View of the modulator

Double modulator (in fact two modulators in one housing). This modulator is managed with a micro-controller with PLL loop. It can operate in channels 1 - 69, and S1 - S38. The modulator can use 5.5 or 6.5 MHz audio subcarrier. Power: 8-12 VDC, 300mA. Two separate working channels in full TV band 1-12, S1-S38, 21-69. Digital TV channel displayer, test signal (two vertical strips and 1kHz tone), RF loop.

75 dBuV output level, no output filter (for output channels below S17 there is needed a band or low-pass filter, or channel amplifier). In the case of higher output channels the odd harmonics are above the useful band.
