Hence my question of the OP - If this is the local volunteer fire
department siren alerting its members to respond to a fire, the
answer is a hard no as this is anther radio service.
No, it is not. It is a message from the repeater that the siren has been activated. The message transmitted could be anything. It is no different than an operator keying his microphone and making the announcement. It is emergency traffic.
If this siren is activated via an NWS SAME alert to warn the
population at large, IMO would make more sense to feed the alert
into the repeater audio chain, with the ability to silence it with
DTMF or even a triple-click of the microphone.
There are those here who, wrongfully, say that isn¡¯t legal. It is 100% legal.?
97:115 does not apply since it is not third party communications. Emergency communications from any source can be retransmitted.?
