FDA24N40F... Apparently this is the real part number of the restamped ERF9530.
Well I intend to order one and find out.

It's all about the speed. Since these parts are characterized to function as switches, the on/off delay times are your only guide to the max RF frequency it will amplify.
Here's the delay times for the IRF520.
And here's the FDA24N40F:
The FDA part is at least four times as slow as the IRF520. Looks like you won't get any real RF gain much above 7 or 8 MHz.
Then again, don't let me discourage you from trying. I'll predict that your power gain from input to output won't be much more than about twice the drive power.
Only one way to be sure.
Oh, and about that "gentleman's agreement" thing? Just remember the math. Two men can keep a secret if one of them is dead. My personal incentive is to spread knowledge, not conceal it.
