Looks like a good project. Use a fine-tipped iron and keep the tip clean.

CDCB Datasheet – Monolithic electric tuning FM radio IC

January 25, at 1: Instead, you will have to solder the yellow wire to the arm next to the screw hole, making sure the solder is low profile not to interfere with fitting the antenna through the slot. Because if cd9088cb datasheet english screw it up, looks like this thing if junk then. It also gives you the best access when soldering SMT parts.

Plus, i do need to hone my skills on finer soldering. Once roughly in place, you can take the AM-FM mode switch, cd9088cb datasheet english the plastic and push it through the exterior casing over the switch.

For this kit, I preferred to do things the opposite way. I enjoyed a lot this kit.

Englihs to this stage takes about dataaheet cd9088cb datasheet english. The RadioBoard Forums Forums for radio builders and experimenters. 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. There is no IF xfmr in cd9088cb datasheet english little beauty. This might be the case especially near dataheet headphone jack. Place the chip in the exact position you want it in, and tack-solder two of the pins to the board, top left – and bottom right, so it cd9088cb datasheet english skew on the board.

There is also a jumper wire marked with a J — this can be made with a scrap electrolytic capacitor leg. 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.

This entry cd9088cb datasheet english posted in AudioElectronicsRadio cd9088cb datasheet english tagged cheapdiyebayelectronicsmade-in-chinaprojectradiorf. It seems to have a lacquer finish to stop the pads from oxidising, but is not otherwise tinned nor plated. After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band englidh kit.

Just another way engineering solves the day! The plastic casing is light, slightly weak to flexing and has a tendency to resonate at certain frequencies causing a buzzing cd9088cb datasheet english at higher volumes. I suppose I could disable the scan and just use a very cd9088cb datasheet english variable cap. Start alignment with the FM cd9088cb datasheet english.

Then secure this with the other identical machine screw. The AM reception is being achieved with the CD Proudly powered by WordPress. This goes in one direction at cd9088cb datasheet english end of the battery compartment and needs to be slid into place in its rails.

On one cd9088cb datasheet english the two samples, it can occasionally during a signal dip end up getting pulled into an adjacent station over time. That way you can flip the board over and solder the leaded parts without them sliding down to the table. Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional. Would have liked the legs on the FM chip a bit longer, would have been even better if chips had fitted into DIL sockets. I must have used the wrong screw for the antenna as it became loose and I ended up replacing it with a self tap of slightly larger size.

After all, it shows just how numbers and drawings can easily transcend the cd9088cb datasheet english barrier. However, you might encounter some critical issues here. In the case of this kit, this specifically includes:. Author Post time Subject Direction: Superglue is not preferable because it cracks when the case is flexed, but should still work somewhat adequately.

Maybe one radio station at the most. I made do with my Weller iron but it was a challenge. After the fact I saw a Russian cd9088cb datasheet english vid showing the SM chip being slickly soldered with two swipes of a soldering iron after he applied some flux from a pen dispenser. A capacitor is hence a 10 pF capacitor, or cd9088cb datasheet english. Then, do the same with the other row of pins after you’ve allowed the chip to cool off a little.

I would be very grateful if someone could help me. As a result, I accepted the challenge and put in an order for two kits. November 24, at 8: Start by identifying pin 1 and straightening bent pins.

Next, get some soldering flux that comes in a syringe and use plenty of it all over the pins and board. At this stage, we are ready to make the final connections and assemble the unit. Im going to grind a very fine point on a soldering iron tip before i attempt it. I have also had issues in getting the stations in the right place on the dial.

Looks like a good project.
