# PCB AND MY PERFORM #      # IMPROVEMENTS # i1;i3 c12 and R9 for # impedance decrease intentionally # changes their values from oryginal HILAND from 10uF;47K ohm to 470nF and 1M ohm i2 added optional SMD pads for unpolarised 10uF cappacitor This improvements gave better range width to small cappacitors measure, which will be show on the picture.   # IMPORTANT MODIFICATIONS # M7 instead 1800 pF cappacitor replaced to 1377 pF - THIS CHANGE MUST BE OVERWRITE INTO THE PROGRAM REFERENTIAL CAPPACITANCE VALUE (2 BYTES CHANGE) M8 R5,R6 instead 2000 ohm and 200 ohm mounted 2213 and 219 ohm - THIS CHANGE MUST BE OVERWRITE INTO THE PROGRAM REFERENTIAL RES. VALUES (4 BYTES CHANGE)  # OTHER NOT IMPORTANT MODIFICATIONS # M1 - r14,r15 instead 5k1 res used 4k7 - doesn't matter M2 - Instead 9012 used BC557 (DIFFERENT FOOTPRINT!) M3 - 8050 replaced to BC547 (DIFFERENT FOOTPRINT!) M4 - 4148 diodes replaced to any diode to pretect before over voltage peak M5 - inductance 82 uH replaced by 68uH - just change resonance to higher freq. M6 - c9 1800 pF replaced to 1000pF - the resonant circuit going to higher freq.  # IMPROVEMENTS # **i1;i3 c12 and R9 for impedance decrease intentionally changes their values from oryginal HILAND from 10uF;47K ohm to 470nF and 1M ohm i2 added optional SMD pads for unpolarised 10uF cappacitor This improvements gave better range width to small cappacitors measure, which will be show on the picture.** # IMPORTANT MODIFICATIONS # M7 instead 1800 pF cappacitor replaced to 1377 pF - THIS CHANGE MUST BE OVERWRITE INTO THE PROGRAM REFERENTIAL CAPPACITANCE VALUE (2 BYTES CHANGE) M8 R5,R6 instead 2000 ohm and 200 ohm mounted 2213 and 219 ohm - THIS CHANGE MUST BE OVERWRITE INTO THE PROGRAM REFERENTIAL RES.
