This tracking transmitter consists of four distinct subassemblies; a free-running multivibrator, a transmit switch, an audio-tone generator, and an FM transmitter. The multivibrator (which produces a pulse width with a pulse separation of 1500 ms) is built around Ql and Q2. The multivibrator output is coupled through R5 to the base of Q3, whose emitter feeds Q4,
After that I went to college and interned with an talk and loved all aspects of radio. ... Akey: Clearly the most important trend in the oadcast and greater media industry is an attempt to determine effective content delivery platforms; whether
DTS's HD Radio technology includes a time-diverse backup channel in all AM and modes. HD Radio technology takes advantage of time diversity by delaying the backup (analog) .... While this structure works quite well in the lab, getting a GPS rec
He found the anomaly while performing an equipment performance measurement test on a new . So like any good engineer, he trotted out an meter and spectrum analyzer. He was able to conclude that some indeterminate intermodulation ...
Radio magazine The schedule delivers in-depth sessions on diversified technology such as combiners, AM antenna proofing, IP audio, oadcast plant design and even an boot camp of sorts. “The Broadcast Engineering Conference highlights a

The NAB agrees with one provision related to cross-service siting: allowing the 60 dBμ contour of an cross-service translator to be contained within the larger of a 25-mile radius from the AM's site or the AM's daytime 2 mV/m contour
UniverseThis is because most systems from the transmitter to the antenna are frequency-specific. This concept may seem foreign to some radio oadcasters. Generally speaking, today's solid-state , filtering, transmission line and antennas ar
BandMaxson reports that he discovered the strange phenomenon while performing an equipment performance measurement of a new . “FCC Rule 47 ... Maxson says it remains to be seen if the phenomenon occurs at lower levels. All levels at
