I think these radios do just fine with weak signals on 40M or lower where
the atmospheric noise is higher.  I put a passive DBM in front of a BC-453B
 and it will capture whatever is above band noise.  Stability is good too.
 The issue is CW selectivity.  You get used to what we did as novices, use
the analog signal processor between our ears.
