300 mWatts FM broadcast transmitter (87,5-108 MHz), 50kHz stepsize, dual-speed. (Hartley oscillator version) All component values are drawn on the .comp and .silklayer bitmaps, with the following exceptions; 1.- mount a 10pF (1206 SMD-chip capacitor) between the base and collector of BC547 (this is the 'switch' transistor in the loopfilter section). 2.- L1 = 4.5 turns, 6 mm diameter, 1 mm CuAg, tap ¾ to 1 turn from ground (spaced) 3.- Cx = 3n9 (50µS) or 4n7 (75µS) 4.- JP1 = 2 pins header + jumper 5.- all 1uH and 0,1uH coils are ready-made molded type coils. Notes (*) not used CuAg = silver plated copper wire CuL = magnetwire, enameled copper wire (Note: 1 mm CuL approx. equals to AWG18 0,3 mm approx. equals to AWG28) (I) all diameters are measured from the inside of the coils The green led indicates if the PLL is locked The red led indicates if the PLL is not locked (C)2005 Helix Inc. The Netherlands.
Microchip PIC16F628(A) control software Frequency range : 87.5-108MHz Stepsize : 50kHz (Up/Down) Feature(s) : scans faster in 'Set' mode through the frequency range when either the 'Up' or 'Down' button is pressed for more then 3 seconds. pressing the 'Up' or 'Down' button when the PLL is locked, switches the backlight of the lcd 'on' or 'off'.
Nah
yang ini baru ciamik....PLL FM Display LCD. Bisa tau frekuensi yg
sedang on air. Pemancar Fm PLL LCD disainnya cukup sederhana daripada
PLL Veronica. Hanya menggunakan IC TSA 5511 sbg prescalernya atau pllnya
dan IC PIC 16F84 sebagai mikrokontroller pengendali LCD. Transistor
bagian depan dari oscilator sampai driver PLL ini menggunakan jenis FET
dan transistor rf powernya menggunakan 2SC1971. Dan dilengkapi dgn LPF (
Low Pass Filter ). Setting frekuensinya hanya dengan tekan tombol
menu/set, selanjutnya tekan tombol up-down utk menentukan frekuensi yg
di inginkan. Benar-benar simpel dan praktis di banding PLL Veronica yg
masih manual pake dip switch dan tune VFO-nya. Untuk menjalankan program
PIC 16F84 harus melalui proses writer atau memprogram dgn HEX Code.
Harus ada programmer/downloader varian ic PIC.
