CDCB Datasheet – Monolithic electric tuning FM radio IC
Take note of the orientation, insert, bend leads, solder and clip leads until all the electrolytics are mounted. Just another way engineering solves the day! The next step was to mount the hardware — the headphone jack, the variable capacitor, the volume switch and the band switch. Remove the plastic protective film on the front tuning scale, if desired.
Rather nicely, the PCB is a single sided paper-type board with silkscreening on both sides which is very datashdet, and solder mask on the rear. Use the slightly different machine screw to secure the antenna to the rear casing. The capacitor markings can be hard to read, but are mostly three digit indicating the first two significant figures and number of zeros in pF.

The reamed hole first the jack a lot better. The educational value, however, is a little limited cd9088ch explanations.
It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in. Would have liked the legs on the FM chip a bit longer, would have been even better if chips had fitted into DIL sockets.
Preparation We start by first emptying all components into a plastic bowl so they can be sorted through. Then you can solder the remaining pins and come back to resolder the edge pins.
Click for more about me! About one to two hours of time to complete the kit. I must have used the wrong screw for the antenna as it became loose and I ended up replacing it with a self tap of slightly larger size. Start by identifying pin 1 and straightening bent pins. It seems to have a lacquer finish to stop the pads from oxidising, but is not otherwise tinned nor plated. At this stage, we are ready to make the final connections and assemble the unit.

Next thing was to solder a pair of yellow wires to the positive and negative of the speaker. Getting to this stage takes about an hour. Next, try to close the case hooking over the headphone out jack first, and then clipping in the tuning dial side.
January 17, at 3: Superglue is not preferable because it cracks when the datasjeet is flexed, but should still work somewhat adequately. It also gives you the best access when soldering SMT parts.
dataheet January 17, at 5: Will see if it works as well as yours did. Keep the terminals loose on your bench and solder a red wire to the positive and black wire to the negative. Think its a cute little radio for the price and works quite well with local stations both fm and am in the Winnipeg area.
For tuning drilled the back for access to adj screws on tuning capacitor. The schematic as listed is shown above. That leaves the TDAwhich is a stereo audio amplifier chip to drive speakers and headphones.
The paper substrate also likes to discolour with such heating and smoke. As a result, I accepted the challenge and put in an order for two kits.
Sound quality is good. On one of the two samples, it can occasionally during a signal dip end up getting pulled into an adjacent station over time. Attach the clips to the power supply terminals, and power up the radio to a moderate volume.
We start by first emptying all components into a plastic bowl so they can be sorted through. Well, it took 2 months for my kit to arrive, the PCB was bowed, and some of the caps were illegible, but it worked dataseet the first try. As an experienced kit builder, I wasted no time in getting started.
April 25, at Because there were more capacitors, I decided to tackle them first.
CD9088CB Datasheet PDF – FORWARD
Trouble was already spotted when a loose screw was seen ccd9088cb inside the bubble wrap — the components have broken loose and the only thing preventing them from going everywhere was a thin and somewhat torn bubble wrap. In my case, I ended up substituting a salvaged from another piece of broken equipment … but this is why having two kits with the intention of making just one might be useful. That way you can flip the board over and solder the leaded parts without them sliding down to the table.
Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional. Do not fit them into the casing until they are cool, otherwise you will melt the plastic casing! Insert the ferrite rod into the end to check the fit, then glue to ccd9088cb rod into the holder.
From here, we can mount the two copper air-coiled inductors. Repeat for the UTC as well. First, slide the battery terminals into place — positive is the top terminal on the front case, negative is the lower terminal. Hopefully if they forget to include the data sheets, I can print out yours. But at least they did provide the jack. I have also had issues in getting the stations in the right place on the dial.
