Re: Sample Rate and audio underflow ....

Hi Rob - you should just post the GRC file to the mailing list - just attach it to the message. If the only thing you changed was sampling rate, then you will most likely have trouble.  But you haven't provided enough information in order for anone to help you. Note, the website in the

Hi Bruce - if you only have 1 HackRF One connected the computer, then you can just leave the "Device Arguments" blank. Otherwise, take the last 8 characters of the serial number - not the entire serial number. -- Cinaed On 5/13/21 1:27 PM, KG4HLZ wrote: Gnu Radio noob here. I am trying

Re: using gr-specest/gr-inspector

Hi Marcus, Thanks for the reply. The reason I am sticking with GRC 3.7 branch is that the AMC block is present only in the gr-inspector 3.7 branch, which requires a CNN graph for input, I have no issues in running the 3.8 branches of the OOT. So, if this is the case is there a way I can import a

using gr-specest/gr-inspector

Hi Aditya, you shouldn't use GNU Radio 3.7 for new things in 2021, it's a dead end; we don't develop this any further, and it will not work on newer machines; there's nothing we can do about that. Both gr-inspector as well as gr-specest work with GNU Radio 3.8, if you check out their

[no subject]

Hello, I am working on AMC(Automatic Modulation Classification) using GRC. After some digging around I found that gr-inspector along with gr-specest will work for this. I also found that while using gr-inspector I need to check out the maint-3.7 branch (gr-inspector for maint3.7 says that a

Sample Rate and audio underflow ....

Hi all! I'm working on a "Hello, World!" flow in GRC just a simple NBFM receiver tuned to my local NOAA station. Using an RTLSDR and the osmocom block ... into a low-pass that decimates by 5 into the NBFM block and then an audio sink. It doesn't get any more simple. Here is a image of the

GNU Radio UX Studies - first study - can we improve the way to create a new flowgraph?

Hello all, Our first GRC UX study has started. It's to understand how the current create new flowgraph process works for users. We think there are some improvements that can be made to it - some steps cause great confusion to some users, others take a lot of unnecessary time for more

embedded python blocks inside hierarchical blocks

Hi all, I noticed the following discrepancy between how 3.7 and 3.8 treat the above blocks: When I generated a hierarchical block in 3.7 with an embedded python block in it, the generated code of the embedded python blocks (epy files) were copied to the .grc_gnuradio directory. In 3.8 the
