QCX Mini 20 M question about L3 windings


 

Hello All,
I have recently acquired a 40M Mini and have finished the conversion to 20 Meters .. maybe.
Original refit output was about 2.9 watts. Then removed two turns on L3 ( now at 14 T, not 16). All the windings on L1 through L4 are as evenly spread as I can make them - not bunched or crowded.
The output is now 4.7 watts, at 13.4 v supply.
My question: ?is that about it for output? Or this there more ¡°tweaking¡± I can do to reach the venerable 5 watt output??

Advice please.
Thanks
Dan VE7CTN
