Thanks for the reply, As I require diversity , the K4D is necessary, as I also require an autotuner, I need that as well. The costs are adding up.
I certainly don't want a new rig that has in any way, less capability than the fully loaded K3s I have now. If a K4HD with autotuner is functionally excess to my having a K4D with autotuner, that helps me budget. 73, Gary KA1J > Any of these things you mentioned might not bother you now BECAUSE > you are using a K3. > > The K4D adds a second A/D chain with dedicated front end filters for > whatever band the second receiver is tuned to.
