In the UK, we’re fortunate to have several of these synchronisation stations, based on the Atomic Clock at Greenwich. One of the most widely used in terms of analogue signals is the beacon which broadcasts on 10.0 MHz using Carrier Wave, (CW) and which has been broadcasting for I don’t know how many years.
There are several digital signals as well but they’re all broadcast at UHF as far as I know. But I guess the thinking behind this change is that an ever-increasing number of appliances and services now synchronise directly via the atomic clocks, or via GPS. In the latter case, they must rely on the Internet being available. I’m not saying I agree with the change. There should have been a much longer time frame on this, in order to allow manufacturers to develop products which synchronise using different methods. GPS is only really reliable outdoors, which out of necessity precludes a lot of consumer items from the list of possibilities. The Internet, on the other hand, would necessitate the presence of broadband or similar. That in itself is fraud with difficulties. However, I can see why the government is trying to do this. It’s obviously going to be quite a money saver and that, I am sorry to say, is a governing factor the world over. I am sure this will happen to us at some point as well. I can only hope it’s a few years off. On 25 Aug 2018, at 17:38, Dane Trethowan <grtd...@internode.on.net> wrote: So what will you do? I wonder just how many list members have time pieces that rely on this time synchronisation service? I don’t think the good folks in Europe or Australia rely on WWVB but certainly its big in the US, the digital signal is broadcast on 60KHZ. If WWV and WWVH fall silent as well then this will bring some difficulties to me too as I have quite a few time pieces here that rely on manual synchronisation with a time signal and the only accurate time signal we have left now as far as I know is WWV/WWVH on the Shortwave bands - 2.5, 5, 10, 15, 20 and 25MHZ -. > https://hackaday.com/2018/08/20/what-will-you-do-if-wwvb-goes-silent/ > <https://hackaday.com/2018/08/20/what-will-you-do-if-wwvb-goes-silent/> ======================================== My compliments and kindest regards Gordon Smith: <gor...@mac-access.net> Accessibility & Information Technology Support Specialist..
