		A radio clock is a clock that is synchronized by a time code bit stream transmitted by a radio transmitter connected to a time standard such as an atomic clock.
		Such a clock may be synchronized to the time sent by a single transmitter, such as many national or regional time transmitters, or may use multiple transmitters, like the Global Positioning System.
		Radio clocks synchronized to terrestrial time signals can usually achieve an accuracy of around 1 millisecond relative to the time standard, generally limited by uncertainties and variability in radio propagation.

		A radio clock is a clock that is synchronized by a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
		Radio clocks synchronized to terrestrial time signals can usually achieve an accuracy of around 1 millisecond relative to the time standard, generally limited by uncertainties and variability in radio propagation[?].
		Loran-C time signals may also be used for radio clock synchronization, by augmenting their highly accurate frequency transmissions with external measurements of the offsets of LORAN navigation signals against time standards.

	Information about WWVB Radio Controlled Clocks
		A radio controlled clock has a radio inside, which receives a signal that comes from a place where an atomic clock is located.
		Not all clocks have this feature, so you might have to select another time zone to make your clock display the correct time when DST is in effect.
		The clock might not have been properly aligned at the factory, or it might have been jostled during shipment, causing the hands to move.

	Simple Radio Clock for PC's
		Due to delays in the propogation of the radio signal, it's processing by the receiver board and the latency of the operating system the time decoded by the receiver will be slightly slow of actual UTC.
		The basics of the calibration procedure is to determine the average offset of the radio receiver, and use the time1 fudge factor in ntp.conf to bring the receiver as close as possible to the real time.
		The easiest way of determining the offset of the radio receivers time is to run it against a reference clock that does not suffer from these problems.

	Build a WWVB Radio Controlled Nixie Clock
		A common example of the Radio Clock movement is designed and manufactured by Quartex Inc, and rebranded for their distributor: Atomix.
		If your Nixie Clock design is based on the customary 1pps signal from a crystal or 60hz line frequency, you can use the WWVB radio receiver hack described here.
		Overall clock error is less than 100ms from the WWVB clock transmission.

	Clock Radio - Gizmodo
		This is a clock radio with an iPod dock, so we plugged our iPod nano into it and took it into the official Gizmodo bedroom for a hands-on sleep test.
		From the outside it seems that this clock radio just has a CD slot and OLED display, and I can't figure out if this concept radio will have everything controlled by remote control or fl magic because the website is just filled with artsy-fartsy talk.
		The ezWake alarm clock radio looks fairly conventional until you take a close look at its 22-key remote control, giving you plenty of say-so over what happens from a distance with the diminutive $99 radio.

	Radio Controlled Analog Clock
		This atomic clock regulates the WWVB radio transmitter located in Fort Collins, Colorado, where the exact time signal is continuously broadcast throughout the United States at 60 kHz to take advantage of stable long wave radio paths found in that frequency range.
		Radio waves at these low frequencies use the earth and the ionosphere as a wave-guide and follow the curvature of the earth for long distances.
		Within five minutes the clock will either receive the WWVB signal and set itself to the exact time, or it will determine that the signal is not receivable at its current location and time of day.

		The radio thumbwheels are on the side of the case and this is AM only.The case is intact but there are a few dings and marks about it, but stills looks good!
		The clock runs great but the radio has a loud buzz even tho it does pick up stations, so it needs the filter capacitors replaced.The plastic cover of the clock face has stress marks to the bottom corner but is very clear still.The case needs a polish job and has no scratches!

	Oregon Scientific RM 313 P Clock Radio - Review - Alarming...Which is the Whole Point
		Fortunately, however, the clock is also mains powered, so this isn’t necessarily something you’ll need to do often, but for those with hand problems, this is going to be really difficult to open when required.
		Thanks to the radio signal, there is no need to adjust the clock for daylight savings time, as the clock does it all for you.
		Unfortunately, hitting the snooze button, which is a large button on the top of the clock, is a lot easier than hitting the alarm off button, which is one of the rubbery buttons on the front of the clock and, if that’s the button you press, 8 minutes later it sounds again.

		A radio controlled clock is accurate to within a second and never needs to be adjusted.
		Radio controlled clocks are commonly referred to as "atomic clocks," but that isn’t technically true.
		A radio controlled clock contains a relatively simple antenna and radio, which receives an atomic clock synchronization signal that is transmitted from a place where the atomic clock is located.

	Reference Clock Drivers
		Radio and modem clocks by convention have addresses in the form 127.127.
		The local clock driver also supports an external synchronization source such as a high resolution counter disciplined by a GPS receiver, for example.
		When more than one clock driver is supported, it is often the case that each shows small systematic offset differences relative to the rest.

	Which alarm clock is best? - By Dan Crane - Slate Magazine
		Chris Bailey, curator of the American Clock and Watch Museum in Bristol, Conn., dates the earliest alarm clocks in America to grandfather clocks that colonists brought from England.
		The built-in radio sounds as tinny as a drive-in speaker, and the alarm tone is harsh and grating.
		Many new alarm clocks boast the "smart set" feature, meaning the clock comes magically preset to the correct time—all you have to do is adjust it for your time zone.

	Playlist: Review: iHome Audio iH5
		After switching to radio mode and choosing a band via the buttons in the control area, you use the Set dial to choose the station.
		Configuring the iH5’s clock is easy enough: First you set the time zone by pressing the Time Zone button on the back of the unit until the Time Zone indicator on the LCD blinks, then turning the Set dial to the appropriate time zone, then pressing the Time Zone Button again.
		Finally, like any good clock radio, the iH5 includes a snooze button that gives you an extra 9 minutes of sleep in the morning, and a sleep feature that lets you listen to the radio or your iPod for 15, 30, 60, 90, or 120 minutes as you go to sleep at night.

	Radio Controlled Clock
		Really all I would have needed to do for the project was to build the radio receiver, plot its output on a chart recorder, and show that I could manually decode the time signal.
		But when the clock had decoded a whole minute's worth of radio signals, the clock would automatically switch to the correct time.
		Finally, be look at this excellent MSF Nixie Clock project by Steve Smith, who built from my basic design with a Maplin MSF receiver module and modified the display driver to use nixies.

	iHome iH5 Clock Radio for iPod Review - Mediacentric
		Among the booty Santa left this year was the iHome iH5 Clock Radio.
		It’s a bit on the big side for a clock radio (9.2″ wide x 5.5″ deep x 2.7″ high (without the iPod)), but I suspect that part of that allows for enough resonance to make it sound good.
		You can select from Radio, Buzzer and iPod for the alarm, and you can also use any of them with a sleep feature that is settable from 15 to 120 minutes.

	iHome iH5 Docking Stereo Clock Radio \| iLounge iPod Accessory Reviews
		The left and center of the clock’s screen show the time, while the right side uses icons and words to indicate status: an alarm clock icon shows the alarm’s on, while an iPod icon or the words “radio” or” buzzer” show which audio source the iH5 will play to wake you up.
		Given both our experiences with clock radios and with most sub-$100 iPod speaker systems, the biggest surprise about the iH5 is that it actually sounds pretty good.
		There are no preset radio features, but I suppose thats ok since you dont get any with most basic alarm clocks anyway (and I bought it to use it with my ipod anyway).
