It is 0 at reset.

No. We typically do that on the host in software.

Use the normal set_freq method as in usrp

Can you give us the output of dmesg? It might give us some insight in to an
error thats occurring.

Dear Sirs,
I have two questions on USRP and GNU radio use.

I would like to record data into files. I am now using

I want to change the program that i
