Mark, the roofing filters on 1.373b5 or b3 don't kick in at the same
place relative to the dsp bandwidth filter as they do in 1.372. In
1.372 the bandwidth of the roofing filters kicks in when the dsp
bandwidth reaches the bandwidth of the roofing filter, when going
narrower. That is, when you have your roofing filter selection set to
automatic, and you turn your bandwidth control narrower, the 2.4 khz
filter kicks in at 2.4 khz, the 1 khz filter kicks in at 1 khz, etc on
down.
But in 1.373, the roofing filters won't kick in right away. There is a
lag kicking in the roofing filters regardless of whether you are
narrowing or widening the dsp filter. So you may have a dsp filter of
970 hz, say, and a roofing filter of 2.4 khz, and have to go to 960 hz
with the dsp control until the 1 khz roofing filter kicks in. Then as
you widen the dsp filter you may not get back to the 2.4 khz roofing
filter until you hit 1.040 khz with the dsp control.
No biggie, but I prefer 1.372. --Brent N9HZ
