Im inerested in finding out how to build a AM frequencie jammer. Its for a senior prank at school, and it would be helpful not to be seen by security. I heard that tv is transmitted in AM waves, so in theory, a AM jammer would render a cctv camera innefective. Right? reply to tommygunn9820@yahoo.com

Where can I buy a jammer for fm/am and shortwave? How much $ will it set me back? Thanks.

Since I haven’t picked up a JTOS-150 Oscillator yet (75-150mhz) I pulled a little 49mhz chip from a radio control car’s remote and was wondering, how do i wire the antennae to it?

How about AM radio jamming? I have a problem with AM radios of the guards at the first floor of the building waking me up at 5AM.

I have been reading on fm jammers just to get a peak at what “The incognious peoples of the world have against, poor old me.”

I was wondering if there are any easy schematic plans on how to build an FM radio jammer, something that can reach 88.0-108.0 MHz’s, or higher would be helpfull.

Please send via EMAIL:

Thank you

i asked for them in a free samples request somewhere on the site, it took almost 6 weeks though….youd be suprised how much free stuff you can get

I’d assume you’d just use a 4046…

Question; how’d you get free crystals from fox electronics? o_O

i just wanted to say that i got 5 free 100mhz oscillating crystals free from fox electronics. I hooked up everything as shown on the afro site, and nothing except a little distortion on 100mhz…..so dont waste you time with his design. Windwaker what ic would you use, and do you have a schematic/plans???

I ordered the 100mhz in and powered up, just as I thougnt, only oscillates at 100mhz, nowhere else. waste of time and money. Don’t be fooled B.S. -Bad post

If there’s no way to block frequencies about 2 away from 100, you’d have to match two crystals and use an IC to make the resistance go up and down constantly.

I don’t know if anyone is still interested, but i think i may have found some.

Not with one, but if you have ten of them, yes. :P
