Thanks Marcus. Time to put this to the test: https://imgur.com/a/hRsYAFu I need a way to test that the values I detect in java are the same values that I get in GR. I tried a Message Debug connected to the output of "Complex to Mag" but that gave me a red arrow so not allowed. Any suggestions?

Hi Al, you'll laugh, but under the hood, the rational resampler *is* a filter! And the way you configured it, it has very many taps. So, the correct solution is actually to reduce the taps. Let me quickly explain: Here's an example for a complex baseband digital signal; already sampled at a s

I am still trying to learn how GR works. Coming from Java the idea of being able to do some processing there interests me. So I am trying to use a baseband file from SDR++ as a file source, and process it in such a way that I can get the amplitude in Java. I presume this would mean reading in the
