'''PACTOR''' : An FSK mode that combines packet and AMTOR technologies.

'''[[Dish or Parabola | Parabolic Antenna]]''' : An antenna in the shape of a dish with a parabolic cross section.

'''Parallel circuit''' : usually used to describe a tuned circuit in which the capacitive and inductive elements are parallel to each other.

'''[[Electromagnetic Waves |Period]]''' : the time it taks in seconds for a complete wave to pass a reference point.

'''[[Codes and Alphabets#Phonetic Alphabet |Phonetic Alphabet]]''' Specific, easily identifiable, non-confusable words are used instead of the letters of the alphabet.

'''[[Attenuators | Pi pad]] ''' : one of the possible configurations used in [[Attenuators]]

'''Polarization''' : Used to describe the orientation of the electric field produced by an antenna compared to the surface of the Earth.

'''[[Portable antenna|Portable]]''': A mode of operation in which a station may be moved for rapid deployment from a temporary location, but is not able to operate while mobile. In CW, portable operators may identify using /P. Portable stations differ from mobile stations in that large antennas or other structures must be folded or stowed away in order to move the station to a new location. While well-suited to [[field day]] or emergency/disaster operations, portable stations normally do not have a mobile station's ability to continue transmission while in motion.

'''Power''' : The rate of energy consumption. Calculated by multiplying [[Voltage | voltage]] by [[Current | current]], P = VI

'''[[Propagation]]''' : How well a signal is transferred from the sending station to the receiving station, as a function of the path type (ground wave, sky wave reflection or direct line-of-sight) and related atmospheric conditions.

'''[[Modes#Phase Shift Keying (PSK) | PSK]]''' : Phase Shift Keying - a digital mode.
