Keep the terminals loose on your bench and solder a red wire to the positive and black wire to the negative. Proudly powered by WordPress. November 24, at 8: It also gives you the best access when soldering SMT parts.

Two AA batteries to power the receiver. 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. From here, we can mount the cd9088 copper air-coiled inductors. We start by first emptying all components into a plastic bowl so they can be sorted through.

Because there were more capacitors, I decided to tackle them first. Will see if it works as well as yours did. Sound quality is good. I made do with dafasheet Weller iron but it was a challenge. The plastic casing is light, slightly weak to flexing and has a tendency to resonate at certain frequencies causing a buzzing sound at higher volumes.

Conclusion After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit. For tuning drilled the back for access to adj screws on tuning capacitor. March 23, at 9: 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.

I wonder if adding some holes in the back of the case would help. November 10, at 6: Once it is soldered, the speaker can be glued into the front casing with hot melt glue around the edge or superglue if unavailable.

I agree about the SMD Hot air re-flowing. A flat bladed screwdriver helps. Repeat for finding a known station, but instead adjust the left brass screw — the higher one.

September 8, at 1: 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. Do not touch the antenna or you may be burnt! At this stage, we are ready to make the final connections and assemble the unit.

For speaker used twisted pair. February 5, at 5: Hopefully if they forget to include the data sheets, I can print out yours. I did have problems with the jack but left it misaligned. Dagasheet AM reception is as per most TRF receivers — not particularly high quality and it seems that this is prone to overload.

It seems to have a lacquer finish to stop the pads from oxidising, but is not otherwise tinned nor plated. Would have liked the legs on the FM chip a bit longer, would have been even better if chips had fitted into DIL sockets. One time I even reduced the turns on one of the coils. I enjoyed a lot this kit.

After that, actually getting any practical usage out datashfet it would be pretty much ce9088 bonus.

A capacitor is hence a 10 pF capacitor, or 0. I actually tried this on my second kit and it was a disaster.

Maybe one radio station at the most. Next, obtain the larger tuning dial and align the indentation. Then you can solder the remaining pins and come back to resolder the edge pins.
