I did have problems with the jack but left it misaligned. Frank McCaffery Dec 20 Assembled without too much trouble. So, I rummaged on eBay looking for radio kits, and surprisingly, there were quite a few!

The reamed hole first the jack a lot better. About one to two hours of time to complete the kit. I have found the AM section to be very un-selective.

Note the temptation to use hot-air reflow techniques. On one of the dahasheet samples, it can occasionally during a signal dip end up getting pulled into an adjacent station over time. I found the top of the FM band hard to reach, but not impossible with a combination of spreading the coils and adjusting the offset trim on the variable capacitor itself.

Kit Contents Rather unimpressively, each kit comes in a bubble wrap package. March 23, at 9: Do not fit them into the casing until they are cool, otherwise you will melt the plastic casing! As a result, I accepted the challenge and put in an order for two kits.

After that, actually getting any practical usage out of it would be pretty c9088 a bonus.

Next, solder the speaker wires with both yellow wires going to one SP terminal respectively. This entry was posted in Audio datqsheet, ElectronicsRadio and tagged cheapdiyebayelectronicsmade-in-chinaprojectradiorf.

Take care with the ceramic datwsheet capacitors not to lose them as some are extremely small. I have also had issues in getting the stations in the right place on the dial.

September 8, at 1: The unit has an IF datasbeet about 70kHz, and features a frequency locked loop with internal muting of weak signals. Get good reception aroun Mhz with correct pointer position. September 12, at 3: Repeat for the UTC as well.

Instead, you will have to solder the yellow wire to the arm next to the screw cd908, making sure the solder is low profile not to interfere with fitting the antenna through the slot.

January 25, at 1: In fact, the case even has a few curves to make it look just that little bit more stylish. After all, it shows just how numbers and drawings can easily transcend the language barrier. It also gives you the best access when soldering SMT parts.

Now, the screws need to be sorted and the dials installed. Luckily for everyone, the board also has very good silkscreening to judge by the listing. The FM antenna also needs to have a wire connected to it. 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.

Note the orientation, unbend the pins, insert and solder away. Part of the cause 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.


Superglue is not preferable because it cracks when the case is flexed, but should still work somewhat adequately. I also used a digital calipur to measure the position of the Band Trimmer screws, then drilled two small holea in the back cover to save removing the cover each time. Hi, I have had made it 3 times, and the last was today.

I actually tried this on my second kit and it was a disaster. Use the slightly different machine screw to secure the antenna to the rear casing. The kit itself is not entirely trouble-free, and you do need to be suitably equipped to build it. Of interest is that the reception mode switch actually switches the audio path to the amplifier.

You can remove the self-adhesive backing from the front window and apply it to the front of the casing, checking the orientation. Assembling the AM antenna takes a little bit of work as well.

Lead the yellow wire to the ANT terminal and tack solder. This really is a kit that looks almost store bought!
