Transmisor de FM sintetizado con PLL

Capacitores

C1,C2 - 47pf or 20pf ceramic disc (match to 4.00Mhz crystal load imp)
C7,C8,C15,C23,C24, - 0.01uf ceramic disc
C10,C12-C14,C16,C22,C26-C29,C31 - 0.001uf ceramic disc Y5P temp coeff
(note, on the FM100, C16 = 0.1uf ceramic disc for better bass. Must change R10 also.)
C18,C20 - 8.2pf ceramic disc (10pf will work fine too! get COG temp coef version)
C33 - 220pf ceramic disc
C9 - 0.1uf ceramic disc

C3,C4,C6,C17,C19,C21,C25,C34 - 10uf 35V electrolytic (anything above 16V is ok)
C5, C11 - 1000uf 35V electrolytic cap (C11 may be 470uf)

Xtales

Y1 - 4.000Mhz PARALLEL CUT CRYSTAL (Important! Use a parallel NOT series crystal)
Y2 - 38Khz cystal (available from Digi_key)

Bobinas 

(only one since there is no low pass filter!!)

L1 - 0.085 - 0.100uH adjustable shielded can tunable coil (Mouser part
number 434-1012-3.5CS)

Resistencias  

all are 1/4W 5% carbon film types

R1,R2,R4,R8,R18,R20,R23-26 - 10K
R2 - 470 ohm
R3 - 1Meg (10Meg can be used too)
R5,R13,R14,R17 - 270 ohm
R7 - 100K
R9,R15 - 68K for US (or 150K), don't know yet for Europe/Asia. Used for Pre-emphasis.
R19 - 2.2K (this resistor sets the non-boosted mode power.)
R10 - 1K (470 ohms is used on the FM100, but must change C16 also)
R12 - 100 ohms
R21 - 4.7K
