Why I ordered a raspberry PI Things are complicatiatetered But I need to jtag FPGA board from my laptop.. This FPGA JTAG cable is for a parport. But raspberry PI has an IO header.. Also speed.. and via network, webpack is on yet on other PC here. The second plan: being able to record IQ signals for almost any frequency band you can think of, especially tried GPS, I was wondering if I could do an universal replay attack by playing back the IQ via a quadrature modulator setup [1], so dual DAC, QAM modulator, thinking about these 2 chips: AD9761 Dual 10-Bit TxDAC+ with 2 Interpolation Filters AD8349 700 MHz to 2700 MHz Quadrature Modulator This will require a very precise replay at exactly the same 2048000 sample rateI recorded at. But it will also create a DVB-T TV modulator as a side effect (with somesoftware), at the final frequency, so no up-conversion. Anyways a replay of those secret NSA CIA transmissions, or providing the white house or wherever coordinates to local drones using GPS, or retransmitting a full 1 MHz wide broadcast band .. The other thing for the PI is to use it with the DVB-T stick as small portable spectrum analyzer, just port my software to ARM, and add a LCD display... Would make a GPS too, of software defined radio, or... I wonder if I have to add some hardware FIFO (FPGA?) to make regular samples... [1] will my noise (spread spectrum) when stronger then the normal signal noise, that is below thermal, replace the whole constellation at once? Anticipation. ;-)

think of, , e rate I recorded at. software), g GPS, table les... noise, seen the Pcduino? it's a bit more expensive than the raspberry pi, but it's got 1GB ram, 2GB onboard flash and ADCs and I think you can actually get a datasheet for the CPU -Lasse

It's similar (perhaps slightly darker and a bit more red) to the color Subway uses to drive customers out of their seats in minimum time.

Are you trying to drive people away from your site?

Just the talk of it worked.

using GPS,

Given the number of people doing on an ongoing basis for years, i doubt your assertion. How about you find some king of backup.

GPS,

It would be nice to have a badge that says "Spectrum Enforcement".. I guess I'd need a black suit too.

Sufficient. Notice that this guy was hammered for importing them for sale. There are still plenty of people that can home brew such a device. The FCC normally does not go out hunting an illegal emitter without sufficient complaints.
