Hello all,
This is very nice! Thanks for the efforts. DCF39 appears at 85 dB SNR,
which is about as strong as expected :-) You already detected some
stations proving the system is working.
Time to run some good old QRSS-60? Mike?
I guess that grabber is one of those few that are available 24/7/365,
which is very valuable!
BTW i need to 'repair' my OPDS-32 instance. Somethig isn't working...

In a most enjoyable collaboration with Bernd DF9RB, Tom DK1IS and
Florian DL1FLO, we have launched a new 137 kHz grabber in Amberg,
JN59VK:
https://lf.u01.de/
It is located on the same quiet site as our VLF grabber:
https://vlf.u01.de/
The LF receiver is a Perseus with a GPS-locked 80 MHz clock, connected
to the first wideband SpecLab instance. The filtered audio is then
passed on to three different narrowband instances, as well as a WSPR
decoder and an opds Opera-32 correlation detector. We can also save
FFT-export files for the EbNaut decoder if transmissions are announced
beforehand.
Have fun!
