Here's PLL FM transmitter circuit from china. This circuit uses the familiar 2SC1971 for final power amplifier stage. 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.
