Re: [Discuss-gnuradio] How to modify freq deviation in a FM radio?????

2009-10-27 Thread Josh Blum
My advice is to get this all figured out in software before using any hardware (usrps and spectrum analyzers). You can simulate the effect of changing the max deviation all in software using a noise source, throttle, nbfm tx block, and an fft sink (all in grc). I guarantee that changing max

I want to design a FM radio with freq deviation can be change. Then I tried to modified an example in GNUradio example folder which name "fm_tx4.py" in line61,let max_dev=5 to 50K,shown in following yellow label. but there is no change at all in a spectrum analyzer. Help me,thanks class pipeline(g

Hello, I do IQ plotting for DBPSK, DQPSK, 8PSK. (Please have a look below): For DBPSK: http://omploader.org/vMm16Zg/dbpsk_IQ_plotting.png For QPSK: http://omploader.org/vMm16Zw/dqpsk_IQ_plotting.png Can someone explain why for DQPSK positions of ideal points are wrong? It should be [1,1], [-1,1

I just want to do a demo about two radios in one USRP by time divition, both are FM&FH, but with the intention to distingrish these radios,the FM deviation and FH hop step should be different.Now I could control the hop step,but the FM deviation can't be controled(FM deviation should be12.5K and 25

If you installed via Synaptic you likely just installed the binary (i.e. pre-built) packages, which include the header files (necessary for building your own, custom blocks), libraries, and the applications/examples that come with GNURadio. If you want to modify the existing examples, you'll need
