- Page 3 C-6204 Operation of the electronic circuit This radio has SC1088 or TDA7088T integrated circuit, which is used by manufacturers of portable radios. This integrated circuit contains all the basic components required for the construction of a radio. Includes a frequency locked loop (PLL), intermediate frequency (IF) centered at 70 kHz, modulator block, etc.
- Page 4 C-6204 Basic outline of the chip, the FM radio tuning by scanning application. Each technician applies the necessary changes to your application. Therefore the component values are merely indicative and may vary according to each of the applications. FM receiver with SCANNER SEARCH scheme Take the output signal in the number of integrated circuit pin 2 (HFOV).

- Page 6 C-6204 Placement of components on the printed circuit Note that the integrated ASIC, being the type SMD (surface mount) and delicate welding circuit is already soldered on the printed circuit board. The normal welding of a printed circuit is a simple process.
- Page 7 C-6204 Mounting tabs : E10, E20, E30 y E40 Mounting resistors Tools : Welder, tin, tweezers or needlenose pliers and cutters 1. The resistors have no polarity. We check the value according to the color code: R1 - 560 Ohm - green, blue, brown R2 - 220 k Ohm - Red, red, yellow R3 - 1.5 k Ohm - brown, green, red...
- Page 8 C-6204 Mounting coils L1 and L2 Tools: Welder, tin, tweezers or needlenose pliers and cutters 1. We will place the coils L1 and L2. The coil L1 is the smallest. The welding must be done in the tinned part of the leg, not the glazed part.
- Page 9 C-6204 Mounting tabs : E50, E60, E70, E80, E90 y E100 VARICAP diode assembly Tools : Welder, tin, tweezers or needlenose pliers and cutters 1. We will place the varicap diode. NOTE: POLARIZED COMPONENT. It has a completely flat face with the screen and the other side with two chamfers.
- Page 10 C-6204 Mounting electrolytic capacitors Tools: Welder, tin, tweezers or needlenose pliers and cutters 1. We will place electrolytic capacitors NOTE: COMPONENT POLARIZED Cut and strip square White = NEGATIVE 2. will put in place and we will open the pins from falling when turning the circuit.
- Page 11 C-6204 L3 coil assembly Tools : Welder, tin, tweezers or needlenose pliers and cutters 1. We will insert one of the legs of the L3 coil in the lower bore the circuit marked "30P" 2. solder pin inserted into the circuit board.
- Page 12 C-6204 battery holder assembly Tools: file small middle-cane 1. Check the battery well. We need 2 R6 / AA batteries. 2. We will place the batteries, as is marked box (see Figure A) and post the cover. 3.Sacaremos the cover. The two batteries should easily leave the docks of the base of the battery compartment.
- Page 13 C-6204 Mounting tabs : E300 Mounting buttons Tools: Screwdriver small star 1. Carefully turn the potentiometer until close (to note the "click" and the movement of the switch is on the side of the components). 2. Place the potentiometer knob with numbers down.
