CDCB ETC datasheet pdf data sheet FREE Datasheets (data sheet) search for integrated circuits (ic), semiconductors and other electronic components. The schematic as listed is shown above. The CD is responsible for FM reception, with the only datasheet I could find being in Chinese. Data Sheet INTERNATIONAL RECTIFIER IOR. T 10TQ SERIES. 10 Amp Schottky Rectifiers.

As mentioned, the instructions were all in Chinese. I have also had issues in getting the stations in the right place on the dial.
However, you might encounter some critical issues here. From here, we can mount the two copper air-coiled inductors. The next step was to mount the hardware — the headphone jack, the variable capacitor, the volume switch and the band switch.
CD , Tube CD; Röhre CD ID, IC – Integrated
Preparation Cd9088c start by first emptying all components into a plastic bowl so they can be sorted through. Assembling the AM antenna takes a little bit of work as well.
A flat bladed screwdriver helps. Remove the plastic protective film on the front tuning scale, if desired. So, I rummaged on eBay looking for radio kits, and surprisingly, there were quite a few! 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.
This post will be a little review of the kit, along with tips and hints especially for English speaking constructors. Click for more about me! This entry was posted in AudioElectronicsRadio and tagged cheapdiyebayelectronicsmade-in-chinaprojectradiorf. Two AA batteries to power the receiver. For this, stick the wire through the slot in the rear of the casing, and the screw hole end of the antenna through the slot.
Unfortunately, the instructions are only a single double-sided sheet, so the educational value of the kit is somewhat limited. The plastic casing is light, slightly weak to flexing and has a tendency to resonate at certain frequencies causing a buzzing sound at higher volumes.
For this kit, I preferred to do things the opposite way.
Do not touch the antenna or you may be burnt! Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional. The AM reception is being achieved with datsaheet CD That leaves the TDAwhich is a stereo audio amplifier chip to drive speakers and headphones. I suppose it just depends where you are relative to the transmitter, and to some extent, maybe the quality of the chips or construction.
First, slide the battery terminals into place — positive is the top terminal on the front case, negative is the lower terminal. The other two battery terminals form the positive and negative.
The reamed hole first the jack a lot better. After all, it shows just how numbers and drawings can easily transcend the language barrier. Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason. Sidecutters to cut off component legs. But at least they did provide the jack. Check the orientation of the plastic holder and the PCB slot, and glue it into place so it holds the ferrite rod parallel to the PCB.
Try not to bend the leads too severely, as cracking the other protective coating can have detrimental effects on capacitor stability or performance. Rather nicely, the PCB is a single sided paper-type board with silkscreening on both sides which is very descriptive, and solder mask on the rear.

March 23, at After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit. Take care with the ceramic disc capacitors not to lose them as some are extremely small. Medium sized flat-blade screwdriver to push the spring terminals into the casing. On catasheet of the two samples, it can occasionally during a signal dip end up getting pulled into an adjacent station over time.
Small flat-blade screwdriver to perform the variable-cap tuning procedure. Well, it took 2 months for my kit to arrive, the PCB was daatsheet, and some of the caps were illegible, but it worked on the first try. Will see if it works as well as yours did.
Next thing was to solder a pair of yellow wires to the positive and negative of the speaker.

After the fact I saw a Russian youtube vid datasheeh the SM chip being slickly soldered with two swipes of a soldering cd9088fb after he applied some flux from a pen dispenser. The other comment about using solder paste and running the tip along the pins is one i agree with also, even if some clean up is required afterwards. The radio is out of tune!
It also gives you the best access when soldering SMT parts.
Start alignment with the FM band. Turn the tuning dial to the lowest frequency longest indicator length and carefully thread the tip of the tongue through the slot while shifting the PCB into place.
