Looking for a way to be alerted when I got a hog in a trap. I need something like a pinger I can get on the scanner or something and it needs to work about a 1/2 mile thru trees. I thought about a GPS cellular alarm transmitter but its over kill. I do not need gps unless someone steals it I suppose. Anyone know of some kind of pinger already made that won't cause trouble? Or a simple circuit I can build to do the trick? Sure wish I had that one they are looking for.
Reviews report several folks using the above device installed on masts and such and getting ranges of between 1-6 miles between the sensor and receiver. Note this was for driveways and crap, but I am sure the sensor can be positioned in a way and the sensitivity turned down to only alert on something inside the trap. Sensor supposedly has a range of 500 feet. Might come back to a microwaved hog.
Cheers. -- Teamwork is a lot of people doing what I say.
Another thought to this is a circuit activated signal. The guys setup the the little "pinger" at ham expo's all the time. One wire somehow hooked to tho door so the circuit to the battery is connected and it will automatically start sending out a signal when you got your hog.
