  1. Thanks, yeah I'm nearly there it's a tad frustrating... The manual option doesn't do anything, that's how I started, by changing the manual gain numbers, to no effect. I'm wondering/hoping if there's a filter to be applied immediately after the source, to bring the gain down, my fear is tho, that the damage has already been done as the output leaves the source widget in gnuradio.
  2. Hi All, After testing the rtl_fm command with my new rtl8232u, to ensure the dongle can in-fact tune in to other frequencies... I've followed the tutorial on creating the FM radio in gnuradio-companion, but no matter what frequency I tune to, the audio, and instrumentation, output is the same, just white noise. I then read in the documentation that the "Gain Mode" for the source dongle can only be "automatic", by default it's "manual". When switching to Automatic, the gain is waaaaaaay too high, the sound is distorted, with the waterfall output pretty much solid bright green. But at least then I can actually tune to different frequencies, so know it's working. I surely can't be the only one experiencing this, I've checked and double-checked the tutorial to ensure I'm doing everything exactly the same. Any clues?
