Communication is the major problem during catastrophe. To address this problem the technology called amateur radio is used. During calamities and natural disaster times, amateur radio is recurrently used as an emergency communication system when wired line, cell phones and other contemporary means of communications goes down. This paper shows the design and implementation of wireless transceiver based on amateur radio. It also describes the concept of ham radio station. The blocks in transceiver can be exchanged to any other frequency band, so it is like a universal block design. The design of transceiver is made to work within 14 to 14.35 MHz high frequency spectrum of amateur radio. It outlines specially the transceiver and antenna used in ham station.
