How to reduce uBITX output power?

Hi, 

I have had success with the WSPR beacon mode using Dr. Lee's uBITX firmware. On each WSPR band, I matched my antenna for low SWR as best as I could. On some bands, the finals get VERY HOT so I would kill power to the uBITX hopefully before I destroyed the finals. I do realize that digital transmission modes are high duty cycle loads. 

In an attempt to reduce output the uBITX RF power, I turned RV1 clockwise 1/8 turn to reduce output power on the finals - that helped prevent overheating. 

Is adjusting RV1 the best way to reduce output power with a stock uBITX build?
