Hello guys.

Sorry about all the questions but I think this is the last one before I press the "buy" button for a K3.

Once again a question about cw roofing filters.

I am initially ordering the K3 without the 2nd receiver but do plan on getting one within a year.

That said, and knowing it's best to have 'matching roofing filters' for both receivers, even after all the reading I still have no idea what would be the best roofing filter to get. It seems to be such an individual choice. Ideally, I'd prefer to purchase only one filter (or one for each receiver) and want to make the best filter choice for my operating.

So if I order the K3 with no roofing filters, can I determine from operating with just the DSP which cw roofing filter would be the optimal one for me.

Or is the above an exercise in futility and I just need to order say a 400 and see how that does before I'll know?
But then again I guess it wouldn't be 'matched'' when I get one for the second receiver.

Too many decisions!

thanks again.
