Hello Don, Thanks for the quick response. I was just going through the K3 manual and KE7X's excellent book, but haven't seen any reference to that. For general ham radio operation I don't see it as a limitation, but it's a bit disappointing that the FM filters that will arrive tomorrow along with the 2nd RX, won't provide the capability I was hoping for.
