I went the 2.8, 400, 200 route in the main RX and 2.8, 400 only in
the sub RX. If I had it to do over I would probably not bother to
"upgrade" the standard 2.7 KHz filters to 2.8. The 2.7 is wide
enough than one can "split the difference" in order to maintain
phase lock in diversity. If one absolutely needs better skirt
performance in a wider filter, adding the 1.8 KHz provides added
flexibility at very little added cost (replacing 2.7 with 2.8 is
$129.95, purchasing the 1.8 or 2.8 outright is only 139.95!).
