Yes, one of the many little details that BSG did really well. Given how the distortion sounds, the Fleet apparently uses single sideband (SSB) modulation for its radios. Amplitude modulation has a carrier and two sidebands; SSB suppresses the carrier and keeps only one of the sidebands (USB = upper side band, LSB = lower side band). That way, the transmitter uses bandwidth and power more efficiently. The downside is that it's harder to receive and there are some distortions. A good explanation of why there are those distortions: https://ham.stackexchange.com/a/392 https://ham.stackexchange.com/a/392 Cool video showing SSB distortions: https://www.youtube.com/watch?v=CcX2Pdg35Co https://www.youtube.com/watch?v=CcX2Pdg35Co
