now the MDC tones, depending on where you live and the fire/ems stations near you, you would need the frequency that will decode and activate your radios alert feature as if you were apart of a group that your being paged out if you understand that, like quickcall? im not familiar with the aspect of the HT1250, only used them, never really played with them and got all techi with it.QUOTE]
138kay research your answer. MDC (
MDC1200 Signalling) and quick call are two comepletly different signaling methods. now when it comes to MDC it is an AFSK (Audio Frequency-Shift Keying) data burst and not a 'frequency'
a MDC burst has actual information encoded in the data burst, 2 tone is just that, 2 tones in a sequence. the pager measueres the frequency of the tones and if it matches what is stored in the pager it goes off, there is no data encoded on a 2 tone page (aside from the sound of the 2 tones)
Bpd119, to properly anwser your question you need to provide more information as to what you are asking, can you describe better what tones you are talking about. thanks
