Yes. I can understand the LFRX does not have any adjustable gain. But what comes out of the USRP source should be samples already digitized. Surely there is gain to be adjusted before the ADC. According what I see, it is from 0 to 6dB (in voltage?). I don't see how this can be inserted into the USR

Dear GRC'ers I am just starting to play with GRC. One thing I am playing with is the file sink. It appears there is no way to control the file size from its output. This can be dangerous but the continuous sampling at high rate can quickly fill up the disk and cause possible disasters. I am surpri

I recall running into this issue myself now, with multimode and simple_fm_rcv. What I do in those two apps is that when I turn "off" recording, I change the wavfile filename to /dev/null, which causes a formal cleanup-and-close of the previous file. On 27 Sep 2012 11:13, Anton Komarov wrote:
