Thank you for following up on this issue. The grc cache has turned up a few times recently as the cause of a few issues. So yes a github issue would be a very good idea to track this. Thanks! On Sun, Apr 25, 2021 at 3:52 PM Christophe Seguinot < christophe.segui...@orange.fr> wrote: > Hi > > I e

It definitely helps, thank you. One thing I noticed, and don't know how to address is why the ""Correctly Sampled Signal"" Time Sink shows the amplitude on the nanoscale.My signal source has an amplitude of one and the Time Sink should be displaying a range from -1 to 1. I placed a rational resamp

Hello GNURadio Community: In my GRC signal flowgraph, I would like to make use of a complex value computed down stream to multiply upstream input values. Gnuradio has a "Multiply by Tag Value" block which I think would work wonderfully, if I knew how to use it. I am building an OOT downstream blo

Hi I effectively proposed Mike to remove the cache.json file, in case it could help. As I thought this was probably not the solution I sent him a private email and asked him to answer to the list in case of success. So to resume; it appears that the problem originates from simply upgrading G

With thanks to Christophe for his excellent advice, removing ~/.cache/grc_gnuradio/cache.json fixed things up. After needing to do this now & then, I have a new gr heuristic: if (weirdnessReigns) { delete cache.json; } Thanks, Christophe! Mike On 4/24/21 2:55 PM, Mike Markowski wrote: Som
