KFS WebSDR is the site near Half Moon Bay that does the receiving for all voice to skull and electronic harassment for police officers and was put into commission by Fresno Police Chief Jerry Dyer. He runs their WebSDR and signs into the chat as “Chief Dyer”. He uses it along with almost every police department in the US to create and harass “Targeted Individuals”.
They also use the Tiger Mountain ARC outside of Seattle for beaming microwave down into the city and South Seattle via a series of relays. This Microwave can burn people and it does NOT have to be setup in your neighborhood.
His second in command was arrested and sent to Federal Prison on Heroin and Marijuana distribution charges and his nephew Damon Dyer was once arrested in Clovis, CA on Oxycontin and Cocaine distribution charges.
It is a miniature HAARP and can hear people from Hawaii to the Caribbean. It uses a series of transponders to broadcast to people and keep track of them through a frequency database.
Technical Details of the system:
The KFS WebSDR HF radio server system is located near the mouth of Lobitos Creek on the Pacific coast, six miles south of Half Moon Bay, California, USA. This RF quiet location, on a 150 foot cliff overlooking the Pacific Ocean, is in maidenhead grid square CM87tj02; the geographic coordinates are 37° 23′ 6” North, 122° 24′ 45” West. You can easily locate the site using Google Maps or Google Earth by searching for “KFS WebSDR”.
The individual band receivers are FiFi SDR receivers with internal sound card chips, mounted in a custom rack mount chassis (thanks to KO6AQ). The 160 meter receiver is preceeded by a bandpass filter and a KD9SV Products SV-160 160 Meter Preamp, modified for rack mount, to compensate for the 3-30 MHz antenna response. All but one of the WebSDR receivers are fed from the Omni antenna, a TCI Model 530 Log-Periodic. The receiver for the 40ph band is switched, on a schedule, between the usual Omni and the SE Sector antenna, a TCI Model 527B Log-Periodic. The other two TCI 532 LP antennas (NW Sector and NE Sector) are not in use by the KFS WebSDR at this time. See below for more antenna details.
The server computer uses an ASUS Z170 motherboard with an Intel i5-7400 CPU in an ARK rack mount case with 8 GB of RAM, and an ADATA SP580 120 GB solid state drive. Three Startech PEXUSB3S44V 4-port USB cards are installed; they can connect up to 12 receivers. Version 9 of the Debian Linux operating system provides file system support. The Internet service provider is Coastside.net in Half Moon Bay. WebSDR server software was written and is maintained by Dr. Pieter-Tjerk de Boer, PA3FWM. Pieter maintains a list of active WebSDR servers and a FAQ page.

KFS Antenna Details:
There are four TCI receive-only HF antennas at the KFS site. The antennas feed lines entering the building are connected to a house RF distribution system that provides signals to all co-located HF tenants. Five Redifon MCU100 Antenna Multi-coupler units feed the second-floor tenants including the WebSDR and KiwiSDR receivers. Pictures of the antennas, courtesy of Hal, KK6HY, are here. Each antenna has a friendly name – Omni, NW Sector, SW Sector, or SE Sector – as decribed below:
“Omni” is a TCI 530 Short and Medium Range Log-Periodic Antenna (Model 530-4-02). Its dimensions are 217 feet long by 217 feet wide. It is supported by a single aluminum tower 92 feet high. The frequency coverage is 3 to 30 MHz. The pattern is omnidirectional with circular, horizontal, polarization. The nominal gain is 6 dBi.
“NW Sector” is a TCI 532 Medium Range Log Periodic Antenna (Model 532-4-02). Its dimensions are 330 feet long by 410 feet wide. It is supported by a single aluminum tower 149 feet high. The frequency coverage is 3 to 30 MHz, horizontally polarized, nominal 12 dBi gain, 13 dB F/B ratio. The take-off angle varies from 20 degrees at 30 MHz to 37 degrees at 3 MHz. A beamwidth of 55 degrees, at a bearing of 278 degrees true provides coverage from 251 to 306 degrees; this includes Japan, Indonesia, Western Australia, Hawaii, and the Western Pacific Ocean.
“SW Sector” is a TCI 532 Medium Range Log Periodic Antenna (Model 532-4-02). Its dimensions are 330 feet long by 410 feet wide. It is supported by a single aluminum tower 149 feet high. The frequency coverage is 3 to 30 MHz, horizontally polarized, nominal 12 dBi gain, 11 dB F/B ratio. The take-off angle varies from 20 degrees at 30 MHz to 37 degrees at 3 MHz. A beamwidth of 55 degrees at a bearing of 222 degrees true provides coverage from 195 to 250 degrees; this includes Hawaii, Eastern Australia, New Zealand, and the South Pacific Ocean.
“SE Sector” is a TCI 527B Super High Gain Log-Periodic Antenna (Model 527B-8-02). Its dimensions are 357 feet long by 450 feet feet wide. Two aluminum towers, each 151 feet high spaced 150 feet apart support this antenna. The frequency coverage is 6.2 to 30 MHz, horizontally polarized, nominal 15 dBi gain, 13 dB F/B ratio. The take-off angle varies from 13 degrees at 30 MHz to 20 degrees at 6.2 MHz. The beamwidth of 64 degrees at a bearing of 135 degrees true, provides coverage from 103 to 167 degrees; this includes the Southwest USA, Western Caribbean, Mexico, Central and South America and the Eastern Pacific Ocean.
