When I ordered my K3S I got the 2nd receiver, general coverage and message recorder cards. Does any option added preclude install of the 2m option? I’m thinking to try 2m WSPR and FT8, as limited as those may be - will these work with the 2m option added to the K3S? Bret/N4SRN -- Sent from: http://elecraft.365791.n2.nabble.com/
