The 400 Hz INRAD is probably the best compromise.  Wide enough for
tuning the band but good skirts/reasonable selectivity.  The 250
would seem to require rather critical tuning.

I find the 1.5 KHz filter to be too tight (I have a couple).  It
requires too much adjustment to be useful, particularly in the
"heat of "battle."  The overall difference between 1500 and 1800
in the IF doesn't mean much when using a more narrow DSP setting
but it is significant in ease of use when tuning.

73,
