The IC-7300 received FCC approval today, now to figure out the street price.

The latest info I have on this radio, is that if it is used with the USB connection to the PC, and that PC is running ICOM's RS-BA1 software, the spectrum scope, and a control panel can be displayed on the monitor. Full control, full audio functions thru the PC sound card. It's also remote able over IP.
There is a small amount of latency between what displays on the radio screen, and the same signal showing on the PC monitor.
All this we have learned by watching a Japanese ham posted on his YouTube Vblog about the 7300.
Sorry, I don't recall the address. Just do a search.

If this is true then it will be a good start for the predicted price point. The latency between the screen and the PC will be irrelevant if you blank out or do not display the radio to your view. Then you will not notice any latency issues.

Are there any screenshots available out there of the Icom software? I have never seen it in action before. It might already be out for other things but I am not aware of it.

Thanks for these updates

"Sorry, I don't recall the address. Just do a search. "

Haven't been able to find anything showing the RS-BA1 on the IC-7300. Would be interesting to see. Too bad we don't have a link to the alleged video...

$1499... http://qrznow.com/icom-ic-7300-launch-price-usa/ [nice video]

From what I've learned it direct samples then downconverts in firmware to ~32khz IF and uses ICOM's existing DSP hardware/firmware from previous radios. It looks like the screen operations are about as complex as my Android phone actually...

Cheers!

Yeah the more information that is released about this radio the less impressed I am with it. I am sure ICOM will sell quite a few of these but thus far I think it was rushed to the production floor... You taking notes Yaesu?? I hope so!

That is not really different than any other modern radio.   Seems like just has a faster processor for the screen display.

From the spec sheet that I downloaded, you are not correct. The 7300 uses a direct sampling system where the A/D converter operates at the operating frequency. It's antenna - bandpass filter - A/D converter. Everything from there on is digital.

My interpretation is you are both right. The front end is straight into an ADC, then an FPGA digitally downconverts to an IF frequency in a manner that allows them to plug the resulting data stream into their existing DSP code.

This isn't quite the dream rig architecture people want, but it makes for a conservative first step into a full SDR for ICOM. Doesn't allow for large and multiple "slices" ala Flexradio.

Then we find Icom breaks the basic SDR direct sampling design.

Un-calibrated  waterfall and S-meter and a transmitter that has all the design failures of the legacy transmitters. ALC  overshoot, a PA with power spikes and poor IMD. Then we have to see if they have a noise transmitter than generates wide band noise and other spurious products. I wont be holding my breath when it comes to a new Icom radio model.

So the supposed advantages of a new technology platform are locked away and dripped out  for their profit model. The end results is products that are crap radios with crippled features.

At least if you buy  a current model Flexradio or an Anan radio you getting the full potential of the technology at a bargain price. The Japanese  manufacturers just dont want to get it or they too arrogant to listen. Hams want better radios not crippled radios with design flaws. Besides why should we be fund their R&D market testing program when the market has already decided what  capabilities the technology can  deliver. Icom wants to take us backwards with their vision, yet the future  is already available. And really if the radio is just another glorified IC718 with no performance improvements in transmitter and receiver performance who cares?

Icom needs to get into the business of delivering state of the art products not crippled products designed to milk hams over decades with incremental and little improvements.

I just figure this "baby" step allows Icom to use their existing DSP code, existing RS-BA1 remote software, etc, with minimal changes - without as much of a risk as a full featured transceiver.

Do you want this now, or the fancy model 2 years from now after all the new code is debugged? Hopefully they're working on the full size, full featured rig now.

The 7300 doesn't look too bad for a rig that is small enough to take field day portable, yet reasonable featured enough to use at home - at the TS-590SG price point. I hope it lives up to the initial hype.

jeez, whatever... I think I said it direct samples, that denotates "at the operating frequency". I described "everything from there on is digital" as being ICOM's existing DSP stuff. Appliance ops can have this thing, more power to 'em.

I was initially put off by the seemingly kludgy design of this radio but I thought about it some more and am thinking that probably it will be quite good. Replacing the usual analog converter and interim IF's with direct sampling and firmware downconversion presents no problems at all, probably that is the main basic advantage to direct sampling/DSP, no? The interface seems to be as simple to operate as a tablet and that is a good thing. The DSP at the last [and only] IF is tried and true tech... I'm starting to feel that this radio could be a great one. People are pre-ordering already, we'll find out soon enough.

Have you actually tested one of these ?

The question is: are there proof that you have full computer control? ADC signal to and from computer?  If so, then in a worst case scenario it's a cheap Flex 6K with maestro for 1\3 price. Else, it depends on what it can do.
We know it doesn't have advanced features that cna be found in much more expensive radios, but for the price... It's a far better radio than the competition, even if it doesn't have ADC to\from computer :)
