append "digital" to this line:from gnuradio import gr, gru

ie.:from gnuradio import gr, gru, digital

Subject: USRP more than one channel demod
Message-ID: <926F9B6B6CAE40D684A6FEFB3BAA20AC@pc1>

Hello.

Has anyone an idea how to demodulate more than one channel per time while using an USRP or FCD?
The provided bandwidth is big enough. But how the split the 25kHz channels into seperate streams? Any idea is welcome.


Thx

Martin

Hi Martin,
i have the same problem.
In my area there is only a tetra network, but there are a lot of BS,
so from my house i receive 5 different frequencies of the same
network.

I'm developing a little mod for the qthid that analyze if on a
frequency there is traffic, and if not, switch to the next frequency,
and continue in loop until on a frequency detect traffic.

When i finish it, i share with us.


Excuse for my bad english but i'm italian...
