John, let's talk about antennas first. What kind of antenna are you using and how high is it? Man-made noise is usually vertically polarized, which means a vertical antenna will pick up more of it than a beam or a dipole. Also, the lower you go in frequency, the more atmospheric noise you get. Man-made noise responds better to noise blankers than atmospheric noise. Sometimes, DSP can help.
Since you're talking about 30m, you're working CW or a digital mode. Use the narrowest filter you have. Same signal, less width for noise, better signal/noise ratio.
Best regards,
