Hi everyone,
My understanding is that the constellation modulator block should output an
RRC pulse in the real and imaginary domains according to the constellation
points. The pulse amplitude can either be positive or negative.

traditional dB formulae i.e. 10log(input), or 20log(input).

Hello Everyone,
If you run following code on your machine (I am using gnradio3.1.1 and this
code is also available in this version with a name 'fsk_loopback.py'
although it is removed in gnuradio3.1.2) then you will see that it will
transfer a file send.txt (Please create file named as "send.txt"
),
Gain = 0, but I have tried other values [0-20].
Thanks

If someone has ever measured Quality of service of received data (using any
modulation and daughter board but preferably RFX2400) in terms of packet
loss rate/Bit Error Rate (or any other metric) with USRP & GNU Radio without
any error correction (ARQ,FEC) mechanism (but no problem if you have wit
d it empty.
What can be the problem???
