10. The TAUD-40 LCD shows the user the present status of the amplifiers. Adjust RF output power to
desired level (see Important RF Power Notice in previous section). Verify that the FWD Power
reads 100% or less - depending on signal content. The output power level can be adjusted using
the modulator or processor’s RF output level adjust. Keep in mind that the system will shut down
should the forward RF output power level be exceeded.
11. Ideally, the RFL Power should read zero. However, should a high VSWR be detected, the system
will automatically shut down and cycle as previously described. This is also shown as a percentage
of rated forward power.
12. Verify that the power supply reads approximately 30 Volts DC (see supplied final inspection sheet
for factory settings of power supply levels) on the LCD of the power amplifier.
13. Look at the transmitted output using a suitable monitor. If the signal quality is unsatisfactory, check
the input signals, connections to the antenna system, antenna and transmission line VSWR, and
the physical condition of the antenna.
If reception problems are encountered, and the quality of transmission is satisfactory, the difficulty is
often with the receiving antenna or with obstructions in the path between the transmitter/translator and
receiver.
