chifukwa ndi Wotumiza wailesi ya FM m'malo mwa wailesi ya AM mu tchalitchi choyendetsa? Zimatengera momwe amagwirira ntchito.

Ma FM amatanthauza kusinthasintha pafupipafupi, pomwe AM amatanthauza kusinthasintha kwa matalikidwe. Amasintha ma signature m'njira zosiyanasiyana. FM imatumiza ma siginecha kudzera pakusintha pafupipafupi, pomwe AM imatumiza ma siginecha kudzera mukusintha kwa matalikidwe, zomwe zimawapangitsa kukhala ndi mawonekedwe osiyanasiyana:

• Monga FM ili ndi bandwidth yapamwamba, wailesi ya FM imamveka bwino kuposa wailesi ya AM;

• Poyerekeza ndi AM, FM sichimakhudzidwa kwambiri ndi kusokonezeka kwa kusintha kwa matalikidwe, kotero chizindikiro cha FM chimakhala chokhazikika;

• Kuwulutsa kwa AM ndi mafunde otsika apakati komanso aatali, pomwe FM imawulutsa ndi ma microwave othamanga kwambiri ndi mafunde afupiafupi, kotero ma siginecha a AM amatha kupita patali, koma ma FM amatumiza mtunda waufupi.
