Thank you for your help Johnathan. Looks like I figured out the issue with Alsa and opened the channels using alsamixer. I was choosing the wrong hardware and now I am using hw:00,04 which seems to work with sampling rate 44.1K.
command line: sudo ./tx_voice.py -f 991e5 -v -I hw:00,04 -M 1 I now get this on the terminal: gr_fir_fff: using SSE bits per symbol = 1 Gaussian filter bt = 0.35 Using TX d'board A: Basic Tx Tx amplitude 12000 modulation: gmsk_mod bitrate: 50kb/s samples/symbol: 5 interp: 512 Tx Frequency: 99.1M gr_buffer::allocate_buffer: warning: tried to allocate 992 items of size 33. Due to alignment requirements 4096 were allocated. If this isn't OK, consider padding your structure to a power-of-two bytes. On this platform, our allocation granularity is 4096 bytes. aO............................................................... ................................................................. ................................................................. ................................................................. ................................................................. ............................................ What I am trying to do now is to transmit whatever I play on the computer (songs) and receive it on a regular FM radio in the room. I see a pulse at the 99.1M frequency using the usrp_fft.py how ever I cannot hear anything on the radio. Could you please give me some guidance on that.
