After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit. Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason.
February 5, at 7: The case for this was soon found — the components are actually wrapped inside a cellophane bag, but that sort of material has a tendency to tear when punctured by the sharp component legs — quickly the smaller components work their way out.
Hot melt glue, or superglue to stick the speaker, ferrite rod antennas into place. About one to two hours of time to complete the kit. The capacitor markings can be hard to read, but are mostly three digit indicating the first two significant figures and number of zeros in pF.
February 5, at 5: 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.
Get good reception aroun Mhz with correct pointer position. 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.
Take note of the orientation, insert, bend leads, solder and clip leads until all the electrolytics are mounted. Next, solder the speaker wires with both yellow wires going to one SP terminal respectively. In fact, the case even has a few curves to make it look just that little bit more stylish.
Sounds like a demented wasp trying to escape a Coca-Cola can. I have achieved everything, except the connections of the AA Batteries.
For tuning drilled the back for access to datashewt screws on tuning capacitor. Getting to this stage takes about an hour. Having some kit-building experience helps you avoid basic mistakes like this.
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. For this kit, I preferred to do things the opposite way.
It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in. This goes in one direction at the end of the battery compartment and needs to be slid into place in its rails.
A capacitor is hence a 10 pF capacitor, or 0. The AM rod antenna connections can be made by looping out the enamelled wire over the top of the Datahseet is best and tack soldering the ends to AM terminals. Continuing on, the board is completed with the population of resistors.
Hopefully if they forget to include the data sheets, I can print out yours. First, obtain the smaller volume dial and check the indentation for the rectangular brass stud of the switch. September 12, at 3: Now, the screws need to be sorted and the dials installed.
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 capacitor i. Kit Contents Rather unimpressively, each kit comes in a bubble wrap package.
Start by securing the PCB to the front of the case using a short tapping screw on the stud in-between the volume datxsheet tuning dials. Keep the terminals loose on your bench and solder a red wire to the positive and black wire to the negative.
Desoldering braid optional to fix mistakes. For speaker used twisted pair. January 17, at 5:
