description

The Kyodo KG510 transceivers represent a quantum advance on the previous rugged & time proven KG110 transceiver. They comprise of separate modules all housed within one 2RU equipment cabinet. The receiver, the transmitter, and the PA Unit are each enclosed within their own diecast housing, which are then directly mounted on the large upper heat-sink. A μProcessor controlled interface module controls the channel selection, LCD Display, timers, interfaces, and signalling features.

Models are available for all FM commercial and military frequency bands from 30 MHz to 520 MHz, with channel selectable 12.5, 20, 25, or 30KHz channel spacing arrangements.

The RF Power Output is 1 - 50 Watts on a continuous duty basis. The CTCSS signalling supports all EIA tones. Different encode and decode tones can be set on a per channel basis during radio programming.

The KG510 includes 5 tone Selective Calling encoder/decoder with non-predictive decoder, as well as a DTMF encoder and decoder, and voice encryption. It supports normal all channel scanning and programmed channel scanning for base use.

The KG510 is fitted with a large full dot matrix LCD that is used to display the Channel Numbers & Names, frequency & tone programmed information, and Signalling information. All user interface keys and knobs are conveniently located on the front of the radio. All user-entered functions are easily activated in a logical manner via the keypad.

The KG510 is supplied with an "N" Type connector for the transmitter, and a BNC Connector for the Receiver to allow easy connection to the diplexer or feeder cables.

The rear panel includes a 9 way and a 25 way D sub connector that allow easy connection to external accessories such as other radios, control equipment or shared tone panel.

The KG510 is PC programmable through the rear connector. The programming software sets Channel frequencies, Channel Names, CTCSS or DCS frequencies, Start Channel and Start Message, the KILL security feature, and Signalling parameters. The software includes a memory check function and a WatchDog Timer.
