What to do if my RF Power HVLA1K3 PLUS Amplifier shows fault lights?
If the fault lights are on, it could be due to a high antenna VSWR. Check the integrity of your antenna and feedline connections, and ensure the antenna is resonant at the desired frequency. Alternatively, the wrong band may be set. Ensure you match the band correctly.
Why can't I enter transmit mode on my RF Power HVLA1K3 PLUS Amplifier?
If you're unable to enter transmit mode, it might be due to the control cable not being properly connected; check the control cable and connect it correctly. Another possibility is that the protection circuits are active. In this case, check the drive power, antenna VSWR, whether the wrong band is selected, the antenna selector A or B, or if there's a high temperature issue. Reset the amplifier using the AC power switch.
What to do if my RF Power Amplifier is overheating?
If your amplifier is overheating, ensure adequate airflow around the unit and keep the cooling fins unobstructed. Also, check the VSWR of the antenna system, as a high VSWR increases heat dissipation. Reduce the drive level or duty cycle.
How to fix TVI, EMI issues with my RF Power HVLA1K3 PLUS Amplifier?
To address TVI or EMI issues, first decrease the drive, as RF overdrive can be a cause. Also, RF leakage from the coax cable, grounding wire, or AC power cord could be the culprit. Try inserting common mode filters on the antenna cable or AC line, and add clamps on ferrite cores on various cables.
What to do if my RF Power Amplifier shows over drive lights?
If the overdrive lights are illuminated, it indicates RF overdrive. Decrease the drive to resolve this issue.
What to do if AC mains not operating in my RF Power HVLA1K3 PLUS Amplifier?
If the AC mains are not operating, it could be due to blown AC fuses; replace them with new ones. Another possibility is that the AC cord is not plugged in securely; ensure it is properly plugged in.
