Aerials
The lead connecting earphones to your radio acts as an FM aerial
when plugged into the earphone socket. The lead should be extended
as much as possible to increase FM reception. There is a separate
directional aerial built into the radio for AM reception. To achieve the
best MW reception, it may be necessary to rotate the radio.
