How to make an intercom or walkie talkie(wireless)?

Answer 1

Just buy or construct two pair of FM transmitter and receiver. Use push to talk button to control the transmitter section; the receiver part always be on. Now make two set each containing one transmitter and receiver. Tune each receiver with other transmitter. Now your walkie tallie is ready for use. If you can use a higher and proper antenna then you will get more range, once I managed three hundred meters of range. Hope you will get more range!
