AM Broadcast Band portable radio kit.
English instructions - built one myself in a couple of hours - works very well see the video.
Components individually bagged and labelled. Resistors, being very small the colour codes are quite difficult to see, so these come pre-sorted and identified on a resistor component sheet to ease assembly.
Recommended that you have a simple multi-meter available but the kit can be constructed sucessfully without one - multimeter can be used to check circuit currents, as shown on the circuit diagram at test points which MUST be solder bridged for the circuit to function. This is a good pre-test to make sure the circuit is operating correctly, in case of faulty components or solder bridge somewhere on the circuit, prior to final setup.
It's all in the instructions I have written.
The little radio covers: 1600 kHz is a frequency in the commercial Amplitude Modulated (AM) radio band, which ranges from 540 kHz to 1600 kHz. AM radio carrier frequencies are assigned at 10 kHz intervals. There's plenty of English station in the UK: Talk Sport, Virgin Radio local BBC stations in certain areas to tune into and in the evening the continental station become louder.
Radio is directional as it used a ferrite coil aerial - no exteranl aerial required.
Full assembly guide included full of step by step images and 'english' instructions will be provided.
Product Selling Point:
The circuit contains 7 transistors, so it is called 7-tube radio. (tube=transistor something lost in translation)
Condition: 100% Brand New Item Type: Radio Electronic DIY Kit Frequency range: 5251605KHZ Output power: 100mW (upper limit)
Speaker: φ57mm, 8Ω Power: 3V (2 x AA batteries) (battery not included) Volume: Approx. 122 × 66 × 26mm / 4.8 x 2.6 x 1in
The secondary medium amplifying tube is standard circuit, and the intermediate frequency has been adjusted to 465KHz.
V1 is the frequency conversion transistor, V2 and V3 are the middle frequency transistors, the V4 is the detection transistor, V5 is the low frequency preamplifier transistor, and V6 and V7 are the low frequency power amplifiers.
Product Specification:
Product Name:Electronic HX108-2 BOSHI XILIE DIY Kit
All thru-hole components - No Surface Mound Devices so basic soldering skill required.
The PCB has all the components identified on its top surface and matches up to the parts list I will provide and the circuit diagram. The soldering pads and tracks are sufficient and I had no trouble with solder bridges or pads coming off of the PCB during my construction.
Size:approx. 122*66*26mm
Color:As picture
Weight:200g
Frequency Range: 525-1605KHz
Output Power: 100MW
Power Supply: 3V (2 x AA cells) (Not included)
Here's a link that describes extending the range of an AM radio - I have not tried this method as yet - let me know if you try it and it works?

Just purchased this kit from you and it looks to have been a lot of work putting together the English instructions etc
can't wait to dive in. cheers Michael
