Research & Development

circa 1989 & 2016

History:


     Back in the '80s, one of my favorite devices from childhood was a Radio Shack Multi-frequency Short & Long Wave analog manual radio. It was huge and had several degrees of fine-tuning so that you could discover weak but clear signals/voices. So when I would listen to the radio, I could mentally travel to China, CCCP, BBC, France, or listen to Morris Code and other non-descriptive languages on VHF, UHF, to enrich my understanding. 


    Since computers were not readily available or affordable in the '80s, I would have to memorize the frequencies and use manual tuning, so you could hope to achieve the same station or broadcast station(s) from the following evening.

   Above is my R&D POC prototype, pocket Windows computer, Software-defined radio (SDR), custom algorithm, software modifications, a broad Spectrum antenna, a Blue tooth antenna, a WiFi detector, blah, blah, blah...

KISS:


     When I was in High School-1988, I heard students whose Families or friends got raided by the Police. So because these students seemed so traumatized by the Police, I came up with a KISS (Keep It Simple Stupid) Popo-Scanner.


    In 1988 my POC (proof of concept) used a Radio Shack analog spectrum radio to measure the strength of specific radio frequencies (not decipher them). In turn, I would let them know if 'Law enforcement was in your location or approach. :) 


    Hack:

    Since Law enforcement used radios (at specific frequencies), as the Police were physically getting closer to the house, the spectrum radio-meter would receive the increase in radio "signal strength" and at a predetermined signal strength, it would cause the piezoelectric alarm to signal. This alarm would let them know that the "Popo" or Government was in your area..., giving them a chance to at least finish using the toilet... lol :o

Reboot  

   

     Years later, I remembered my High School analog device and decided to "try" it again, but this time with "modern digital" technology.  The result (below) was a Pocket Windows computer using FOSS Software-defined radio (SDR), custom algorithm, soft/hardware modifications, a broad Spectrum antenna, a Blue-tooth antenna, a WiFi detector, blah, blah, blah, wink, wink, nudge, nudge, say no more, say no more... Lol


Curious...


    My modern digital PoPo Scanner iteration/version, did NOT rely on any high tech "hacking" or complex signal deciphering, as it was solely based on a passive

'detection algorithm'

which was derived from old B2 Bomber stealth-tech.
