Is it Legal to Solder the power cord to the D-Link

[StealthMentor]

It is the new radio for this year, we are using the included connector, it has done this since the first time we powered it up. One strip of electrical tape helped, but it would still happen. A lot of duck tape helped more, but it would still happen every once in a while. I am thinking that the solder connections were bad out of the box.

I am thinking about swapping it out for last years and see if the problem still occurs. I saw someone post about isolating the power converter, ours is attached to the frame, we assumed that since it was a big heat sink this would help keep it cool. Is isolating this from the frame really necessary? I did not see this in the rules. We might give it a shot anyway to see if it helps.

Thanks!
