The 5W out is at 28MHz, where the IRF510 efficiency is worse than
awful...I'll try a LM317T supply on my BITX40 and report the results. The
317T can provide up to about 1.5A.

5w out powered from an LM317 sounds fine.
And yes, the current limiting would be very handy.
20w out of the bitx40 with the irf510 at 24v would not work quite so well.

Output power after the LP filter is about 5W (+/-).
