View Full Version : Page tone monitor

Tue 10th Nov 2015, 03:39
I am new to this forum so I hope I am doing this right, I am trying to build something that will essentially act as a Minitor V (page monitor). I am on a volunteer fire department and I thought it would be really neat to be able to attach a pager to a relay (and run some lights and stuff). So what would be involved in building a monitor/receiver that would detect a specific page tone? I have not really done any electronic engineering but I have an interest and I always want to learn more!

Thanks in advance!!
