Sound, Mind and Body Assault Weapons Detection Projects

Found this interesting RTK GPS system module that is accurate down to 1cm, yeah, 1cm is what is claimed.  This video is the source:  https://www.youtube.com/watch?v=_a1ixhYJe60 Figured I'd share.  https://www.sparkfun.com/products/15136 Reference comparison oscillators: https://en.wikipedia.org/wiki/Crystal_oven#Comparison_with_other_frequency_standards Updates Since May : Hackaday: rtl-sdr-seven-years-later article with comments detailing applications Hackaday :  tuning-into-atomic-radio-quantum-technique-unlocks-laser-based-radio-reception/ Neat system... though I'd like to work on a cost effective DIY wideband laser interferometer to more easily perform a mHz to ̶E̶̶H̶̶z̶̶ PHz spectrum analysis. Still... this system seems interesting.  The below post corrupted me when I posted a comment, along with watching a video by  The thought emporium  to make a similar interferometer about the same time and a video by Physics Girl a few weeks late...

Spectrum Analysis Upgrade -   I've been busy with travel though a little pickin of worthy free items as well as great deals on electronics and RF engineering related systems with the latest acquisition opening up the capabilities of spectrum analysis up to 110GHz potentially and 18.5GHz with the detectors I have already.  Still lots of reading and some writing also regarding DEW's, electronics and RF engineering. I've been trying to find information regarding the operation of the 1038-N10, -NS20 and -NS201 devices.  I've been able to find info on the mainframes and H/V systems. Started a Facebook group regarding: https://www.facebook.com/groups/698747963909529/ ...as well as updated the Tekwiki wiki which didn't have much at all initially: http://w140.com/tekwiki/wiki/Pacific_Measurements_1038 Found a  free Brother MFC9970CDW Color Laserjet that the engineering office lady said needs the fuser replaced and otherwise works great. The printout noted the laser is a...

 Fluke 8840A Startup - Why does the mV & V readings not stabilize to zero with the terminals not shorted and when tested later in the mV range when shorted still +/- 00.0020 when there are no ERROR during calibration?

https://www.anritsu.com/en-GB/test-measurement/video-gallery/anritsu-signal-hunters-episode-1 Signal Hunters Episode 1 Taking spectrum analysis to new heights! The MS2760A is the latest release in the Ultra-portable family of USB driven instruments - it can perform spectrum measurements from 9kHz to 110GHz in the industries smallest and lightest form factor. To test the versatility of this new class of instrumentation Signal Hunters’ Luke and Becca decided to see if they could find a hidden microwave signal by mounting the new MS2760A on a commercial drone – watch the video to see the results and see how the Anritsu Spectrum Master MS2760A ultraportable spectrum analyzer with best in class sweep speed, dynamic range, and continuous frequency coverage up to 110 GHz performs. Reads like is about a ~$60K investment to own... however, leasing is the way to get around the high expense. 

Here is a brief refresher on electrophysiology   by body part  and  not so much  cell, cell cluster and/or tissues details. https://en.wikipedia.org/wiki/Electrophysiology#Electrographic_modalities_by_body_part Now consider this  electro-osmosis effect  demonstrated in the video below  with a potential and current measured.   Then consider later observations regarding the measurements. That is a low current and ultimately wattage capability  to cause effect from what I observe.  Interesting eh?

Here is a great reference that I will use when I get to updating the RTL-SDR Procedure with new SDR and application information... especially regarding GRC... for when installing GRC on Windows OS computers: http://www.gcndevelopment.com/gnuradio/downloads.htm In regards to ELF-ULF-VLF work (basically in the sound card range) with or without mixing to upconvert or downconvert... here are some software application references I've found really helpful: http://www.radio.imradioha.org/pc_based_test_gear.htm I've been using Visual Analyzer which seems like a great all in one application. This application was recommended and isn't freeware... though may be work the investment: http://www.daqarta.com/ Reference regarding what could be the systems to consider detecting even if not in the disclosed frequency ranges: http://defaakto.com/2018/11/24/mysterious-health-attacks-against-u-s-canadian-diplomatic-embassy-staff-cuba-china-an-open-source-intelligence-study-by-de-faakto/
