The PLL controller of the FM transmitter use SAA1057 and PIC16F628 (download HEX file). If want to change the active component, here's the list:
2SC2458 = BC547
2SA1048 = BC557
2SK192 = J310
2SB562 = BD136, BD138, BD140
2SC1923 = BF199 of BRF91 2SC1923 = BF199 or BRF91
2SC2053 = BRF96
2SB1135 = BD136, BD138, BD140
MV2105-09 = BB105, BB119
Printed Circuit Board (PCB) for this FM transmitter circuit is 155 mm x 120 mm. All coils are 0.8 mm copper wire with a 6 mm diameter. Please see parts used from schematic.
