I have changed it to WFM but that very noisy voice disappeared completely!
if the bandwidth of our local fm broadcasting is 200 kHz, isn't it the
FM rather than WFM?
No. WFM means "wideband FM" -- exactly what you want for broadcast FM.
Narrowband FM usually have a bandwidth in the 10-25kHz region.

Dear all,
I installed GR and UHD and everything works properly in GRC
but as i wanted to give "uhd_rx_nogui" a try i received a badly
noisy sound!
the command is this:
$uhd_rx_nogui -f 104e6 -m FM -A TX/RX
i am using b200mini and i can receive FM via GRC!
i searched a lot but nothing!
(by the way:
$gnuradio-config-info -v
3.7.12git-231-gefcfde0e
$uhd_config_info
linux; GNU C++ version 5.4.0 20160609; Boost_105800;
UHD_003.010.002.000-0-gbd6e21dc
and the OS is ubuntu 16.04, 64-bit
)
thanks in advance
regards
Ali

Also, for the FM broadcast band, you'll need to use WFM, rather
than FM---broadcast FM is a MUCH wider bandwidth than FM used for
two-way radios.
