Bottom end of the audio passband at 500 because all heartbeats etc. should normally be in 500-1000Hz range. As to bandwidth, I am in a very noisy City environment in London. My antenna is a 12m end fed wire tied to the top of a wooden fence - and half of that length is shielded as it is between two houses.
A narrow bandwidth simply keeps the noise levels down, but will still capture virtually all the JS8Call traffic. 80m is unusable unless I can narrow the passband right down.
