 **Oscillation** - A repetitive variation (usually in time) for a measure or value about a central value, e.g. a sine wave oscillates regularly between two peak values (positive/negative) about a central value of zero.
+**Packet** - in the context of amateur radio, refers to [[packet|packet radio]]. There is a glossary of packet radio specific terms [[packet:glossary|here]].
 **Polarisation** - The property of a wave (usually transverse) that defines the geometrical orientation of the oscillation of that wave, e.g. a sine wave could be said to have vertical polarisation.
+**POTA** - Parks On The Air.  (https://www.parksontheair.com).
 **Propagation** - Any of the ways in which waves travel. Electromagnetic (radio, light etc.) waves can travel in a vacuum; sound waves by comparison cannot.

 **Sensitivity** - The ability of a receiver to detect weak signals.
-**Voltage** - A measure of the energy possessed by a quantity of electricity: a source of energy of one volt is able to deliver one joule of energy for each coulomb of charge that flows. It is measured in volts, V.
