Juha, I have 2.7, 1.8, 500 and 250 in my main RX. In the subRX I have 2.7 and 400hz. DSP is usually 200 to 350 hz. Diversity works fine. In fact it's amazing! -Robby VY2SS -- View this message in context: http://elecraft.365791.n2.nabble.com/subrx-and-filters-tp6153441p6160023.html Sent from the Elecraft mailing list archive at Nabble.com.
