CD9088 DATASHEET PDF

Shaktikree Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason. Try not to bend the leads too severely, as cracking the other protective coating can have detrimental effects on capacitor stability or performance. On one of the two samples, it can dc during a signal dip end up getting pulled into an adjacent station over time. The capacitor markings can be hard to read, but are mostly three digit indicating the first two significant figures and number of datasheet in pF. Magnifying glass and light to read small component values and markings also optional.

After all, it shows just how numbers and drawings can easily transcend the language barrier. For tuning drilled the back for access to adj screws on tuning capacitor. Note the orientation, unbend the pins, insert and solder away. March 23, at Cool kit and fun to build.

Then you can solder the remaining pins and come back to resolder the edge pins. My board looks like this — ready for the population of resistors. The next step was to cd the hardware — the headphone jack, the variable capacitor, the volume switch and the band switch. Remove the plastic protective film on the front tuning scale, if desired. However, you might encounter some critical issues here.

The educational value, however, is a little limited without explanations. September 8, at 1: But at least they did provide the jack. Maybe one radio station at the most. Keep the terminals loose on your bench and solder a red wire to the positive and black wire to the negative.

Lead the yellow wire to the ANT terminal and tack solder. November 10, at 3: This goes in one direction at the end of the battery compartment and needs to be slid into place in its rails. The schematic as listed is shown above.

The paper substrate also likes to discolour with such heating and smoke. Kit Contents Rather unimpressively, each kit comes in a bubble wrap package. 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 …. The plastic casing is light, slightly weak to flexing and has a tendency to resonate cd certain frequencies causing a buzzing sound at higher volumes.

I have found the AM section to be very un-selective. Proudly powered by WordPress. As a result, I accepted the challenge and put in an order for two kits. Luckily for everyone, the board also has very good silkscreening to judge by the listing. January 17, at 3: Getting to this stage takes about an hour.

Think its a cute little radio for the price and works quite well with local stations both fm and am in the Winnipeg area. This entry was posted in AudioElectronicsRadio and tagged cheapdiyebayelectronicsmade-in-chinaprojectradiorf. Secure the rear of the case to the front using three long tapping screws on the exposed holes, and a short tapping screw on the hole inside the battery compartment. For speaker used twisted pair. September 12, at 3: November 10, at 6: About one to two hours of time to complete the kit.

To adjust the FM alignment, you need to use a flat blade screwdriver and adjust the right brass screw on the rear of the variable darasheet i. March 23, at 9: Take care with the ceramic disc capacitors not to lose them as some are extremely small. Use the slightly different machine screw to secure the antenna to the rear casing. As an experienced kit builder, I wasted no time in getting started.

Kejar By now, most of the remaining components are resistors or capacitors. Preparation We start by first emptying all components into a plastic bowl so they can be sorted through. Rather unimpressively, each kit comes in a bubble wrap package. Hi, I have had made it 3 times, and the last was today. Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional.
