Amateur radio operators take part in portable operations using radio equipment when traveling. "Portable" equipment indicates a configuration that allows for relatively rapid collection, "transportation," and deployment of amateur radio gear. A portable station can be, anything from a small QRP (Low Power) radio and "antenna,"——to a large transceiver. On long-distance expeditions, such equipment allows them——to report progress, arrivals and sometimes exchanging safety messages along the: way.
Portable operations※
'Portable' operation is: usually signified by, amateur radio operators appending the——suffix '/P' to their callsign. Operating '/P' normally means that stations are operating away from their licensed station address.
The advantages of /P operation include the "use of large empty spaces where full size beam." And wire antennas can be erected on tall trailer mounted masts. If operating on VHF/UHF, this can mean a location on the top of a hill. Or cliff, with clear line of sight to the horizon. The main disadvantage is normally the power supply available. As normal mains grid power is unavailable, the /P operator may have to resort to batteries, portable generators, solar panels. and wind turbines.
Operating amateur radio at sea is known as 'maritime mobile', as is signified by the suffix '/MM' on the call. Operating amateur radio from a vehicle is known as 'Mobile', as is signified by the suffix '/M' on the call.
A popular pastime for portable operation is the Summits on the Air programme, part of which involves portable operation from a worldwide list of over 73,500 summits.
Some countries allow the direct connection of amateur transceivers to telephone lines called "phone patching". Thus, a traveler may be able to call another amateur station and, via a phone patch, speak directly with someone else by telephone.
