NEED: Schematics for building a broad band frequency jammer (FM 88M-108M)

Sep 18, 2004 48 Replies

While I never put it on the air, I did experiment with a wideband FM transmitter coupled to an AVR chip generating a long fast PN sequence. Worked pretty much as you'd expect. Broadband jammers do take a lot of power to be effective. Everything's permissable, as long as you don't radiate. :)

Learning to dislike kooks at an early age saves a lot of expense and aggravation later in life.

Don't get insulted, but is your job devoted to spreading ignorance?

Tell Me about your stopped to break the law.

My sympathies to your mother.

Appearances can be deceiving, or in your case, truly disgusting.

No, silly, that's the point. I'm _not_ about to dispense a compliment to a fuzzwit like that, thank you very much.

Regards, Rich

Does it make you happy to be not about to dispense a compliment to a fuzzwit like that?

There is this schematic of a tracking transmitter at Antoon's website at UOguelph. It puts out a pulse of RF every second or three. What you do is change the capacitor in the pulse gen so that it puts out pulses at high audio freqs. If the pulses are sharp, it will be heard over many channels of the band.

Another jammer is a buzzer with a dipole antenna of two wires a few feet long. But this jammer makes noise and is easily discovered.
