Ask radio enthusiasts and collectors some questions about radio DSP and secondary frequency conversion? Differences among PL600, BCL3000, PL2 10 and PL390

1, dsp radio is a digital signal processing radio with American chips, which is similar to computer processing and completely different from secondary frequency conversion. Secondary frequency conversion is a traditional circuit, which is more complicated. Short wave or secondary frequency conversion is better, dsp has poor anti-interference performance, and dsp is better in frequency modulation, especially in selectivity.

2, both are secondary frequency converters, 2 10 is a small machine, 600 is relatively large, and its performance is of course good.

3. Machines with dsp for fm and short-wave secondary frequency conversion have their own advantages.

4, sound quality, of course, the sound quality of the speaker is better, bcl3000 is definitely the best > 600 & gt390 >2 10; BCL3000 has a cool appearance and good sound quality, which is suitable for enthusiasts-listen, hehe.

I feel that PL600 is Desheng's best laptop at present.
