RF Direct sampling system — a first in Amateur Radio*
Instead of the conventional superheterodyne system, the IC-7300 utilizes the RF direct sampling system — a first in an amateur radio transceiver.
Personally I think I'd be contacting Icom and getting them to withdraw that especially given how poor performing the specifications of the Icom 7300 are and how its likely to harm people's views of SDR receiver performance and in turn do harm to potential sales of the Flex 6000.
I wouldn't get carried away dissing the IC-7300 until someone actually tries one, let alone tests its performance.
Generally speaking, we hams only benefit by additional manufacturers bringing direct sampling radios to market and we should welcome them. I hope Yaesu, Kenwood, Elecraft and Ten-Tec join the fray.
The obvious reason that the 7300 has such bottom end specs for a SDR is that Icom is afraid of cannibalizing their more expensive Legacy Radios by having comparable specs to modern SDR's.
I expect that Icom will be very slow in the uptake of high end SDR's to protect their investment in Legacy Radios
And yes they certainly won't cannibalize the models above it at its price point from a overall performance perspective. But you can bet that the follow-on models that will come out above its price point over the next few years will more likely than not also be DDC designs. I think there is very little doubt about that. And there are several models in that lineup that are due for replacement, so I don't think it will be that long. The real question is will those higher-up models also just be traditional radio designs implemented in DDC / SDR? Or will they have capabilities beyond that? Basically those “non-traditional” radio capabilities that we are all familiar with here.
The bottom line is when someone asks me what I think about the 7300 in the context of it being an “DDC SDR”, I factually describe what it is that they have done technically, and have not done. And then explain what that means in terms of its actual performance, capabilities, and limitations as compared to the SDRs that we are all familiar with here because of those design and architecture decisions that they have made for the 7300.
We are kinda glad to see them get a little toe in the water.
If you look at the specs and block diagram it screams profit margin compared to the IC 7600. There is NOTHING cutting edge about this technology. My guess is it will perform about as well as a mid level K3 with a bunch of filters for half the production cost of a mid level K3 with a bunch of filters, i.e. it will be twice as profitable for Icom. This radio is not really so much competition for Flex as much as it's a legacy radio killer. From the specs it looks to
me like a 120mhz ADC, a cheap FPGA, a cheap android or linux tablet and a couple knobs
SDR is about the software and what you can do with the software, not about the hardware. The hardware is already beyond good enough. From the software point of view the 7300 is primitive compared to the 6K Flex series. The 7300 will further open up the SDR market to a greater swath of hamdom and that's a good thing.
Some folks just want to bang out a CQ on their old J-38 and learn something about the person at the other end of the ether.
And God forgive them if they don't auto-log the QSO or feel the need to define themselves by some ethereal 599 report.

You can tell by very specific behavior traits in their posts.
After an amazingly written response by Duane N9DG all SteveJ fixates on was the ripping customers comment from Howard. Duane just broke down into manageable pieces the reasons why the 7300 is perceived as a rip off with a truck load of technical acumen. But that doesn't merit a response from either of our 3 new guests in the forum.
Ken Hansen is clearly offended by the "unsophisticated" adjective, following on the perceived outrage of SteveJ. Very typical trolling technique. Find offense which somehow the trolls think will add gravitas to their posts. Ignore the substance, is all about the cover and not the content.
Then Wilbert Meyers comes in out of nowhere, and bashes the Maestro for being a device with no radio. Wait until he sees the FlexControl, a knob with no radio, or the RadioSport Headset... which, oh my, is an accessory that it is sold with no radio!!.
Do you think they might know each other? Are they even licensed hams... they don't find it necessary to grace us with their call signs. Yet another trait of Trolls... anonymity.
They are also trolls because there is no desire to engage in a technical debate about the equipment, just name calling, trying to insult the community of Flex owners based on the price of the product.... calling posters "Flex fanboys" and trying to plant the seed of dissent and unsophisticated behavior in the forum.
The funniest thing though is some of the arguments. For example, trying to define Icom radio's as the "affordable" alternative for amateur radio ops. I am still laughing about that one. Icom..... affordable.... cheap.... all in the same sentence.
Complaining about the Maestro (an accessory) for not having a radio, but not overly concern about the 7300 trying to be sold as an SDR with.... get this, no SOFTWARE.
But I will bite the troll bait, and argument that, Price is irrelevant. You buy what you want or what you can afford. And that ends the price argument. That "cheap" 7300 will feed a family for a year in some parts of the world. That "expensive" 6700 is the price of a long haul commercial First Class plane ticket for one person.
Hopefully the trolls will realize that we are just not that interested in their approach and go to greener trolling pastures.
I can't wait to find out what specific word or comment in my post they fancy, which word offended them. On the other hand, if they leave to never come back.... I will not miss them.
One antenna port, molex tuner port, Din 13 acc port, 2 RCAs, where have I seen a similar rear panel.......
Icom IC-718 rear panel
Interesting and good observation Sal! But, as I said earlier, we'll all know more by end of July.
The powers to be have shut down other discussions related to Flex much quicker than this nonsense going on here!
My two cents worth...
I do, however, think it is Gerald's, Steve's, Eric's and Lori's job to worry about who is and who is not their competition and may or may not be a threat to their revenue stream. What no one is acknowledging is the subconscious fear people have that the 7351 may directly compete with their radio at a fraction of the price. That may or may not e er happen, so it is the realm of how many angels are dancing on the end of the pin.
This thread has become too funny.......
