Hello everyone, I'm new on the forum. I hope I am in the right place and section to clear my doubts. Otherwise, I apologize. (and sorry for my bad english). The query is the following, I wanted to clarify about why car radio has a much higher sensitivity than conventional receivers. Is it due to greater sensitivity in the electronics of the device? Or because of the good quality of the antenna they use on the roof? I have a Tecsun PL-360 receiver, and according to the technical specifications indicated in the instruction manual, its sensitivity in FM is 3 μV. Whereas my car radio has a sensitivity of 0.8 μV in the same band. From what I understand, the smaller the number of μV, the more sensitive the device is. On the other hand, I have seen handys for example from the Baofeng brand, model uv-r5, which in addition to VHF, brings the option of listening to commercial FM (65-108 MHz), whose sensitivity according to the manufacturer is 0.2 uV . My question is, because car receivers have a higher sensitivity than telescopic antenna ones? Is it because of its external antenna or is it because of the high sensitivity of the receiver itself? About the aforementioned handys, are they really more sensitive than the receiver of my car radio? Thank you very much in advance and I apologize if I am consulting the wrong section.
