[Lowfer] Early morning VLF

Hello Mike,

Nice to see 7 MSK signals in your spectrogram. What was the bin width (or
noise bandwidth or integration time) for the spectrogram?

My view of 15-40Khz this morning had the normal trio of NAA,NLK, and NLM.
Also seen was NWC AUS, NPM HI, and TFK/NRK Iceland. An unknown signal at
31.2.  I had a medium MSK signal at 40.0, but as I was checking the online
databases, the signal faded/ended. The database says that should have been
JJY Japan.

The screen capture is here;
