I had 1.86W at 12.0 volts. Removed 1 turn each from coils L1, L2, L3. Increase output to 2.12 W, not a great change.?Measured loss prior to change was -2.29 dB through the filter at 14.020 MHz.
May replace capacitors next. Don't really mind 2 W since its QRP and 5 is too much, but can't let well enough alone.
