If you are talking about an electromagnetic wave, it will travel a light-year per year. That's how the "light-year" is defined. The frequency (1400 MHz) is irrelevant in this case.
Traveling 39 light years would take 39 years at the speed of light.
Traveling 40 light years would take 40 years at the speed of light.
It would take approximately 65 years to travel at the speed of light from Earth to Aldebaran, which is about 65 light-years away. However, currently, we do not have the technology to travel at the speed of light.
Traveling 40 light years would take 40 years at the speed of light.
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.

Like any distance, it depends on how fast you are going. At the speed of light it would take 4,000 years to travel that distance.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
If you are asking how long it would take to travel the distance of 123.23 light years, then that would depend on how fast you are traveling. Because a light year is a measure of distance not time.
A light year is a measure of distance not time. A light year is the distance light travels in one year. So for light to travel 6,300 light years, would take 6,300 years
