So I built a circuit that reminds you that your leaving an object behind. I'm using the TWS/RWS-434 RF Link. I built it on a solderless breadboard and I get a range of about 7 feet or so. I'm supplying the Transmitter with a 3v battery, the Receiver with 5v and no optional antennas connected. BUT then I built it by soldering it on a protoboard and I only get about a 5 inch range, THATS right a 5 INCH range! This is with the Transmitter running at 3v, receiver at 5v and no optional antenna just like the breadboard! So I'm scratching my head, this doesn't make sense. Why? I supplied the transmitter with a 6v and it seemed to get a little further range. But It just doesnt make sense, why would it be a farther distance on a breadboard and not on a prototype board with soldered parts.
Can anyone help me?
