[Discuss-gnuradio] Adding Attenuation in GNU radio

Hello, This may seem like a really simple question, but If I wanted to attenuate my signal coming out from a USRP source block in GRC, say by 80 dB,, how would I go ahead and do that? Would I just add a multiply constant block after my USRP source block to scale down the incoming signal's

Re: [Discuss-gnuradio] Runtime AttributeError for custom block

I missed the link in my earlier post. This is the SWIG tutorial I followed: http://www.swig.org/Doc1.3/Python.html. On Sat, Jul 15, 2017 at 10:02 AM, Vipin Sharma wrote: > I spend some more time on figuring out what is going on. > > It looks like the SWIG example

Re: [Discuss-gnuradio] Runtime AttributeError for custom block

I spend some more time on figuring out what is going on. It looks like the SWIG example from () works properly. I am able to check if SWIG has correctly incorporated the 'example.c' extension: >>> import example >>> example.fact(4) 24 >>> dir(example) ['__builtins__', '__doc__', '__file__',

Re: [Discuss-gnuradio] Sampling rate / frequency issue

Hi, Sorry, just realized that decreased bandwidth = decreased signal to noise. Had a memory slip on that one! But I am still interested in the main part of the question. Thanks in advance! Ellie On Sat, Jul 15, 2017 at 11:13 AM, Ellie White wrote: > Hello! > > > > I

I've tried to unsubscribe and keep getting posts. The unsubscribe system goes through the usual steps and looks as though it's OK, but it's not. Please add that to the trouble list. Thanks - DavidC KD4E Over the past few days, we have had a number of reports of issues posting to the list. We

[Discuss-gnuradio] Sampling rate / frequency issue

Hello! I have a quick question to ask, related to sampling rate and observed frequency on the waterfall sink. I’ve been testing an antenna (connected to an SDR dongle) with both GNU Radio and SDR#, and have noticed something kind of odd. In SDR#, I can see some strong signals at ~125040 kHz

Hi Richard, strange errors. Any chances that you have another (old) installation somewhere on your system? Best, Bastian > On 14. Jul 2017, at 22:36, Collins, Richard > wrote: > > Hello, > > I'm having trouble building Bastien Bloessl's csma_and_agc branch
