Tuner Genius XL Issues

Dr. T

My Tuner Genius XL has worked perfectly since installation. However, when broadcasting on any band after about 30 seconds, the Tuner Genius XL screens suddenly displays red and indicates SWR >10.1. I have retuned several times, obtaining an SWR of 1.1:1 only to have the window and warning reappear. I tried to reset the unit following p. 64 of the manual, however when pressing and holding the BYPASS/OPERATE button while turning the unit on does not give me the "Config Reset" message.

I would start by checking with low power operation. 5 watts. See if it happens.

if it only happens under high power then possibly something in your feed line or antenna system. Test under high power into a dummy load that can handle high power for longer key down time.

Years ago I had a G5RV antenna which used solid conductor 450 Ohm ladder line. From the wind, the conductor had a break in one leg of the ladder line but the plastic coating was intact so you could not see the problem. It was fine under lower power but would cause arcing and high SWR at legal limit.

All antennas connections are good. The problem also occurs when changing from the vertical the dipole. The reset options on p. 64 of the manual does not work. It seems all indicators point to the problem with Tuner Genius.

Open a Help Desk ticket then.
