February 5, at 7: For this kit, I preferred to do things the opposite way. November 24, at 8: Start alignment with the FM band.

The best rule of thumb when assembling circuit boards is to start with the lowest height components and progress to the tallest ones. Just another way engineering solves the day! April 25, at This might be the case especially near the headphone jack. Otherwise, the IC may not be soldered in the dataxheet orientation, or the switch may have been damaged.

Maybe one radio station at the most. The educational value, however, is a little limited without explanations. Insert your two AA batteries of choice, and you can start listening to radio right away.

Because there were more capacitors, I decided to tackle them first. Dd9088 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. The radio is out of tune!


Cool kit and fun to build. Of interest is that the reception mode switch actually switches the audio path to the amplifier. 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.

Once it is soldered, the speaker can be glued into the front casing with hot melt glue around the edge or superglue if unavailable. Rather unimpressively, each kit comes in a bubble wrap package. Then solder each successive pin taking care not to short out xatasheet pins.

Start by identifying pin 1 and straightening bent pins. Datasehet care with the ceramic disc capacitors not to lose them as some are extremely small. Part of the ce9088 seems to be the jack itself being slightly larger than the hole in the rear plastic cover — reaming out the hole slightly using a large Philips head screwdriver seems to do the trick. November 10, at 6: Now, the screws need to be sorted and the dials installed.

It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in.

I enjoyed a lot this kit. Note the orientation, unbend the pins, insert and solder away. Try not to bend the leads too severely, as cracking the other protective coating can have detrimental effects on capacitor stability or performance. Kit Contents Rather unimpressively, each kit comes in a bubble wrap package.

This post datasehet be a little review of the kit, along with tips and hints especially for English speaking constructors. March 23, at Everything is in Chinese.


Frank McCaffery Dec 20 Assembled without too much trouble. Filtering is achieved with the external components — mainly R-C filters.

The hiss swamps out the signal at low volumes which are comfortable for listening in a quiet room … which is disappointing. March 23, at 9: You might get static, or nothing. I actually tried this on my second kit and it was a dattasheet.

Next, solder the speaker wires with both yellow wires going to one SP terminal respectively. After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit. January 17, at 5: The FM antenna also needs to have a wire connected to it.

First, obtain the smaller volume dial and check the indentation for the rectangular brass stud of the switch. I suppose it just depends where you are relative to the transmitter, and to some extent, maybe the quality of the chips or construction. Attach the clips to the power supply terminals, and power up the radio to a moderate volume. Another radio that is in tune to verify received stations also recommended, but not absolutely necessary.

Use the slightly different machine screw to secure the antenna to the rear casing.
