I have also been running a #SuperSID. This is a #VLF receiver intended to detect Sudden Ionospheric Disturbances (SIDs) - typically from solar x-ray bursts. I've definitely picked up a couple but I recently replaced the monitor PC with a #RaspberryPI because Windows was too unreliable.
It has also forced me to clean up electrical noise from the house (typically dimmer switches).
An interesting side project was an EMI detector, which my son used as a ghost detector at Halloween

#VLF/#LF/#MF spectrum waterfall recorded for 5 hours overnight with #lightning in the area. Unfortunately the time is incorrect but I started this around midnight, a few hours later a storm system came through. Used an #RTL-SDR and a modified MLA-30 active loop antenna in the attic.

The solid line around 0.060 (60 kHz) is #WWVH. All the stuff on the right pat 0.50 (500 kHz) is the AM broadcast band.

There's harmonic/image of #WWV in there somewhere, probably due to a cheap setup but worth more experimentation to clean up, particularly needs better AM broadcast filtering (it's not supposed to show up). The signal path is <ActiveLoop>--<Power Injector>--<AM Band Filter>--<Upconverter - Ham It Up Nano>--<RTL-SDRv3>

#GQRX #SDR

Back in 2015 I made an #AR installation for the world heritage #rockcarving site in #Tanumshede, so I found it very interesting to see similar tech used to teach visitors about the workings of the #Grimeton #VLF #Radio Station.

It's a world heritage site on account of being the last operational long range mechanical radio transmitter, its design pre-dating vacuum tubes! It transmits #morsecode using a big spinning alternator wheel to generate a 17.2kHz signal which can reach New York and beyond

On December 24th 0700 UTC Grimeton SAQ in Sweden will send a Christmas Message #CW on 17.2 kHz.

Hobbies in recent yrs have included #homebrewing and #modelrailroading. This past year I've been into #radioastronomy & am a member of the Soc of Amateur Radio Astronomy.
So far I've been experimenting with #ELF - detecting whistlers from thunderstorms. As you can imagine, living in the S. Plains of the US are a good source!

I've also been operating a #SuperSID (Solar Ionosphere Disturbance) #VLF receiver but WinPC was unreliable so replacing with a #raspi. I'll post my progress & results!
