Re: How to reduce uBITX output power?

Adjusting RV1 is the best way to reduce power.
You might also go to a bigger heatsink someday, but note that the IRF510 tabs are at 12 volts
so be careful you don't ground them.  Tom's fan is also a good idea.
You do not want the IRF510's getting so hot you can't hold your finger on them.
