连接收音机调谐旋钮的调谐线长期磨损易断,往往难找到合适的代用品。钓鱼线拉力强、弹性好,价格便宜,易购。用它当收音机的调谐线既经济又耐用,而且还克服了多绞股线容易使调谐指示针打翻斗的现象。便携式收音机用0.3毫米的钓鱼线为宜。本人用钓鱼线更换了数台收音机调谐线,效果非常好。◆ Tuning lines connected to the radio tuner knobs are subject to long-term wear and tear and often find it difficult to find suitable substitutes. Strong fishing line, flexible, cheap, easy to buy. Use it as a radio tuner line is both economical and durable, but also overcome the phenomenon of multi-strand strands easy to make tuned pointers hit the bucket. Portable radio with 0.3 mm fishing line is appropriate. I used to replace the fishing line several radio tuner, the effect is very good. ◆
