![]() Because many hosts, DJs and announcers speak quickly and cover complex topics, you might not land on a station that fits your comfort level at first. You get to hear language as it’s naturally spoken - not filtered or altered to be easier for language learners. There are few better ways to immerse yourself in the goings-on of countries and cultures you might not be able to visit in person.Īs a language-learning tool, the Spanish radio stations are great for helping you fine-tune your listening skills and hear authentic pronunciation in context. Historically, radios could only tell you what was going on nearby, but now radio broadcasts can be transmitted over the internet to anywhere. Radio stations are a great way to tune in to the freshest currents in sports, journalism, entertainment and much, much more. If you’re learning Spanish and you’re sick of leafing through books or squinting to read subtitles, you might find language learning with Spanish radio stations more refreshing. Why not use some of it in your language learning journey? The radio is a fantastic tool for mastering a new language, no matter where you are around the world. Listener comments and reception reports may be emailed to: wwv nist.There’s a lot of noise saturating the world’s airwaves. As an experimental broadcast, the 25 MHz signal may be interrupted or suspended without notice.Īntenna: half-wave vertical dipole. The broadcast consists of the normal WWV signal heard on all other WWV frequencies, at the same level of accuracy. WWV has resumed broadcasting on 25 MHz on an experimental basis. The modulation level is 50 percent for the steady tones, 50 percent for the BCD time code, 100 percent for the second pulses and the minute and hour markers, and 75 percent for the voice announcements. The signals broadcast by WWV use double sideband amplitude modulation. This sloping skirt functions as the lower half of the radiating system and also guys the antenna. The bottom half of each antenna consists of nine quarter-wavelength wires that connect to the center of the tower and slope downwards to the ground at a 45 degree angle. The top half of each antenna is a quarter-wavelength radiating element. The shortest tower, for 20 MHz, is about 7.5 m tall. The tallest tower, for 2.5 MHz, is about 60 m tall. Each antenna is mounted on a tower that is approximately one half-wavelength tall. Each antenna is connected to a single transmitter using a rigid coaxial line, and the site is designed so that no two coaxial lines cross. There are antennas at the station site for each frequency. The WWV antennas are half-wave vertical antennas that radiate omnidirectional patterns. The variety of frequencies makes it likely that at least one frequency will be usable at all times. Although each frequency carries the same information, multiple frequencies are used because the quality of HF reception depends on many factors such as location, time of year, time of day, the frequency being used, and atmospheric and ionospheric propagation conditions. Each frequency is broadcast from a separate transmitter. The station radiates 10 000 W on 5 MHz, 10 MHz, and 15 MHz and 2500 W on 2.5 MHz and 20 MHz. WWV operates in the high frequency (HF) portion of the radio spectrum. The broadcast information includes time announcements, standard time intervals, standard frequencies, UT1 time corrections, a BCD time code, and geophysical alerts. WWV is located near Fort Collins, Colorado, about 100 kilometers north of Denver. NIST radio station WWV broadcasts time and frequency information 24 hours per day, 7 days per week to millions of listeners worldwide. ![]()
