Capabilities
Power
The VX3 to VX6 transmitters are solid-state, VHF, frequency modulated broadcast transmitters. See
Table 1.1.1 for continuous RF output power capability, noting the maximum VSWR limitations for rated
and maximum power.
Table 1.1.1: VX3 to VX6 Power Capability
The operator can vary the power continuously or switch to preset power levels using the transmitter’s
remote advanced user interface (AUI) or the front panel user interface (FPUI).
Frequency
The VX3 to VX6 transmitter is broadband and can operate at any frequency in the FM broadcast band
(87.5 - 108 MHz), into a nominal 50 ohm, unbalanced transmission line.
Antenna Tolerance
The VX3 to VX6 transmitter will operate at rated power even with a VSWR of 1.5:1. A higher VSWR
results in a protective foldback of output power. The greater the VSWR, the greater the reduction in RF
power until shutdown occurs at 3:1 VSWR.
