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.
Buon kit di apprendimento del circuito è di buona qualità la radio funziona molto bene e non deve nulla per le radio acquistate dalla fabbricazione buona sfida.
Sembra promesso, te lo dico quando la prendo.
Модель для сборки очень интересная. Это реплика приемника Sony, так что собирать будет интересно. Единственное Доставка была ну очень долгая. СДЕК вез 2 месяца. Главное приехал в целости и сохранности. Качество пластика (корпуса и внутренних деталей) на высоте. Спасибо!
The item was delivered very fast. The full and true description of the item. I recommend everyone.
E'arrivato oggi. Sembra che non ci sia alcuna rottura, ma penso che sia meglio avvolgerlo con un materiale per cuscini e metterlo in una borsa DHL per ridurre il rischio di rottura. E'arrivato oggi. Apparentemente, sembra che non ci siano danni, ma penso che il rischio di danni sia migliore se lo avvolgi in un materiale ammortizzante e lo metti in una borsa DHL.
Few parts were mismatch .Brocher was in language other than English which I ciuld not understand.Having knoledge and experience of electronics I could assemble the kit.It is very difficult for beginners to assemble it.Legend on the pcb and parts mentioned in circuit diagram did not match at three places. Coils/ transformers T1 T2 T3 and T4 are difficult to identify as brocher is in unknown language.Antenna coil lead details are not mentioned.After assembling FM band functioned well as it uses CF 10.7 serves pre tuned.But AM band does not respond well including SW bands.It only create noise and does not receive any radio station broadcast. If possible please e mail me an english version of bricher.Thanks.
This is my second kit.First one did not work 100%..Second one everything works,but with no instructions provided I could not figured out how to completely assemble the tuning mechanism,so I could not complete my kit.. Real shame because the radio works fine.More details instructions are needed to assemble this kit.Perhaps other being luckier than me.
