Re: boosting the power on 28 MHz #ubitx


 

Hi, is the 330pf across the PA transformer mod all what is needed to get reasonable output (5w) on 28mhz or should I also make the Farhan mods ( Replace C81 from 0.1uf to 470pf Replace R83 from 10 ohms to 2.2 ohm (you can short R83 as well) Replace R97, R98 from 47 ohms to 220 ohms Remove C261, C262)? Should I also change R63? Should I reduce drive via RV1? 73 Franco

Since it's always nice to have someone doublecheck your work, would this be the proper place to add the cap if you mount it on top of the board?
