DE DANIELSELECTRONICS2 VT-3H040 VHF Enhanced Transmitter Instruction ManualVT-3H040 VHF Amplifier: The amplifier module provides the final stages of RF poweramplification and harmonic filtering for the transmitter. This manual is intended primarily as areference since the amplifier module is adjusted at the factory.OS-3H040 Synthesizer: This manual pertains to the synthesizer module. Channel selection isdescribed in the 'Transmitter Main Board' Manual.VT-3H040 Channel Designation Table: This document relates operating frequency to thetransmitter channel number (see section 2.1).1.3 VT-3H040 Transmitter Family ModelsThe VT-3H040 line of transmitters has a single RF power output rating of 3.0 Watt, with wideband FM (20 kHz or 25 kHz channels) and employs synthesizer based frequency generation. Thetwo basic (i.e. no options added) band specific models of the transmitter are as follows:VT-3H035-SWA3: 29 MHz to 38 MHzVT-3H045-SWA3 38 MHz to 50 MHzThe frequency is determined by the model of synthesizer and by the lowpass filter that isinstalled in the amplifier module (see the VT-3H040 VHF Amplifier manual for details). Agroup of channels spanning 38 MHz can be accomodated by one of the models providing that thefrequency span does not exceed 1.0 MHz. Model VT-3H035-SWA3 can operate at frequenciesup to 38.5 MHz and is the preferred choice when spanning 38 MHz. Consult the factory forfuther information regarding operation around this frequency.
