The IRFz24 might be made to work well at 7mhz,?but is not a drop in replacement on the uBitx.
Be prepared to give it significantly more drive, especially if you hope to run it at 30mhz.
Total gate charge of the IRF510 is 8.3nC
Total gate charge of the IRFz24 is 25nC
The IRF510 is hard to beat as a cheap NFET for an HF amp.
