How about Cotton Radio and Polaroid Radio in Australia? What about the product? Are they suitable for civil air defense? Please communicate with your used friends. Thank you.

In fact, it is not recommended to use foreign equipment, because it is better to mainly consider domestic independent products for communication. Foreign equipment is mainly sold by some domestic agents, and the cost is already very low (one tenth of the cost), but the price becomes a big problem when it comes down to customers.

In fact, the technology is similar, and the signal processing is slightly better. However, considering the maintenance and after-sales, foreign products are maintained by some agents in China. In fact, they have no maintenance and after-sales ability, and they are still reflected step by step, so everyone should consider this issue.

Besides, let's think about it. If there are 80,000 foreign products and 80,000 domestic products, then communication guarantee is the premise of any work. Which one would you choose in an emergency? In fact, no matter how good foreign products are, we should use them carefully and learn from others' good technologies and applications.

While foreigners' products are provided to you, other investments will follow, which will also cause unnecessary troubles in the later period. Expand domestic demand-capital investment, etc. It is not simply built for your own needs, but to make money for foreigners. It is China people who help foreigners earn money and develop.
