Quality of radio reception (Local or DX) received on Sony CFD-S350SILVER boombox is dependent on multitude of environmental factors, seasonal conditions, astronomical occurrences, principles of radio propagation, laws of physics, F.C.C. broadcasting regulations regarding broadcasting power transmissions and circumstances beyond your control. Reception changes based on time of day, atmospheric conditions, presence of sun spots, solar flares, solar winds, solar storms during daytime hours, movement of radio waves from one part of earth to another, close by ham radio operators, nearby power lines and electrical motors near home, proximity of appliances emitting RF interference to Sony CFD-S350 boombox, type of material home or room is made of, distance from broadcast tower(s) to home, presence of mountains, hills or skyscrapers in neighborhood, signal strength of broadcast station received and quality of Sony CFD-S350 boombox antennas and radio receiver. Radio reception varies by geographical location. It can’t be determined in abstract if tuner design of boombox is responsible for quality of radio reception customer experiences. Digitally tuned portable stereo is not inherently superior in radio reception compared to analog counterpart. Sony CFD-S350 boombox tuner’s sensitivity and selectivity performance with respect to weak signal and adjacent channel reception thrives or dives on quality, electrical design, thermal design and craftsmanship of tuning circuitry, variable frequency oscillator, signal processing, noise filters, micro controller unit, calibration of digital tuner and built-in system FM/AM antennas. Digitally tuned boombox radio merely provides convenience to listeners as they are able to store preset stations into memory. Customers instantly recall preferred radio stations and programs at touch of button on digital tuner. Nevertheless, digitally tuned boombox radio suffers less from station-drift than analog tuned boombox radio with large tuning knob. Accurate, clear and drift-free radio reception for Sony CFD-S350 boombox inevitably fluctuates. It is not possible to give definitive answer as to exact distance radio broadcast can be received at specific point of day or night. Only general range of broadcast reception is estimated in miles when determining if specific broadcast is capable of being received by Sony CFD-S350 boombox. FM radio signals are broadcast at higher altitude than AM signals. FM Band radio interference is caused from multipath reflections of radio waves off tall buildings or nearby mountains in neighborhood. Reception area of FM signals range between 40-100 miles. FM coverage is shorter than AM because FM signals travel in straight lines (line-of-sight) and have reduced interaction with earth’s ionosphere. FM monaural reception offers better sound quality compared to AM. FM mono signals are susceptible to less interference than AM radio broadcasts. FM stereo broadcasts provide high fidelity sound to target radio audience and shortest reception range in particular market on 87.5-108 MHz frequency spectrum. AM Band stations on 530-1710 kHz frequency band periodically reduce power at night as required by F.C.C. regulations or perform maintenance operations on transmitter adversely affect reception on Sony CFD-S350 boombox. Transmissions of AM radio broadcasts are longer than FM broadcasts. In daytime, AM Band radio broadcasts traveling via ground wave transmission reach listeners within several hundred mile radius. At night, AM Band signals roaming via sky wave travel hundreds or even thousands of miles away from intended radio market. DX reception of remote AM Band radio stations is possible after sunset because of AM broadcaster’s ability to bounce signals off outer reaches of earth’s atmosphere to Sony CFD-S350 boomboxes outside of intended radio market. AM DX reception is best during winter months and at lowest point of performance in summer. Sony CFD-S350 boombox’s internal ferrite bar antenna bolsters AM band reception of Clear Channel 50,000 Watt stations. FM band reception is enhanced on Sony CFD-S350 boombox by extending telescopic whip antenna to achieve full quieting results. An examination of various sources of radio interference is an important subject as it pertains to Sony CFD-S350 boombox radio’s day-to-day performance. Most sources of radio frequency interference come from entertainment devices within home emitting radio frequency waves. Radio interference is caused by phenomenon occurring outside home, in immediate surrounding area of home, deteriorating atmospheric conditions and/or interference from adjacent broadcast frequencies on FM band. Listeners experience interference from nearby electronic equipment in home from such items as computers, cordless telephones, microwave ovens, cellular telephones, televisions, stereo systems, compact disc players, electric power tools, and everyday household appliances. RF interference is caused from lighting equipment, metal objects and nearby broadcasting equipment. A competing broadcast station adjacent to station being listened to bleeds into tuned station to degrade reception opportunities as well. Moving Sony CFD-S350 boombox closer to window and away from electronic devices transmitting harmful RF interference dramatically improves FM/AM reception. Medium Wave Band coverage is expanded upon indoors with external omnidirectional passive antenna. For example, Terk AM Advantage Indoor Antenna makes use of electromagnetic procedure known as inductive coupling to improve AM Band reception by placing antenna in close proximity to Sony CFD-S350 boombox. A third party FM antenna, such as C. Crane FM Reflect Dipole Antenna is attached via alligator clips to whip antenna on Sony CFD-S350 boombox for improved FM Band reception indoors. Sony CFD-S350 Portable Stereo’s Digital FM Stereo/AM Dual Band Tuner is of exceptional high-performance. I have not experienced noise, static or distortion with Sony CFD-S350 boombox in radio market I live in. Sony CFD-S350 boombox’s FM Band Tuner receives the following stations in New York City Metropolitan Area: 88.3, 88.9, 89.9, 91.5, 92.3, 95.5, 97.1, 100.3, 101.1, 101.9, 102.7, 103.5, 104.3, 105.1, 105.9, 106.7, 107.5 MHz.
