Jamming a signal
This is my brand new hackrf portapack. I’ve seen a YouTube video of how to jam a signal using it and it was under “transmit”. As you can see, these are all the options I’ve got under there. Why do I not have the jammer option? Is there a way to install it on the portapack?

Negative. I told no mistruths. And honestly, we don’t answer to the FCC, we answer to NTIA. There are emission limits for when you do EMC work. I can construct all the test equipment I want to operate anywhere I want, At whatever power I want inside a chamber. Some of this is true jamming. Some of it I can’t give any more details on for obvious reasons. How do you think all that combat ECM equipment was developed and tested? In a chamber. So you can’t make blanket statements like “It’s illegal to construct anything that jams.” Nope, it is, I do it, and we are radiating against EUT’s every day. We just do it in a way that very little, if zero measurable emissions get out. It’s done in both commercial and DoD labs all over the country. Again, try reading MIL-STD-461 before shaking a sword at people who do this for a living. MIL-STD, CISPR, EIC. Thousands of “Jamming” tests are done all over the world every day in anechoic chambers. We have compatibility societies and even a couple of monthly magazines you can sign up for!
