Replying to myself...

> an RC low-pass filter, with a -3 dB corner at 2.4 kHz

After finding a better scan of the receiver schematic, what I thought was a
2k resistor as R34 is really 1k, so the corner is 4.8 kHz.  Based on that, I
doubt even more the HF roll-off is the reason your calibration is failing.
