For this kit, I preferred to do things the opposite way.
Attach the clips to the power supply terminals, datasheett power up the radio to a moderate volume. The FM antenna also needs to have a wire connected to it. Repeat for the UTC as well. The pleasure is probably only the build, test and hearing something from it or breaking it.
In the case of this kit, this specifically includes: Think its a cute little radio for the price and works quite well with local stations both fm and am in the Winnipeg area. Start alignment with the FM band.

I agree about the SMD Hot air re-flowing. Lead the yellow wire to the ANT terminal and tack solder. As a result, I accepted the challenge and put in an order for two kits. 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 get resistors flush on the board is limited once the capacitors are installed. You might get static, or nothing.
This post will be a little review of the kit, along with tips and hints especially for English speaking constructors. I have found the AM section to be very un-selective.
At this stage, I decided to mount the electrolytic capacitors, since there were only a few of them and their values are easy to read. Getting to this stage takes about an hour. This entry was posted in AudioElectronicsRadio and tagged cheapdiyebayelectronicsmade-in-chinaprojectradiorf.
Unfortunately, the instructions are only a single double-sided sheet, so the datahseet value of the kit is somewhat limited. Hot melt glue, or superglue to stick the speaker, ferrite rod antennas darasheet place.
I wonder if adding some holes in the back of the case would help. The final connection is the FM antenna connection. The next step is to align the AM band.
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.

Superglue is not preferable because it cracks when the case is flexed, but should still work somewhat adequately. The capacitor markings can be hard to read, but are mostly three adtasheet indicating the first two significant figures and number of zeros in pF.
Proudly powered by WordPress. After that, actually getting any practical usage out of it would be pretty much a bonus. The next step datasgeet to mount the hardware — the headphone jack, the variable capacitor, the volume switch and the band switch. Note the orientation, unbend the pins, insert and solder away. Xatasheet, slide the battery terminals into place — positive is the top terminal on the front case, negative is the lower terminal. That way you can flip the board over and solder the leaded parts without them sliding down to the table.
Luckily for everyone, the board also has ccd9088 good silkscreening to judge by the listing. 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.
Otherwise, the IC may not be soldered in the right orientation, or the switch may have been damaged. The hiss swamps out the signal at low volumes which are comfortable for listening in a quiet room … which is disappointing.

The AM reception is being achieved with the CD As an experienced kit builder, I wasted no time in getting started. Do not touch the antenna or you may be burnt! January 25, at 1: In the case of this kit, this specifically includes:. 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. The schematic as listed is shown above. Bench-top supply with crocodile clips, 3V output to power receiver during tuning recommended, but not absolutely necessary.
Repeat for finding a known station, but instead adjust the left brass screw — the higher one. Because there were more capacitors, I decided to tackle them first.
Next, obtain the larger tuning dial and align the indentation. Conclusion After enjoying repairing a few AM radio kits, I embarked on a challenge to build datashet cheap Chinese dual-band radio kit. 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.

Next thing was to solder a pair of yellow wires to the positive and negative of the speaker. Now, the screws need to be sorted and the dials installed.
Of interest is that the reception mode switch actually switches the audio path to the amplifier. Eatasheet two ensures that you have some spares in case things do go wrong … This post will be a little review of the kit, along with tips and hints especially for English speaking constructors.
But at least they did provide the jack.
