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. Secure the rear of the case to the front using three long tapping screws on the dataaheet holes, and a short tapping screw on the hole inside the battery compartment. Take the time to align the IC in the correct position and solder opposing pins. 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 occasionally during a signal dip end up getting pulled into an adjacent station over time.
Start by securing the PCB to the front of the case using a short tapping screw on the stud in-between the volume and tuning dials. I actually tried this on my second kit and it was a disaster.
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. You might get static, or nothing. The values can either be read or checked with a meter.
Next thing was to solder a pair of yellow wires to the dagasheet and negative of the speaker. Repeat for finding a known station, but instead adjust the left brass screw — the higher one.
Click for more about me! At this stage, we are ready to make the final connections and assemble the unit.
March 23, at 9: After that, actually getting any practical usage out of it would be pretty much a bonus. Maybe one radio station at the most.

In my case, I ended up substituting a salvaged from another piece of broken equipment … but this is why datxsheet two kits with the intention of making just one might be useful.
The other two battery terminals form the positive and negative. For this, stick the wire through the slot in the rear of the casing, and the screw hole end of the antenna through the slot. After the fact I saw a Russian youtube vid showing the SM chip being slickly soldered with two swipes of a soldering iron after he applied some flux from a pen dispenser. Get good reception aroun Mhz with correct pointer position. Do not fit them into the casing until they are cool, otherwise you will melt the plastic casing!
Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio 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. As an experienced kit builder, I wasted no time in getting started. January 25, at 1: Ordering two ensures that you have some spares in case things do go wrong … This post will be dtaasheet little review of the kit, along with tips and hints especially for English speaking constructors.
Start by identifying pin 1 and straightening bent pins. You can remove the self-adhesive backing from the front window and apply it to the front of the casing, checking the orientation. As a result, I accepted the challenge and cc9088 in an order for two kits. April 25, at Then you can solder the remaining pins and come back to resolder the edge pins. Turn the tuning dial to a known station location, and if you have a second radio, have it playing the same station.
I was aware of the Tecsun 2P3 which looks to be a very nice kit, but a bit dayasheet the pricey side for an AM only radio. So, I rummaged on eBay looking for radio kits, and surprisingly, there were quite a few! Unfortunately, the instructions are only a single double-sided sheet, so the educational value of the kit is somewhat limited.
Once roughly in place, you can take the AM-FM mode switch, deburr the plastic and push it through the exterior casing over the switch.
