Alerting

Special Alerting Tones

No one wants to listen to people chatter all night while they try to sleep, leaving their radio on due to the incoming storms.  Well, we have solved that problem by implementing three methods of paging!

Method one: Long tone.  Set a channel in your radio to listen to 147.255 but only open squelch for a long tone of 1745hz.  This will be sent when spotters are needed and/or when we move to full activation.  It can also be activated in the event of a non-weather emergency where a message needs to be transmitted to local hams (think mass causality incidents, etc).

Method two: Two tone. Set a channel in your radio to listen to 147.255 but only open squelch for a two tone page: tone 1(A): 1000hz tone 2(b): 455hz.

Method three: DTMF.  Set a channel in your radio (most Yaesus, Icoms, Kenwoods, etc do this) to listen for “DTMF Selective Calling.”  The tones are ” 0 0 0 0 ” (Four DTMF zeros)

When a page is sent out, all three above methods are used, in the order they are listed.  This allows different radios/pagers to be used.
