I have played with some handheld radios, which is relatively cheap. The biggest reason is that it is affordable and has multiple functions.
Recently, I went to a friend’s construction site and showed me a Motorola walkie talkie, the Mag One A8. It is said that due to unknown reasons, it has been scrapped.
The A8 walkie talkie belongs to the keyboardless professional walkie talkie, with a low frequency range of 400-420MHz. Those with strong hands-on ability can be spread to professional bands.
High sensitivity, clear and loud sound, non explosion-proof, suitable for engineering, property management, and other non explosion-proof workplaces. Getting started is heavy. Of course, the main reason is that the weight of the battery is there. The host is actually slightly heavier than domestic ones. Before the A8i was launched, a single battery was priced at over 500 yuan. Nowadays, second-hand salted fish can only cost one battery. The scrapped battery should have already been scrapped and is not worth buying a new one. It can only be dismantled and taken for a look.
Once you enter the theme, the process will not be posted, just open it directly。
This is a speaker, which is glued to the casing and then pressed down with a thickened stainless steel ring. The specific speaker parameters cannot be seen.
There are a total of eleven screws to fix the motherboard (the first screw accidentally fell to the ground and ran somewhere), compared to a domestic model with only four screws.
I have used a lot of physical components, and the biggest advantage is that if one breaks down, it can be replaced, and the anti-interference ability is also good.
This is the connection between the motherboard and the bottom aluminum plate, coated with silicone oil, which can enhance heat transfer and increase heat dissipation like a computer CPU. There is no domestic radio available.
Recent photos of the chip and some of the original components.
Compared to a certain domestic product, if you don’t know the industry, the technological level is not as good as that of domestic products. After all, domestic products mainly rely on various integrated circuits, and analog signals are always distorted after being converted into integrated circuits and combined with interference. As long as an integrated circuit is broken, it is basically scrapped.
And for A8, if a professional inspection shows that the original component is damaged, it can be replaced separately.
Overall, existence is reasonable, and various combinations of methods have their own advantages.
