New to me, but found this  http://eesdr.com/en/

Looks like an SDR in the traditional knobs and buttons box, CPU, etc....  

Thoughts?

They have been around. Another SDR company like Apache Anan and a couple others.

Looks like a nice rig but it's pricey ($5500), needs to be pre-ordered and has no support in USA.  I've been following it for the past two years.  There are many youtube videos.

That is more like what I thought Icom was going to come out with.

It is apparently available outside the US. I suspect it will be available with the pre-Dayton offerings from everybody.

NO, not the 7300, I'm talking about a high-end direct-sampling radio with a high resolution display!

Is this Sun radio direct sampling?

Great to see the marketplace evolving towards SDR. Best innovation in radio design in decades.

Agreed. But that was bound to happen. Totally inevitable. Nobody would turn down the chance to use a round wheel when somebody had the idea of taking the corners off a square one, hi hi. I don't know who invented the concept, but Flex can be only part, maybe a small one, of the whole SDR ecosystem.

Didn't flex do this years ago with the 1000..ie built a computer and sdr into one box, ok no knobs but what happens when the i5 is obsolete..mind you the wee sunsdr2 is nice, i have one on loan at the minute but I think I still prefer the Flex because of the support and 3rd party applications like ddutils to control the rest of the station.

what happens when the i5 is obsolete
I don't think that's necessarily a valid quesiton.  The cpu is dedicated to running the SDR control software.  It will continue to perform that function going forward.  Any radio made in the past 25 years has microprocessor(s) inside and the radios continue to work just fine despite those chips being long obsolete.

While I agree with you Barry, so long as the original I5 is not fried but once the chip is fried and the I5 is no longer made....I haven't bothered to check but is the 8085 still in production? I built a Heathkit Computerized Weather Station. I had the anemometer and wind vane at the top of my tower. It got hit several times and fried the main cpu chip inside the station box proper. No problem, I ordered another one, inserted, back in business. Eventually I couldn't find a replacement chip. Bye Bye Heathkit weather computer. Granted, that took awhile to happen but it did happen. My TS-530SP has a tube final. I think I'd be hard pressed to find a replacement if the current one goes.

Your arguing that you should never buy a radio with an embedded LSI chip that might eventually fail because you might not be able to find a replacement part in the future when it fails?

What about the ADC and DSP chips in all these radios?  Doesn't the same argument hold for avoiding them?

No. Sorry, I was just making conversation. Who knows, maybe China will be making I5 (or Heath LSI) chips as long as any of us are alive.

I have two Russian friends.  Great people, nice guys.  However I could not even conceive of trying to get tech support on something so complex as SDR from Russia.

I realize they don't support US yet but I'm sure they probably will if their product goes well.  But think about Tim and FRS and how easy it is to talk to experienced users and for virtually all of us in the US, (like you George...) shipping our Flex units back for TLC is at worst a couple week ordeal.

Could you imagine applying DC to the antenna on that thing?   You'd be out of a radio for months.

It is available in the UK for GBP4,600 (if you include the ATU).

For myself, I have never had any regrets about deciding to go down the FRS route, and I did consider this radio as well as others from India and elsewhere.

@ David G4NRT

If I had that sort of dosh to throw at a rig, I would have bought a higher specced Flex. That the Flex is made in the USA was a big plus for me, so much so that I did not consider other SDR rigs. Native English speaking tech support too was just icing on the cake.

Couldn't agree more Guy! I just wish that I could have stretched to a 6700 but I only just managed to afford a 6500 + reserve for a Maestro!

David, That's the route I've gone down (6500 and deposit on Maestro). To be honest I think we've hit the sweet spot of specification and 'usable' functionality.

The sweet spot in bang for the buck.  The price delta to the 6700 is too high IMHO, especially for those of us who principally just want a second hardware receiver.

Looks like 2 dealers in the US at this time:
http://www.cheapham.com/
http://nsiradio.com/SunSDR/

But as stated support would be a nightmare...

Looking at the back, I see HF (4), VHF(2), UHF(1) and what is this SHF????  new to me.. is that microwave?  All in one box??  I understand the reason for the 4 fans, betting this thing gets HOT

For $5500, I'd expect to at least see a TRS (balanced) mic input and line in/out.

Im also in agreement with some... I like the idea of being able to upgrade my computer hardware as I see fit.. not just stuck with a particular processor.  from what I've seen you can run an additional screen off this, so that gives you two... one tiny and one of my choosing.. however right now I'm currently running 3 22' wide screens and for speed I'm running solid state hard drives (2), and I can upgrade whatever I want... this one would be stuck with what you get... 

Just some thoughts...

I am just being devil's advocate here. In the case of PSDR, yes, you are absolutely correct, being able to update your 'radio' (as the PC is your radio) is crucial.

However, with SSDR upgrading your display is irrelevant to the speed of the radio software as it is self contained. So, independent of what your PC is now if running SSDR the GUI leaves you with an aggregate cpu rate of <99% you have available processor. The gating factor is the speed of arriving UDP packets which doesn't come close to 1Gbs the nic is likely capable of. I believe Steve or Gerald said the Maestro's 100Mbs nic was because even at that, there was plenty of available bandwidth.

No need for a Gbs nic. One can't display the data faster than it is being sent by the black box. I believe it was in 1.4.x that FRS changed how the incoming data from the radio was handled and consequently dramatically lowered the minimum control surface processing speed requirement. I am seeing under 10% CPU utilization.

Something to consider.

Was not considering the display other then the fact of size/space to work with, with FLEX I'm not limited, this I would be... i.e. one monitor, one HDMI port off back
FLEX I can have as may monitors as I wish, provided the PC I build will accommodate them, nothing to do with "speed"

It only stand to reason that the folks that were able to produce an HT that was 20% the cost of their Japanese counterparts by using a few dollar sdr microprocessor would bust into the HF SDR market with the same methodology.. Quality and support will be the differentiators.

The SUNSDR MB-1 is a 4th Generation Direct Sampling SDR in a Box... it's been around for at least 2 years.. I played with their demo units at Friedrichshafen 2014/2015. very nice compact design..   It has a built in i5 Windows 8 Computer inside the box.   But only 2 receivers

I agree with Barry.. it's what the IC-7300 should have been to be competitive with even the Flex.6300.

Their purchase experience requires US $500 cash up front before they build one for you (so much for the Flex deposit for Maestro complaints)...

Software was nice but I preferred SSDR.. probably because I am more familiar with SSDR

Price point US$5,895 near a 6700 but nowhere the near the performance of the 6700.

Brochure is at http://media.sunsdr.eu/2015/06/MB1.pdf

Overpriced Chinese Junk.  (the chinese are starting to get wise on pricing lately)   I am happy with my Flex.
