how many milihenry?Without C2 the circuit will not oscillate. My stereo picks up CB radio from passing trucks.
If you’re only interfering with your own radio, it should be alright in most places. tune FM radio to a station now switch on the above circuit adjust C1 till the FM station is blanked with the carrier beat.if I cannot find 16awg wire which alternative can I use? ?16 awg is difficult to be found.hi can u please give me value of L1 in henry?so that i can directly use inductor having that value?It is very interesting and I like this circuit as it is very simple. Hope I cleared some of your questions out … CheersWhere connected earphone in this circuitcan u pls explian the the operation of the circuit like how the current flows from battery to till the end what is the function of all capacitors and resistors?what if I connected a fm transmitter to the fm radio jammer would the wireless range changewould you have to adjust the Fm radio jammmer’s varaible capacitor every time you changed the station on the radioHi without emitter resistance the transistor will blow of. If you’re intentionally interfering with other peoples’ radios, then it’s illegal almost everywhere.Kindly do tell the number of turns and diameter of the inductorsir can you provide me a circuit for jamming mobile phone….. i.e the GSM frequency band..can i make a 6 turn coil from jumper wires or internet cable wires?? Cobra 29Lx Professional CB Radio - NOAA Weather Channels and Emergency Alert System, Selectable 4-Color LCD, Auto-Scan, Alarm and Radio Check 4.2 out of 5 stars 1,052 $149.95 $ 149 . The guy that needs to play with his echo for hours on end. please give the schematic to jamm all the frequency because this is my final project for my subject. According to the characteristics of the signal blockers the jammers have been divided into different catalogs such as the 4G/LoJack/XM Signal Jammers, UHF/VHF Signal Jammers, RF Signal Jammers, Wireless Video/Audio Signal Jammer, Cellphone signal jammers, GPS signal jammers, WiFi/Bluetooth signal jammers, for car using and so on.All the signal jammers offered here are designed with high technology and high quality and aiming to creating more convenience and give more help to people. All of those things to me are part of radio.A day later the same thing was happening and I went over and kindly asked them if they would change to another channel and they happily complied.To do this effectively you’ll need a very good setup with a good antenna. Now throwing a deadkey isn’t the best thing for your radio because it creates heat and wear and tear on the transceiver. The one thing I always tell people is don’t go calling the FCC and complaining about a troublemaker.

Adding another transistor as Rf amplifier?what is the wireless range for this circuitWhat is the use of the C2 capacitor, the one with a 6pF capacity?I’d like to ask something about the capacitors. Portable 3 Antennas XM Radio LoJack 4G Mobile Phone Signal Jammer. The project uses a 100 MHz crystal which I haven't seen, the page goes on to say that it was procured out of some old circuit board from the 90s. Also, I couldn’t find a 6pF for C2. CB radio was a fun pastime for myself and my teenaged cohorts in the mid 70s', and as young adults in the 80's and beyond. How you do the coil doesn’t seem to matter much because you set the frequency from the capacitor.Hi Bryce you can try with one of the supplierswhat if you doubles all the capacitors Uf’s and transistors current will the wireless range changeHi Bryce it has to be in the range of 3 to 35PF.
4.6 out of 5 stars 2,823. Build your own miniature jammer system. Especially if your station is louder. Don’t forget to go pick up your jammer later and don’t try this one if it’s raining.Build your own miniature jammer system. This is best done with a fully charged older car battery, small radio such as a Uniden Pro 510 or Cobra 19 (or any other small cheap ass radio) and a simple fiberglass antenna (2′).The deadkey. Add To Cart. US$162.83 US$148.90. But at least you can go home and talk on that channel You set up this little transmitting bundle someplace very well hidden (maybe in some woods) within a block of the offending CB’er and then turn on the radio and tape down the microphone key with some electrical tape (wrap it around the mike good).Troublemakers are like bullies.
