Produto como descrição. Montado e testado, funcionando bem como esperado. Receptor AM de alta sensibilidade e som claro.
This one worked right from go. You will need to adjust the IF cans to get the reception . Good case that closes well with a good fit. The 1950's blue colour is a plus too. Antenna coil is well put together...but take care in mounting the 4 wires to the A B. C. D terminals. A and D are easy... I managed to reverse B and C. It was a fun build that took about 2 hours. I would buy this again, build it and send it to a friend as an xmas gift. Its cool.
Посылка шла почти два месяца. Упакованная качественно все целое всего хватает!
received in perfect contition!
This is a fine kit to do as a learning exercise. The radio does actually work, we can get 2 channels and it is very tinny, but I think that is a good result! I built this with my 10-year-old, he soldered and I supervised. He is very excited that it works. Note the instructions are in Chinese, and although the position of components is marked on the board I would have come unstuck several times without the various youtubes and web pages you can find on this kit (look for HX-6B). The most useful was: usefulcomponents.com/main_contents/projects/chinese_superhet/chinese_superhet The radio did actually work, we could get 2 channels and it is very tinny, but I think that is a good result! The kit had everything needed, we only needed a small soldering iron, nimble fingers, and a very few standard small tools. Delivery took around 6 weeks, longer than I anticipated but the pandemic may have been a factor. There are other kits available based on a chip, but then you get to see nothing of the circuitry or the components that go into a radio.
Radio works. With no English instructions I had to jump through some hoops along the way. Chinese symbols next to T2, T3, and T4 are colors. Match with resistor color chart on schematic.
Transporte rápido. As peças no kit são boas. Apenas a embalagem é novamente bastante decepcionante. Proteção insuficiente dentro do saco de plástico.
