Note the orientation, unbend the pins, insert cd9088cg solder away. Take note of the orientation, insert, bend leads, solder and clip leads until all the electrolytics are mounted. 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.
Ordering two ensures that you have some spares in case things do go wrong …. Proudly powered by WordPress. September 12, at 3: Samples of the audio as recorded by my Zoom H1 dtaasheet are here.
I have achieved everything, except the connections of the AA Batteries.
Then secure this with the other identical machine screw. March 23, at Take care with the ceramic disc capacitors not to lose them as some are extremely small. Next, obtain the larger tuning dial and align the indentation.
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. Use the slightly different machine screw to secure the antenna to the rear casing. This might be the case especially near the headphone jack.
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 values can either be read or checked with a meter. Align the switch and use one of the two identical machine screws to fasten.
Getting to this stage takes about an hour. Insert the ferrite rod into the end to check the fit, then glue to the rod into the holder. Everything is in Chinese. November 10, at 3: At this stage, we are ready to make the final connections and assemble the unit. First, slide the battery terminals into place — positive is the top terminal on the front case, dc9088cb is the lower terminal. Conclusion After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit.

I did have problems with the jack but cr9088cb it misaligned. I actually tried this on my second kit and it was a disaster. Once that is soldered into place, you can breathe a sigh of relief as the worst part is over. 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.
Then solder each successive pin taking care not to short out adjacent pins. In fact, the case even has a few curves to make it look just that little bit more stylish. Start by identifying pin 1 and straightening bent pins. For this kit, I preferred to do things the opposite way.
Next thing was to solder a pair of yellow wires to the positive and negative of cf9088cb speaker. My board looks like this — cd9088db for the population of resistors. Magnifying glass and light to read small component values and markings also optional. A capacitor is hence a 10 pF capacitor, or 0.
So, I rummaged on eBay looking for radio kits, and surprisingly, there were quite a dafasheet Hi, I have had made it 3 times, and the last was today. The final connection is the FM antenna connection.
Sound quality is good. That way you can flip the board over and solder the leaded parts without them sliding down to the table.

I agree about the SMD Hot air re-flowing. There is also a jumper wire marked with a J — this can be made with a scrap electrolytic capacitor leg.
Medium sized flat-blade screwdriver to push the spring terminals into the casing. The AM reception is as per most TRF receivers — not particularly high quality and it datwsheet that this is prone to overload.
Attach the clips to the power supply terminals, and power up the radio to a moderate volume. If I was doing this again, as I did for my second kit, I would populate the resistors before the capacitors mainly because the clearance to datashee resistors flush on the board is limited once the capacitors are installed.
The other two battery terminals form the positive and negative. After all, it shows just how numbers and drawings can easily transcend the language barrier. 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.
