I'm thinking an inexpensive DSP radio, tuned to 455 kc, might be the Q5er
of the 21st Century.

Yes. And other than the BC-453, there haven't been a lot of small
receivers that tune the LF band except more recent portables.

Though, make sure the portable you use allows for variable selection, and
not all of them have a BFO, so no SSB/CW and no synchronous detection.
