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?

I don't see it here in Denmark either.

Just checked my four Austrons (2 on the "Master", 2 on the "Slave" signal.

All four had lost tracking, all four sat at acquire at present, and
have been for long enough to suggest they can't lock on.

Hopefully it is a fault, or antenna work, I'll give the Austrons
another prod later if they don't wake up. Last I heard, eLoran
was good until at least the end of 2017 from Anthorn.

I now have all four with green tracking lights, so looks good to go
