    A piece of copper would most likely shorten some of the component connectors on the underside of the circuit board. That was the main reason to use a thermal pad in the first place. This is what the documentation says, if I remember correctly.

    My UpCon6W aluminium block was getting quite hot after a few minutes into a QSO when I tried it for the first time this week. I think it went up to around 60 degrees.
