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!
