Computer-control Software
Some modern amateur transceivers have embedded computers with firmware which is executed to provide the functions and features of the transceiver. This software must be provided by the original manufacturer of the equipment. Another type of software is that required to control a receiver (or transceiver) without a front panel provided. Examples of this are the Kenwood TS-B2000 and the Ten-Tec Pegasus; both transceivers are sold with PC software to provide the human interface for operation. Most transceivers with front control panels (and many receivers popular among shortwave listeners) have a computer interface such as a serial port, USB or Ethernet port. These ports are useful for satellite-tracking frequency control (Doppler tuning), station logging, digital operation, internet and special-needs accessibility. In many cases, the software adds improved or extra functions and features beyond that provided by the original design. For this reason, some operators purchase radio-control software for non-computerized operation even if their radio has a front control panel.
