    Brad, before you order the 7610, you might want to peruse the user manual.  ICOM makes fine radios (I have 3), but like any radio, it has shortcomings, and you might find that it lacks other features that may be important to you.  That’s why I opted for a Flex instead of the ICOM.   

    BTW, my first “radio” was a brand new Hallicrafters S-120, followed by a Heathkit HW-16 rig, so I guess that qualifies me an “expert” in old age too!  (-:

    It would be a real bummer to "move on to an Icom" and then find out that its "independent receivers" are the same as the 6400M.  For every transceiver I've ever owned, the "second independent receiver" was not really a stand-alone separate receiver -- it was only good for listening using the same antenna and usually on the same band.  My FT-1000MP MarkV, which was near-top of the line when I bought it (back when dinosaurs roamed the earth) was like that.

    To be fair to the 7610, it does have two ADCs, albeit I believe they are not quite equivalent to each other. The whole conversation about heat sinks on the 7610 ADCs clearly indicated two of them. And the 6400/6600 are also not free from heat sink issues. Both Flex and Icom make good radios, but none are perfect.

    As usual, Ken arrives as the voice of reason.  That, along with his technical knowledge, excellent writing skills, and ability to make a complex subject easier to understand, makes him more than worthy of the title "Elmer."

    As a ham of 54 years (read that "old man") and Flex owner since 2010 (Flex 5000 to 6300 to 6600 in 2018), I experienced no difficulty understanding the difference between 1 and 2 SCU radios or the front end/filtering differences between all models.  Now, I'm all for extending grace but I take minor exception to folks accusing Flex Radio with misrepresenting their products.  The product comparison table states that the 6300 and 6500 radios are single SCU and incapable of full duplex or diversity reception.  The 6600 and 6700 are capable on both counts.  More importantly, if a person is unhappy with his/her purchase decision, they DO have 30 days to return or upgrade the product.  Do I-K-Y do that?  When I consider how patient and kind Flex guys were to newbies like me, whether over the phone or at hamfests, I have difficulty hearing them accused of misrepresentation.

    Based on the length of this thread and the number of folks who have weighed in, I think it's fair to say this is NOT a black and white issue.  Ken NM9P had the most sober assessment of the different angles.  To be clear, I never said that Flex had hoodwinked me or misrepresented its product.  What I did say was that Flex used language that was misleading to anyone without an intimate knowledge of the architecture of SD radios.   And I stand by that position, feeling that Flex should share some of the burden of ushering in a new age of radio by helping folks, old and young, understand what they are buying.  If they attach new meanings to old words, this should be clearly explained.

    Anyway, I've changed my mind and decided to keep the 6400.  It's not even remotely worth an extra $2k to add 6 meter receive capability.  I have my old Icom 756PRO collecting dust, so I'll interface it with the computer and monitor 6 meters while using the 6400 that way.  I am truly grateful for all the comments, and I guess I'm (slightly) smarter than I was yesterday....

    Brad,  I think you will find, as I did with my 6500, that you have purchased an excellent rig.  Although there is a bit of a learning curve, once you master the panadapter, the settings for AGC-T, and Mic Profiles, you will be amazed at its performance, in spite of the initial letdown of expectations regarding the definition of the receiver(s).

    I wouldn't be without my 6500, unless it was to upgrade to the 6600 some day in the not to distant future.

    Good luck, and as I can be helpful, please contact me.

    OM I am a new 6400M owner/user and I have been totally loving the rig.  I am pretty sure that you will too.

    If you just want to montor 50 MHz, why not get a SDR-receiver like the Elad S2, this will allow you to see whats going on, and if there is someting you can quickly switch over to the Flex.
    The S2 covers 0-60 plus FM/Air and 2 meters and then some.

    WOW, things are calming down now, and we have another loyal 6400 Flex Customer!!! Before I decided on my 6600M, I spent an hour on the phone with Flex marketing.. I had my list of questions, and they were all answered.. 8 out of 10 questions were answered with a Thumbs Up, I like that, but two questions did not satisfy my radio operating desires, but they were Far Down my list of must have in my radio needs and one of two might be in a future software release.  I also asked a lot about their manufacturing techniques in Texas, and their QC process etc. etc.  One thing I was VERY EXCITED to hear was that Flex charges $200 to upgrade to a new Higher version of Software!!! So when 3.0 is released, It should have some very exciting features.. And we know that development cost time and labor cost.. If Flex could not recoup some of their cost, then where is the incentive to spend the time in development?? If it all plays out, that $200 will get Flex Owners a Next generation Software Package... In the meantime 2.**** will continue to get minor upgrades and changes For Free!! 

    Thanks Flex

    It has everything to do with it, the receiver in an SDR radio is much much different then a non SDR radio.  So as I said,,if you understand that an SDR radio uses ADCs and SCUs you would know what they are and what they work.

    Robert, I remember Gerald saying that the $200.00 does not even cover the cost of development.

    Your Correct,, So Flex charges a Modest Amount, they probably could charge $1000, but most people will probably Run Away, so $200 seems like a sweet Spot...
