminate interference, more accurately stated as reducing interference.
While there are similarities between various grounding methodologies, asking 10 engineers for their opinions will probably return a minimum of eight different and valid recommendations.
WKSU had a major decision to make: Either add 5,000 square feet onto the broadcast center building or complete the installation of IBOC technology at its non-IBOC stations and further enhance the network with the implementation of multicast channel and program-associated data capabilities for each station.
The upcoming generation of radio engineers will encounter a new ease of measurement as a fact of the Commission's new directional antenna proof rules.
It appears Harris did some serious homework on this transmitter. The controller is like nothing I have ever seen before.
The development of the operating impedance bridge by Delta Electronics about 40 years ago made antenna impedance measurements not only much easier to perform, but more accurate.
