Finished my QCX mini build (20m) about a week ago and was only getting about 1.38 watts out of it so I decided to try Hans's tune up video from 4 years ago.? I took out 2 turns from L3 and then played with the winds on L1 thru L3 and was able to increase the output to 2.05 watts.? While adjusting the turns on L2 I noticed the first/last turn was crossed with the adjacent wind so I desoldered and removed the cross and its turn, then started adjusting winds to see if the power came up.? Well, the power out came up to 2.5 watts, but while I was fidgeting with the turns the power dropped to 0 watts and smoke erupted from ic TI37A2QDM/CBT3253C.? What did I do wrong?? I am not skilled enough to change the 16 pin IC so I'll probably just have to chock it up as a poor decision to play with the winds, although, did having the cross in L2 cause my low power out in the first place?? Any advice would be appreciated.
