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.

You can remove the self-adhesive backing from the front window and apply it to the datashee of the casing, checking the orientation. One time I even reduced the turns on one of the coils. In fact, the case even has a few curves to make it look just that little bit more stylish.
I was aware of the Tecsun 2P3 which looks to be a very nice kit, but a bit on the pricey side for an AM only radio. Continuing on, the board is completed with the population dc9088cb resistors. February 5, at 7: The unit has an IF of about 70kHz, and features a frequency locked loop with internal muting of weak signals.

Ordering two ensures that you have some datashee in case things do go wrong …. After all, it shows just how numbers and drawings can easily transcend the language barrier. Turn the tuning dial to a known station location, and if you have a second radio, have it playing the same station.
For this kit, I preferred to do things the opposite way. However, you might encounter some critical issues here.
I also used a digital calipur to measure the cf9088cb of the Band Trimmer screws, then drilled two small holea in the back cover to save removing the cover each time. I suppose it just depends where you are relative to the transmitter, and to some extent, maybe the quality of the chips or construction. April 25, at The other two battery terminals form the positive and negative. Luckily for everyone, the board also has very good silkscreening to judge by the listing.
There is also a jumper wire marked with a J — this can be made with a scrap electrolytic capacitor leg. Take note of the orientation, insert, bend leads, solder and clip leads until darasheet the electrolytics are mounted. Once roughly in place, you can take the AM-FM mode switch, deburr the plastic and push it through the exterior casing over the switch. I enjoyed a lot this kit. Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason.
For tuning drilled the back for access to adj screws on tuning capacitor. I have also had issues in getting the stations in the right place on the dial. Small flat-blade screwdriver to perform the variable-cap tuning procedure.
Bench-top supply with crocodile clips, 3V output to power receiver during tuning recommended, but not absolutely necessary.
Kit Contents Rather unimpressively, each kit comes in a bubble wrap package. This might be the case especially near the headphone jack. The AM rod antenna connections can be made by looping out the enamelled wire over the top of the PCB is best and tack soldering the ends to AM terminals. For speaker used twisted pair.
January 17, at 5: Align the switch and use one of the two identical machine screws to fasten. Cd9088ch radio that is in tune to verify received stations also recommended, but not absolutely necessary.

We start by first emptying all components into a xatasheet bowl so they can be sorted through. Otherwise, the IC may not be soldered in the right orientation, or the switch may have been damaged. Assembling the AM antenna takes a little bit of work as well. June 15, at Frank McCaffery Dec 20 Assembled without too much trouble. As an experienced kit builder, Dataxheet wasted no time in getting started.
Then secure this with the other identical machine screw. Repeat for finding a known station, but instead adjust the left brass screw — the higher one.
I must catasheet 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. It is used to drive the headphone jack which disconnects the internal speaker once a datasyeet plug is plugged in. Proudly powered by WordPress. February 5, at 5: Well, it took 2 months for my kit to arrive, the PCB was bowed, and some of the caps were illegible, but it worked on the first try.
Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio Kit
Get good reception aroun Mhz with correct pointer position. 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. The reamed hole first the jack a lot better. Samples of the audio as recorded by my Zoom H1 recorder are ce9088cb. You might get static, or nothing.
