Sk8111107 Some people recommend the RSP1, but I've noticed that most listings on Taobao seem to be for counterfeit versions. Will the performance of these knock-offs be significantly different from the genuine product?
BloodBlade A reviewer from overseas found that some of the smaller, TV-like devices were not as good as the original, but one larger device had performance very close to the original. (https://www.hackster.io/mircemk/short-review-of-chinese-clone-version-of-sdrplay-rsp1-4a8e93)
BI1QKA BloodBlade Wow, I just bought one randomly like this, and it seems to work well. However, the environment isn't ideal, so I'll try taking it out next time.
BG2EFX If you're concerned about performance, buy the original version. In the field of radio communication, the principle of "you get what you pay for" still holds true.
BH4FCY The RASP1A from Jezzi is very good; I compared it to the original and couldn't see any difference.
