This portable AM and FM radio circuit is designed using the LA1800 IC
and some other external components. As you can see in this circuit
diagram the LA1800 manufactured by Sanyo Semiconductors , require few
additional components. The LA1800 am FM portable radio circuit needs to
be powered from a 3 volt DC power supply circuit.

You can use an 3 volt battery. This radio receiver circuit has a low current dissipation of 5.6mA for FM band and 3.2mA for AM band .Also the output signal is driven into earphone speakers , but you can use an additional speaker ( in that case you need to connect an additional small power audio amplifier).
