Think you have that pretty much sorted Jim. I have an 8 pole 250Hz roofing
filter in my 2nd rx as I thought it would be good for 'mult-hunting' during
contests but in reality hardly ever use it.
Not sure how important it would be to insist on a matched 2.7KHz filter
either. Because the bandwidth is so high you can simply make the small
'centre frequency' adjustments in software without affecting performance
hardly at all; obviously more of an issue for the narrower filters...that's
my understanding anyway.
You'll really like having the 2nd receiver...have fun,
