Re: uBITX Increasing 28 Mhz output by changing C81 #ubitx-help


 

It seems like every time I try to bridge a surface mount resisitor, like I did in my search for more power, the resistor dies. ?I replaced R941, 942 and 96 last night with leaded resistors soldered to the pads, since my efforts to increase power caused a loss. ?Now I get 10W out on 80, 40 and 20, 5W on 30, 17 and 15 and 2W on 10 with a few 2n2222a's and 270pf caps added. ?If your results are poor, suspect those sneaky resistors.
