I wouldn't say so.
It fits perfectly the basical needs to work a split. It has 100 watt, internal tuner, touch screen and external monitor.
If it will cost 3000$ it will be far cheaper than 6300 plus a Maestro.

Good refurb 6300 from flex not a scratch and works perfect with 2 year warranty for 2200.  No way I need or want a Maestro....too retro.   hi hi

the spec says it uses the same sdr rx tech as the smaller 7300so I assume its sdr and has a lan socket on the rear panel. once bitten by ic7400 twice why - I wouldnt touch one until there were a lot in the field and over 12 months in use.  Time for yaesu to catch up and replaced the ftdx5000 with something sdr based?

As you all know, Flex was taken to task by a few folks for not having Pre distortion. Why is there nothing said about the Icoms not having it?

No regrets with my 7300. I had considered holding fire until the official release of this rig, but no point based on inside info.

I would be very, very surprised if Yaesu and Kenwood are doing nothing SDR-wise. I reckon that they are just holding back on some final design decisions so they can learn from everybody else's mistakes or to trump them in the tech specs dept.

Bet the IC-7610 has he same 1 Preselect Filter for Two Bands as the IC-7300 to save cost.
The OVF problem to adjacent bands problem will still be there in the typical ICOM style.

Scattered thoughts:

Yaesu and Kenwood may have decided to target chronologically/intellectually "old" hams who insist on buying large, heavy, expensive analog  radios. 

A few things we Flex users might learn from Icom are (1) How to eliminate latency in an SDR.  My 7300 seems to have little/none compared to my 6300+I7 computer.  (2) How to make an SDR that is more RF-proof.  My 7300 survives very well in less-than-ideal environments where there is lots of stray RF while my 6300 does not.

Technology and performance aside, I'll stick with Flex Radio Systems because of their second to none customer/technical support.  Icom would probably never allocate the resources and talent to match what Flex does to make their customers successful and happy.

Icom achieves lower latency at the expense of filter shape. But don't assume this is a permanent comparison. Anything software defined can be changed dramatically and relatively quickly with new programming.

Remember, the first ARRL review dinged the 6000's CW note and side bands. A new software release and the CW note was perfect.

The Flex6500/6700 is Front End RF bullet proof since it has the Individual Band PreSelectors compared to the 6300 and the ICOM 7610/ICOM 7300

Chaps, this place has become like some of the supercar forums that exist.  On these they insist on poo-pooing the opposition as their car can only go 159mph instead of the 161mph of the forum's favourite. Such comparisons are meaningless, unless one has an ideally located QTH, a quiet QTH and perfectly located and tuned antennas. Who does?

My British Leyland TR-7 was run up to 135 MPH on Dulles Access RD in '78. Plenty of gas pedal left but 135mph a mere few inches off the road drove my adrenaline OVL so even though I could have punched it,I graciously declined to press my luck. It was legacy analog, no computer to freeze up. And, as it happens, I lived to tell y'all about it. ...OR, I didn't and everything since that night has been a consequence of being on the other side.

Walt, too funny.  I always start thinking about KE=1/2mv^2 and what that means to bearings, tires, tie rods and such, plus if I hit a turtle it's airborne for sure

A word of caution to all.  Please keep this thread factual and refrain from goading anyone about what might or might not be and comparing mine against yours.  We will shut the tread down if it moves outside the Community guidelines.

Here are a few the facts as they appear:
  1. ICOM has not said the 7610 is or is not a direct sampling radio.  That was not true when they announced the 7300 where they made a huge deal of that fact - calling it "revolutionary."
  2. ICOM does not call the 7300 a SDR in any literature I have ever seen.  The 7300 is an IC-7100 (per the the 7300 service manual) with a DDC direct sampling front end driving the 7100 DSP chip at the 24 kHz IF.  You won't find them saying it is a SDR in their literature, web page, or manual that I can find.  There is a big difference between sDR and SDR IMHO.
  3. If you watch the video, you can see that spectrum/waterfall performance looks almost identical in performance to the IC-7851.
  4. If you look at the video of the back of the radio you can see that many of the holes in the back panel are empty with no connectors installed.  Appearance would say that the CPU and display are operational in static demo mode.  There are clearly boards missing and virtually no specifications other than dual watch, HF-6m, and an external HDMI display output.
  5. All else is speculation until they say more.  
Competition is not a bad thing.  Let's see what this thing is when it becomes real or they give some real specifications.

73,
Gerald

No way to compare 7600 with any combination Flex6X00+Maestro, 7610 just successor of 7600

Gerald,
   
   Agree with you, Your QEX articles on SDR radio's should be read so that one 
understands, that not all radio's are created equal !

Hope the group reads these articles, then they may understand what SDR means.

https://www.flexradio.com/downloads/sdr_qex_3-pdf/

https://www.flexradio.com/downloads/sdr_qex_4-pdf/

Thus comparing, this radio to that radio can be misleading

Perhaps it is just me ... but Amateur Radio was so much more fun and engaging when the discussions were more centered around communicating with others and sharing with other cultures, and less about negligible improvements in third-order intercept and millisecond latency differences, or the color of the S-meter. 

I get it .. but each time a new radio surfaces it seems pointless to automatically go on the defense to best justify your expenditure. My wife and I are art history enthusiasts and travel the world looking at art and drinking fine wines. We recently went on a wine tour in St. Emilion outside of Bordeaux, France where each sip was so overly analyzed, dissected, compared ... I just wanted to yell 'now swallow the darn swill'. Someone once told us Van Gogh used too many paint strokes. Seeing 'The Starry Night Over the Rhone', standing next to the painting in Paris, you will not think so. Breathtaking. I feel the same way here .. 'just call CQ and take joy in someone answering your call'.

I am sure ALL these radios will benefit the discerning amateur, within most any context, and afford enjoyment and hopefully new challenges, as we grow as Amateur Radio operators.

Beauty is in the eye of the beholder. Hi Hi

I personally love comparing the esoterica of Radios and Fine wines. Spend a lot of time in France doing just that. Went to LE GRANDE TASTING in Paris Lat year where they tasted 2,800 wines. Also went to a lot if Hamfests where I compared radio specs and got allot of free drinks in the process.

By contrast I have no interest whatsoever in seeing those Van Gogh even though we live part of the year in Provence

I recall a similar debate on here when the 7300 was announced. I managed back then to find a link to a generic definition of SDR which was published by a well respected professional group. As such, I suggest this definition is more credible than many:

Perhaps a wider definition than some would like ;)
