Regardless of which band or mode chosen in the band selected, with antenna and/or microphone and/or earphones connected or not, powered by 12v battery, when I turn on my 7000, the red TX light is always on. When last I turned it off, it was working well. All I did was move it to a different location. Any ideas, troubleshooting tips or suggestions would be very much appreciated. Thank you. Gus, NU4L.
