WWV, WWVH, and WWVL may be shut down. Are there any alternatives?

GPS-based frequency standards @larsks answer rightly pointed at devices that use GPS to generate the 1-second pulsing. That's the correct way to go. Curiously, these modules only address the once-...

WWV, WWVH, and WWVL may be shut down. Are there any alternatives?

In No WWVB? No problem!, KB6NU points at two projects that show you how to build your own low-powered WWVB-replacement to keep your clocks in sync: μWWVB: A Tiny WWVB Station. This project uses an ...

WWV, WWVH, and WWVL may be shut down. Are there any alternatives?

Don't forget about CHU (and here is the official site) which is the Canadian equivalent to WWV. It's at lower power and it's not as well-located geographically (it's located near Ottawa), but it's ...

Are there any terrestrial timecode signals receivable in Boston Massachusetts?

WWVB propagation does vary in amplitude. And its BPSK phase modulation makes it a bit tricky to lock to. But if you narrow the bandwidth enough, signal is most always above the noise. Here's an ...

60kHz WWVB receiver help

One problem with breadboard construction involves the high-gain TRF signal chain @ 60 kHz...you get 60kHz feedback from breadboard back to loop antenna. It may help to put a low-gain amplifier at the ...

Mexican version of WWV?

No, there are no radio stations that broadcast time and/or accurate frequencies in Mexico. According to these webpages, here are no time or frequency stations anywhere in Central America. https://...

Are there any terrestrial timecode signals receivable in Boston Massachusetts?

Apart from the American time signal stations on shortwave. There is also CHU the Canadian time signal from Ottawa on 3.330 MHz, 7.850 MHz, and 14.670 MHz using USB mode.

Are there any terrestrial timecode signals receivable in Boston Massachusetts?

You should be able to pick up WWVB at 60 kHz, or WWV at 2.5, 5, 10, 15, and 20 MHz. Propagation should allow you to routinely receive at 60 kHz, 2.5 MHz, and 5 MHz most nights unless the ionosphere ...
