Radio Beacon Transmitter (100W,250W,500W)
FEATURE & FUNCTIONS
The KMW-RB series NON-DIRECTIONAL BEACON are general purpose, high performance and fully soild state transmitters providing 100W, 250W, 500W continuity output power.
The transmitters allow presetting of one fixed frequency between 190KHz to 550KHz RF carrier frequency in 100Hz steps by Direct Digital Synthesized(DDS).
User-friendly microprocessor controlled keyer capable of programmable generation 1,2,3,4,5 or 6 Morse letters or numbers, Characters selectable between 26 Alphabets, 10 numbers & 21special character.
And keying rate selectable from 55ms to 250ms, Inter Character Sequence Tone Time Period selectable from 1sec to 64sec.
The transmitters are designed to transmit either Carrier only signal(NON, A1A), Modulated signal by internal TONE keyer(A2A) and Modulated VOICE signal by external audio source within bandwidth from RF carrier frequency.
Also the transmitters are designed to operate without adjustment it operates with RF output power 100W, 250W, 500W for 50ohm from Antenna Matching Unit is used for the transmitters.
Remote Control interface can be excuted as parallel interface.
