Satellite Reciever Board grade?

That's true enough.

One would think that low grade power supply boards would have more copper per pound but very little in the way of precious metals.

I suppose the math would be different for every kind of board that you're looking to refine.

In just the board itself the average is about the same. But the transformers, heatsinks, big capacitors, steel and such dominate the weight and reduce the /lb copper recovery.
