Hello, I am thinking to buy KRX3. The main K3 I have 2,8 kHz and 400 Hz filters. What I need to subRX? Is 2,7 and 500 good choice and do I need KFLMATCH? juha - oh6os K2#4781 K3#2100 -- View this message in context: http://elecraft.365791.n2.nabble.com/subrx-and-filters-tp6153441p6153441.html Sent from the Elecraft mailing list archive at Nabble.com.
