False alarm! I forgot that the M37V uses a 450 khz filter, and so
the images are only 900 khz away.
BTW, you know what the reason for 450 kHz is? With a 3 or 9 kHz
PLL reference frequency (and thus granularity), you'd never hit
the 9 kHz frequency grid precisely when using 455 kHz. (Same
goes for a 10 kHz reference in 10 kHz territory.)
