hat
Siyal nan transmèt yon ton modulation ak yon konpayi asirans, pou ke li ka fasil pou tande lè l sèvi avèk yon reseptè AM òdinè. Li te ansyen lajman itilize pou idantifikasyon estasyon nan alèksyon ki pa direksyon, anjeneral, men se pa sèlman Morse Kòd (yon egzanp nan yon modil vag kontinyèl, kòm opoze a A1A, pi wo a).

Signalling by transmitting a modulated tone with a carrier, so that it can easily be heard using an ordinary AM receiver. It was formerly widely used for station identification of non-directional beacons, usually but not exclusively Morse code (an example of a modulated continuous wave, as opposed to A1A, above).
