It is close in sensitivity to the 396xt and 996xt. Close. Uniden set a baseline standard for me in that department, and it is hard to go back / stray with other manufacturer's lesser sensitivity specs in the civil and milair bands. When they don't publish those specs, actual usage shows them to be much less sensitive than any Uniden. (The RS/GRE Pro404 / 106 / PSR500 etc - not to mention an unbelievable use of dual-conversion/10.7 mhz IF in the 404/200 line).
But sensitivity specs aren't everything. Along with that is a quality front-end, and the Unidens have always had better performance in this area than rs/gre. That's not to say they are bulletproof. But with the 370, I was really concerned about FM desense/overload, but the 370 is holding up as well as my 396xt in that regard. I don't know if Uniden is using more / better bandpass filtering or what, (they could actually use this as a marketing feature). And the fact that they weren't tempted like GRE to go back to dual-conversion in their inexpensive line is a big plus!
And the CRS units have better / louder audio than any handheld, that's for sure. You won't hear it inside a noisy hangar, but at home no problem. The frequency response was pleasing too. I don't care how many features a scanner has, if the audio bugs me. The 370 sounds good. Once you get a taste of AM Airband ops with nice fidelity - oh man, is it hard to go back.
I didn't do any airband back when I had a '43, but I did appreciate the triple-conversion. However the audio made me frustrated. The 43's scan speed of 25cps was ok back in the day, but the 370 just about triples that. That may be important depending on how you use it. I have never owned a Yupi, but from what I've read, the scan speed of the 370 might be near triple too (although research shows that in actual use, it may be 75cps - can't really say). I would think that the 370 would be a welcome addition. I tend to use narrow-banded antennas these days as opposed to discones on scanners, and even my homebrew milair-folded-dipole up in the attic makes the 370 sing. Even with bedside radios, I try to keep the antennas away from lighting etc.
I'd love to see a BC125AT-like upgrade to the CRS series! But if you are like me and have memorized most of your local spectrum, no problem.
