NOTES:
1. Selecting 18, 22, or 27 pf for C18; establishes the FM-band fre-
quency adjustment range. See "Choosing an Operating Fre-
quency."
2. Selecting 180K, 220K, or 470K pf for R8; establishes the stereo pilot
level for the desired FM-band frequency to be used. See "Choosing
an Operating Frequency."
3. R5 and R6 set the pre-emphasis of the transmitter. For 75 uS (USA)
use 15K ohm resistors. For 50uS (Europe) use 10K ohm resistors.
