I will admit I'm more of a radio operator than an electronics engineer. That is why I'm asking for your opinion.
Many thanks to anyone who sends a reply to my question.
The 6400, at $1999, doesn't have the two SCU's. only the 6600 which is $3999 or $4999 for the 'M' model. I'm hoping that was a typo and that you won't be disappointed hoping an upgrade to a 6400 will be able to listen to 6 maters and your transverter at the same time.

I just bought a 6300 in the past 3 months, and I'm very happy with it (refurb, great price, 2 yr warranty) - I plan to buy the $200 update & keep it, but I am only a casual user.
I believe what I'm saying is true, ive looked pretty good.... if I'm wrong state kindly and ill do even more research.
I also have a 6300, almost bought a 6500 from a friend, he backed out cause flex is giving him a lot in trade towards a 6600m.
I'm glad he backed out, he asked, I agreed....... the 6500 can only use ONE receive antenna at a time, I had thought different before I looked into it, that's the same as the 6300 except the 6500 will do 4 slices instead of 2.
6400 is same way, upto 4 slices but all receive has to be on same antenna, 6600 can receive on different antennas at same time yet still only 4 slices.
So I'm waiting on a 6600.....
I upgraded from 6300 to 6500 a year or so back. Not really worth it in my opinion. Only thing worth having was the band preselectors, but there are much cheaper ways to do this with external Hero box.
I don't use the ATU and the multi-slice capability does not work with most logging apps and 3rd party stuff like JT65. Band vs antenna selection also lacks any intelligence, negating the sweetness of 4-slices.
Are there any measurable RF performance benefits in the 6400? I'd wait for the Sherwood report to be sure.
