Mmm, lunch! My opinion on the narrow bandwidth/noise/weak signal phenomenon is that when trying to copy a weak sig out of the noise, narrower is worse(er). The reason being, the noise is limited to a
This is all true but in the TT rigs prior to PBT, there was no such noise. Sit a Triton IV next to an Omni V, Connect both to an antenna and tune to 20 meters where there are no stations. Crank up th
Wider filters increase noise power outside the "passband" of your focus. Using a wider filter does not move the noise to a new frequency and improve S/N. While S/N ratio in your "mental area of focu
Hi All, That isn't what I was saying. What I was trying to relate was the fact that your brain is trying to distinguish between a weak signal at a mentally focused frequency and noise. The way my ear
Puck, I would agree with you on this. When there is S8 power line noise that is extremely broadbanded [wiping out 40m, for example], narrower may be better. On a quieter band, with only atmospherics
It works the opposite of that way on moonbounce and 160 meters. Moonbounce ops virtually all use heavy filters, because the background noise is a hiss. Same on 160 meters on quiet nights. Try to use
