On 80m/40m/20m the ubitx receives as well as my FTDX3000. Those bands,
esp 80m/40m, are noise limited not sensitivity limited. The 3000, of
course, has more filter options which helps control received noise.
However, an audio filter with a peak mode significantly helps the
ubitx on cw.
On the higher bands a pre-amp might help. That can be added in the
receive path just like nd6t's agc circuit and can be switched in and
out at need.
