Re: [time-nuts] Anthorn eLoran
Dave that may have been me. Yes there is other timing data on the signal. Thats what helps the receiver do a better job of understanding frequency and time. The old austrons and such do not process the bits. But if I had to guess its easy enough to actually get them out to experiment with.

Didn’t someone say a while back, that there appeared to be "other data" present on the transmission, but didn't know what it was, or used for... Or did I imagine it.? Maybe that's why they keep it going? 73. Dave G0WBX.

Re: [time-nuts] Anthorn eLoran
Its been quite the interesting read. I agree with the behavior of an antenna issue. They should just use a larger penny. That tends to work for a bit of time. I suspect the reason to keep it going though is to test eloran's time dissemination. The other sites are not needed for this purpose. In the US there is only one site and they fake out a second site with a delay so that the austrons and other receivers are happy. And it works. When the sites up its great to see the receivers all locked. No navigation though. However there have been some comments made by pretty smart people that I actually may believe that even with 1 site its possible to navigate. Please don't throw stones. But given the quality of a local Rb references today might it be possible? The new eLoran gives about a 10 X and more frequency/time accuracy. OK I am in very dangerous waters here. I hope I don't run onto the shoals. Humor intended. Reagrds Paul WB8TSL On Wed, May 10, 2017 at 4:22 PM, Alan Melia wrote: > Hi Peter > Ah that sounds more like it.

Re: [time-nuts] Anthorn eLoran
Hi Peter Ah that sounds more like it. Aerial maintenaance shuts down the whole site these dats including MSF. There is really no reason for them to keep it running but I think Trinity House are paying the bill. It cannot be used for nav without Lessay and the output from Sylt, So I muse that they are keeping it powered up because the equipment is quite old now (1990s vintage, the unused kit destined for Loop Head in Ireland) and if the leave it off for any length of time it just wont start again :-)) We all know that syndrome ! I dont know if this is correct but I got the feeling it was not running anything like full power??

[time-nuts] Anthorn eLoran
Is anybody monitoring eLoran from Anthorn? I'm less than 100 miles from the transmitter but an FS700 has been unable to find the signal for several days. Last time this happened though it turned out to be a local antenna problem so I didn't want to cry wolf until I found time to take a closer look. I'm now monitoring the signal with an LF receiver and spectrum display using a different antenna and the usual 100KHz signal is missing. I am seeing a slowly drifting signal between 103 and 104 Khz that does look similar to a Loran signal but am not set up on this receiver to do more than just observe it so can't be sure just what it is. It might that there's a fault or the system is down for antenna maintenance, there's no alerts on either these days as there is for MSF, or perhaps it's something longer term. Anyone know what the score is?
