TK-260G/360G in detail: Rugged Die-cast Chassis and Polycarbonate Case Construction The monocoque aluminum die-cast chassis-heat sink borrows a principal from aircraft construction for rigid strength. Surrounding this and forming an integral part of the chassis, is the super-tough polycarbonate case to provide years of durability. The heavy-duty belt clip and antenna mount are also integrated into the chassis for strengthened unit construction. Companded Audio for Improved Audio Clarity The compandor noise-reduction feature enhances audio clarity on narrow bandwidth systems and is programmable per channel. Voice intelligence components are amplified and compressed at the transmit end then re-expanded on the receive end to reproduce the original audio signal. Built-in QT and DQT Signaling Encoder/decoder function segregates talk groups so users only hear calls from their own group. Signaling AND/OR Logic For improved response when using combinations of signaling systems, squelch is opened when either one, or all, signal requirements are met. Built-in 2-tone Decoder and Encoder The decoder and encoder functions offer a 2-tone paging code assignable to any channel. An incoming message is signaled with audible and visible alerts. Wide/Narrow Channel Bandwidth The TK-260G/360G can be programmed for wide or narrow bandwidth operation per channel to accommodate all channel allocations now and in the future. Maximum 8-channel Memory On-board memory stores frequency and configuration settings that can be programmed using a personal computer. The mechanical encoder utilizes a special pin for the setting of 2-, 4-, 6- or a maximum of 8-channel (default) capacity for customized performance. Selectable Power Output Settings (High/Low) High/Low settings can be input for each channel by your dealer. The TK-260G can be set for 5W/1W and the TK-360G for 4W/1W. DTMF ANI Function A DTMF code can be encoded with "PTT ID" operation. "PTT ID" -- the traditional DTMF ANI unit ID -- is programmable per channel and sends ANI automatically on every PTT (begin of transmit leading edge code and EOT trailing edge code are both independently programmable). Additionally, each channel can have its own unique DTMF ANI number to suit a variety of custom applications. Embedded Message The radio's flash memory can store an electronic message containing owner identification, property I.D. numbers, user and department names, service records, etc. A radio can be electronically identified even if external labels, markings or factory serial numbers have been removed.
