[Discuss-gnuradio] NFM TX with branch "next"?

Hi, A few days ago I tested the latest "next" branch, now it builds on a 32 bit Kubuntu 12.04 without any problems - but it seems to me that still the good old analog stuff is not completely supported, or am I wrong? Just needed a dual tone in NFM, so I put together two signal source blocks, an ad

OK, I will give it another try, but I wonder if it may have to do with grextras not being compatible with the new API? There are two NFM TX blocks available in my installation, both do not work under next, but with different errors. After the next try I will give exact copies of the messages..

Hi, I've managed to install gnuradio from source before I installed the UHD driver from ettus, and now gnuradio cannot find the uhd source and sink blocks. After looking in the directories for the installation, I cannot find uhd files such as usr/share/gnuradio/examples/uhd. Furthermore, in pytho

Hi Jeff, If you are compiling GNU Radio from source you need to install the UHD first otherwise it will not compile in the necessary components. If you already have GNU Radio installed from source, you will need to uninstall GNU Radio, compile and install UHD followed by compiling and installing

Replace the low pass filter with a band pass filter. The low pass filter is not extracting the signal at the center frequency, but the first 70KHz of the 1MHz bandwidth. Also, the decimation and interpolation chosen in the resampler will destroy all information in the channel. At the chosen v
