Hi Dave,
Let me first clarify that when I say “My best…” I am only looking for weak signals on 2m via moon or Digi tropo. I am not looking to chat on FM with 15 other stations within 30 feet of me on 2m. That is to say that my noise on 2m is not made by local Hams.
My tests are not Lab tests. Please see my pics on
My main way of testing is to find a weak CW beacon or set up a JT65 beacon and add attenuation until the signal disappears from a common waterfall. My view is that if I cannot see it then I cannot work it. OK that may not be 100% true with JT65 but you get the point. I have done this test on several of my 2m RX including my USA made TVTRs, a few Icoms, a TS2K and my baseline RX of a FCD+. Long story short the DL TVTR comes out “Best” in my world by far apart from when compared with the FCD+. It is, in my world, better than the FCD+ but the jump is no where near as big as when comparing it to the others.
This is the DL TVTR I use. I think at last exchange rate that I looked at they were $357 shipped?
