Some disappointment with this kit. 1) No instructions. I downloaded the schematic and Bill of materials. That helps. Missing some key pieces. I would accept instructions written in Chinese. I can translate enough to get through a build. (Thanks to Google translate) 2) IF transformers (cube looking metal cans) No indication of which one corresponds for which L. Here is the key to figuring it out. T101 = Red (AM OSC. Coil) T102=Green / Blue (SW1-4) T103=White (SW5-7) T104= Yellow (AM IF Transformer) Took me some time researching this. See uploaded photo for locations 3) Ferrite loop antenna wires See uploaded photo for connection points. (Found these photos on an auction site that was selling this radio for ALOT more than banggood. Glad I purchased it here.) 3) Tuning indicator. This is a puzzle you just have to figure out. Not really hard but difficult to explain. I may try to add instructions for this later. Right now just glad the radio works. I'll purchase another from here and do a step by step instruction in English with still pictures and video. Otherwise a great kit for the price!
Not for the beginner you need to down load schematic etc from bangood website am ferrite coil consists of 3 coloured wires schematic does not tell what colour wire goes where unless you know how to read the coil use ohms on multimeter will help.No instruction on how to assemble tuning mechanism so you get a puzzle as the bonus.After assembly this radio works very well after alignment of the various IF coils and FM coils . Overall a very good radio for the price.
