The Anan 100D simply has another AD converter. Why bother? Diversity reception and if one needed 14 receivers verses 7 then the 100D would likely be of interest.
I have not seen controls to route audio from 1 Reciever to one ear and the other to the other ear. You would have to ask that one in the yahoo group.
You can right now make the Anan stitch receivers together for larger swaths of bandwidth or spawn receivers individually on the same or multiple bands. Because your dealing with 380K receivers or smaller if you desire you can see entire bands or spawn receivers on the same band.
If you watch the CuSDR video you can see at the top that it shows the whole HF spectrum and what is very nice is when you have a given receiver with focus you can click anywhere on the spectrum and it will pop that receiver to where you clicked. You can see I clicked on the big signals and went there immediately.
Right now the limiting factor is the network width which is not set to a full gigabit wide. Once we have that (very soon) then one could tap into all 14 receivers.
The Xmit code for cuSDR will move along quickly now the Helmut got some help from Apache.
Sandro over at studio 1 is working on Xmit code for Studio 1 as well and there is an EXTio dll under development for the anan by a ver sharp developer out there I have done some testing for. I have had 5X receivers up on it and I could probably make that even more by spawning additional receivers on the same bands as any of the 5. Note to myself to try that, lol.
What lacks a little right now is full controls for each Reciever in most of the packages that work with it. I have played with one that the controls are fully functional for each RX. This is also possible in time for all the packages.
There are some Anan 10s online you could access with cuSDR to get a taste if you look.
What's cool is you are not tied to one developer, there are lots of developers doing lots of things.
I will go on record as saying that if Sandro gets the Xmit code working on Studio 1, that software for a 1 time $200 purchase will totally blow Flex's offering away as far as elegance goes, and I also think as far as usability goes.
Here is the bottom line in my mind. Flex right now has a semi sure path for the thin clients which will let you eventually ham on a clients that may or may not be written for the iPad and other tablets, devices ect.
We don't know if we will get that on the Anan and I don't see that as a focus right now. That said, I don't see hams doing what I call REAL haming on iPads. It's a novelty at best. Sure, they'll make QSO,s, ect on iPads, that's not my point. I am talking about sitting down at a fully functional station and doing what you want, how you want and when you want with all the controls at you finger tips. Maybe in some years haming will be seen different and more watered down, but that's not what I am really wanting. You have seen how I like to ham!
Again, don't listen to me, go do the homework, that way when you get your radio you are not suprised like the Flex 6K series buyers who will be waiting for even the basics. SDRs are still not for everyone, so that's my warning. Unless it was purely a reliability issue for you on the flex and the missing functionality, then you may want to be careful. The Ethernet connection is rock solid so no sputtering or crashes in QSOs an the Anan. Also keep in mind I built me a whale of a computer in HamZilla. Little Latency and a 450 double barrel hemi under the hood!
CW, you need to probably explore that one well. I am not the guy to comment. I simp,y suggest going on the Anan forum where many of the fathers of SDR hang out sometimes.
