WWV continuously broadcasts time signals at 2.5, 5, 10, 15, and 20 MHz, and WWVH does the same at 5, 10, and 15 MHz.
There are many uses for these radio stations. For example, I have a shortwave radio in my observatory and use the WWV voice time broadcasts on 2.5, 5, and 10 MHz to make sure my GPS clock is properly synchronized, and also use it to set my computer clocks accurately and well as my wristwatch.
WWV and WWVH are an important and reliable “low tech” backup to the Global Positioning System (GPS) satellite constellation which can be used to derive accurate times.
Well over 50 million devices use the 60 kHz signal provided by WWVB to allow them to maintain accurate time, and eliminating this particular service would be devastating. Whether or not shutting down WWVB is part of the proposed budget cuts remains to be seen.
These U.S. Government radio stations have been announcing accurate time since World War II. We must do all we can to ensure their continued operation.
