1-2 UHF Transmitter Instruction Manual UT-3 406 - 512 MHz
UHF Amplifier Instruction Manual UT-3 406 - 512 MHz : The amplifier module provides the
final stages of RF power amplification and harmonic filtering for the transmitter. This manual is
intended primarily as a reference since the amplifier module is adjusted at the factory.
Enhanced Synthesizer Instruction Manual OS(R/T)-3(A/H) 132 - 470 MHz: This manual pertains
to the enhanced synthesizer module.
UHF Transmitter Channel Designation Table UT-3 406 - 512 MHz: This document relates the
operating frequency to the transmitter channel number (see section 2.1).
1.3 UT-3 406 - 512 MHz Transmitter Family Models
There are 16 distinct models in the UT-3/400 Transmitter family each with different bands of
operation, channel spacing and/or power outputs. The 16 models are as follows:
• UT-3/420-SN02 - synthesized, 406-430 MHz band, 12.5 kHz channels, 0.5-2.0 Watt
• UT-3/420-SN08 - synthesized, 406-430 MHz band, 12.5 kHz channels, 2.0-8.0 Watt
• UT-3/420-SW02 - synthesized, 406-430 MHz band, 25 kHz channels, 0.5-2.0 Watt
• UT-3/420-SW08 - synthesized, 406-430 MHz band, 25 kHz channels, 2.0-8.0 Watt
• UT-3/460-SN02 - synthesized, 450-470 MHz band, 12.5 kHz channels, 0.5-2.0 Watt
• UT-3/460-SN08 - synthesized, 450-470 MHz band, 12.5 kHz channels, 2.0-8.0 Watt
• UT-3/460-SW02 - synthesized, 450-470 MHz band, 25 kHz channels, 0.5-2.0 Watt
• UT-3/460-SW08 - synthesized, 450-470 MHz band, 25 kHz channels, 2.0-8.0 Watt
• UT-3/480-SN02 - synthesized, 470-490 MHz band, 12.5 kHz channels, 0.5-2.0 Watt
• UT-3/480-SN08 - synthesized, 470-490 MHz band, 12.5 kHz channels, 2.0-8.0 Watt
• UT-3/480-SW02 - synthesized, 470-490 MHz band, 25 kHz channels, 0.5-2.0 Watt
• UT-3/480-SW08 - synthesized, 470-490 MHz band, 25 kHz channels, 2.0-8.0 Watt
• UT-3/500-SN02 - synthesized, 490-512 MHz band, 12.5 kHz channels, 0.5-2.0 Watt
• UT-3/500-SN08 - synthesized, 490-512 MHz band, 12.5 kHz channels, 2.0-8.0 Watt
• UT-3/500-SW02 - synthesized, 490-512 MHz band, 25 kHz channels, 0.5-2.0 Watt
• UT-3/500-SW08 - synthesized, 490-512 MHz band, 25 kHz channels, 2.0-8.0 Watt
The transmitters' band of operation is determined by select components in the synthesizer module
and the channel width is determined by the roll-off of the splatter filter on the MT-3 Audio
Processor.
