Ham Radio Portable Station
An Ham radio station set up in a temporary location is referred to as a portable station. A portable stations might be established to provideemergency communications in a disaster area, to provide public service communications during a large organized event such as a charity bicycle ride, to provide communications during an expedition, or for the recreational enjoyment of operating outdoors. Portable stations include the same basic equipment as fixed and mobile stations, although transportation of the transceiver, antennas, power supplies or batteries and necessary accessories often influences the particular selection. Equipment that does not weigh very much, or that can be broken down for shipment or transportation in luggage is especially popular with amateur radio operators travelling on DX-peditions.
Most portable stations rely upon generator or battery power. Because this form of power might be of limited supply, portable stations often operate at lower transmitter power output to conserve energy.
Some portable stations append a /P to end of their call sign (pronounced as “slash portable”) to indicate their status as a portable operation. In some countries, this is a regulatory requirement, whereas in others it is done at the option of the operator.
