Chart 4-4: Crossover Point and Operation Example on Map
No matter what instruments you use, locating an interference source is always a
work which combines theories, experience and technology. So it needs practice to
improve the efficiency. After several tests, especially the tests in cities and mountain
areas, there will be various illusory directions because of signal's diffraction and the
reflection.
* For the narrow-band signal, the interference source will have higher response
speed by being searched in field strength mode.
* When testing the emission field around radio station's antennas, field strength
mode must be used. The medium frequency gain in the frequency spectrum mode
should be set by users themselves, but keep in mind that it may be broken by the
strong signal because of the wrong setting.
Warning:
Unless there is permission, DO NOT test the space frequency spectrum of the
non-working frequency with KC901V. Even you test it accidentally, don't pass it on
other people.
