Subject: freq shift of DCF42
DR OM,
Since 17-7-2004 I have noticed an irregular frequency shift on
the pilot carrier of the german DGPS transmitter (DCF42),
nominally 122.5 KHz. In the past, it was always coherent
with other accurate LF-sources.
The shift is about .74 Hz +/- .01 Hz downward.
It was verified by Markus Vester, DF6NM.
Although it could be intentional, I suspect a fault at the transmitting
site, with possible consequences to the system 's accuracy.
It looks pesistent since yesterday, 22-7.
I have tried contacting the site through internet, without success
up to now.
Does anybody know more, or how to address the site?
