|
| 2. | At Stanford University's 150-foot radiotelescope, radio noise is " a constant impediment, sometimes severe.
|
| 3. | And the signal would be faint and mixed with radio noise from satellites and stars.
|
| 4. | Radio noise might eventually hurt the study of giant clouds of dust and gas in space.
|
| 5. | Radiotelescopes there would be shielded from earthly radio noise by 2, 200 miles of solid rock.
|
| 6. | "' Atmospheric noise "'is radio noise caused by natural atmospheric processes, primarily lightning discharges in thunderstorms.
|
| 7. | The plasma does not broadcast high frequency switching noise and remains ionized continually, becoming radio noise free.
|
| 8. | This shows man-made radio noise in various environments is comparable to the galactic center around 10-200 MHz.
|
| 9. | The observations confirmed beyond doubt that sunspots were the source of the strong increase in radio noise.
|
| 10. | In early 1946 he turned his attention to sunspots as a source of strong fluctuating radio noise.
