OK, well...some...education.
Your radio is not a constant power device. That is not a DCDC converter with a load, where you increase the voltage and the current drops proportionally.
It is a linear load, more or less, so your power rises as the square of your voltage.
That is it will be 146W.
And your current will be 146:122 = 1.2A.
Now, if this your operating current, considering the radios pull some inrush on the power-up, I would use 200% slow-blow fuse.
That is 2A to 2.5A slow blow would be my choice.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
