One of the key areas of any radio system is that part where the signal is transfered from the transmitter to the receiver. This involves the use of antennas or aerials to radiate the signal as an electromagnetic wave, and then there is the way that the electromagntic wave travels or propagates between the transmitting antenna and the receiving one.

Most electronics constructional projects involve at least some degree of soldering and wiring. Many projects have a printed circuit board, PCB, forming most of the project, but it is necessary to connect the PCB to other controls and sockets, etc elsewhere within the final project. The connections that are made to many of these items will be exposed.
