I see the width of the modulation on screen and set the filter accordingly.
Some AM stations are as much as 20 kHz wide. The D/A speed has to be set 
higher than the modulation bandwidth and the mixer bandwidth reduction must
be set small to allow 20 kHz output bandwidth. Most AM stations are 10 kHz
wide and I typically set the bandwidth at 10 kHz for AM.

Yes. I already found this bug (and corrected it). There seems to be several
problems with Linrad-01.18, I will soon upload  a Linrad-01.18a with some
corrections including the AM volume.
