hi ever one
i am looking to make a transmitter that i can here on LW MW or FM just to recive a bleeping signal over a distance of about 30 meters on ground.
all i want is a simple transmitter i can use to alert me to a rat trap i have made so when a rat gets trapped it will allert me so i can go and let it out somewhere else.
i have made both of these schematics but they never worked for me
any ideas please
