Ok,I have done two 29's with the erf2030 mod, both radios have a good dk but i cant hit the 40 watt mark. All i seem to get is 30 or less. Anybody have an idea of what resistor or cap i need to remove to hit the 40 watt mark or settle for what i am getting and be happy. Both radios sound good when getting outside radio checks. Thank you for yuor help and information
 

The ERF2030 is only a 25 watt transistor. I think you're doing really well to get 30 watts out of it. About 28 watts is all I've ever gotten out of them.

I agree, your radio is working just fine with that mod. To see more watts (which won't matter anyway) you will probably have to get a true peak reading meter, run into a dummy load, and bump up the voltage on your power supply to 14.8. After that some tune and alignment work will be needed. In the end what will that accomplish?
