Category: RF Circuits / Jammer Circuits This circuit is also crossed to: PIC Microcontroller Views: 2290 Rank: 0 GPS trackers as GPS vehicle tracking and person monitoring tracking can be used in a good way but sometimes they are used in bad way. These tracker units monitor the exact location of you, and then deliver that information to a second part. If you don’t want your location is track able then GPS jammer will take care of that.GPS jammer is a high accuracy RF system using PLL controlled VCO with 3.4 W power output. It can create black spot that blocks all known GPS trackers on the market. This PIC16F870-based GPS blocker works with jamming range 1000-2000 feet. The main part of this project is a VCO, PIC 16F870 and a PLL LMX2322. The device is powered by 9V battery and it has small size, you can put it in your pocket visit page.

Related circuits A reference schematic, not been built. TV remote control Jamming circuit Just point this small device at the TV and the remote gets jammed . The circuit is self explanatory . 555 is wired as an astable multivibrator for a frequency of nearly 38 kHz. This is the frequency at which most of the modern TVs receive the IR beam . The transistor acts as a current source... Hackers listen up. Everyone understands and enjoys the utilitarian benefits that GPS has brought to our lives but what if it didn’t work any more? I suppose you could build some sort of surface to space missile robot that would systematically seek and destroy all the GPS birds in orbit, but... RF input about +10 dbm. Preamp. Main Amplifier. RF output nominal ~ +33dbm (max ~ 3.2 W). Also you can see the FB going to contact (3) so you only have to solder a small FB to contact (2). Cut the PCB like in the picture 4 or 5. The amplifier from old Siemens Cellphone work well with the VCO. The... This cell phone jammer is not applicable for use in Europe, Middle East, nor Asia. The GSM jammer circuit could block mobile phone signals which works on GSM1900 band, also called DCS. For more cell phone jammers check the related posts. Remote control Infrared Jammer This Remote control Jammer device it’s useful when we need to block someone to use the remote control (children that change frequently the channels at tv). This remote control jammer it’s very simply and it use two infrared Leds which continuously transmit with a frequency between 32 and 41... A low cost device to temporarily disable the reception of the civilian coarse acquisition (C/A) code used for the standard positioning service (SPS) on the Global Positioning System (GPS/NAVSTAR) L1 frequency of 1575.42 MHz. This is accomplished by transmitting a narrowband Gaussian noise signal,... High power mobile phone Jammer circuit If we are speaking about professional Cell phone Jammers we are talking about this schematic below. First off all you should be very careful how to use this device. Its fully illegal and so the purpose I post this Circuit is only for educational and testing reasons. This type of device is being...
