IC7300

I have just bought a new IC7300, really just for curiosity.

I am now selling an IC7300...

There is no doubt it is very good value for money if you want an SDR with knobs.

The recovered SSB audio is excellent

The transmit audio is outstanding even with the fist mic supplied (FlexRadio take note...)

Its a very quiet radio until you get into the real weak signals and it is in this area that you quickly see, that it is not in the same class as the 6700. But then that's what we should expect and are happy to pay the money for in the Flex, plus a host of other things.

Will be interesting to see what Yaesu do in response.

Thanks for your review Peter.  I was curious about the 7300's performance (although not curious enough to buy one).  Since I bought my 6700 my ICOM 7800 doesn't get turned on anymore.  I really should see about selling it.

I am interested in how it is remoted. Does one need a local client computer and a CIV cable or is it remotable over Ethernet? If it is remotable, does it include IQ data for panoramic display on the client computer? Can it be remoted over a WAN? If so, what is remotable?

I, too, thought of purchasing also just out of "curiosity"...I decided against it R/T the fact that the radio has only USB interface & CIV.  I thought that Icom really blew it with this radio!  It could have been a success with LAN/ethernet...USB was a really dumb choice also w/o any method for external display of the panoramic display, as least not right now...However, I have the best, Flex-6700!  de W3DCB  Daniel

Not sure how owning the 7300 for such a short time can be a good review of this radio. Also how can you compare a $1500 radio to a $7500 radio. Don't discount this radio yet.

Similarly, 'real weak signal work', would that be sub noise floor, EME, or a 4 by 4 dx station in the South Pacific? Sounds like a great review vs the 'nothing can ever beat a Flex, ever' bashing so often heard on this forum. I concur on the flaw in comparing a $1500 anything to a $7500 anything. It's priced comparably to a Maestro and is a complete radio. Somebody, I think it was Sal, commented on its remoting and, to my recollection, yes it can via the ICOM remoting software. On second thought,, it might have been Barry.

Hi Steve, I have been reviewing radios for nearly 50 years, you get to know how it is very quickly.

There is no problem comparing Ford to Audi, its just sometimes the contrast is not as wide as you might expect and you might be pleasantly surprised.

Icom are not stupid, if you want all the extra bits like LAN/Ethernet and external HDMI display, then you wait and buy the next generation of the 7700/7800 etc.

Thanks for your comments

Peter I think the things you said are ok, to me. What you said was, Good value for the money, SSB is very good. supplied mic worked good, things get noisy with weak signals. As I read it I think you were using the 6700 as the benchmark that's all. I don't know what the others are going on about,,,lol

It seems that there is a bit of inacurate information in this thread. Download the RS-BA1 Icom Remote software brochure using the link below to learn how it displays the spectrum & waterfall from a 7300 on your PC & allows WAN remote control of the 7300.

You are correct...I forgot the software display/remote control software which I use with my 7800s...My point was more regarding the use of USB interfacing.  I do not know the cost of manufacture...But, it would seem that for just a few extra dollars, an LAN interface would have made the 7300 radio a home-run.  Thus far, USB LAN servers are not very good and LAN/ethernet access is the future.  USB is generally not used in the business/commercial/industrial world or applications for good reason.  USB plugs wear out with repeated use (It doesn't take much repeated use either!...I have several computers that I use for work which I bring with me to several satellite offices.  I went w/wireless USB devices in order to avoid having to repeatedly plug & unplug USB head-sets, etc., for dictation of medical notes, etc., as these plugs wear out after just a few weeks and require replacement.  I now "permanently" plug in a wire-less USB device/connection and leave them to avoid this.) just to mention only one draw-back to USB...A USB plug is essentially a small piece of circuit board with a few foil pads making contact with a spring-loaded contact against the foil pads.  USB is considered a home-grade device, not an industrial or commecrcial-grade device which is why Serial is still used in industry & business, although ethernet/LAN interfacing is quickly replacing serial interfacing.  Eltima sells a remote USB Server application to make USB devices accessible via the LAN to other computers in the LAN.  The lic. is VERY expensive, however, and in the end the application does not work with this type of device...It is fine for printer data or drives, but not much else.  The inclusion of an LAN interface would have made this radio a real hit for the money.  I do not believe that it would have added more than a few dollars to the cost.  Lets face it, the 7300 is a hobby-grade radio and not in the same league as my Flex-6700.  However, the price is quite reasonable for what is received!  Never-the-less, my point was only that ethernet/LAN would have made this radio a true hit.  Just my opinion.  I may be proved wrong!  de W3DCB Daniel  73!

First, this IS a hobby, not a commercial or defense department mission critical application. I believe, since I do not have one, the USB is used for the same purpose Elecraft uses it on the K3s, read it in brochure, that is as a single conduit for audio (digital audio for the digital mode software running on the PC, as well as command and control to/from software on the PC. As for the sturdiness of USB, have you taken a close look at an RJ-45? Me thinks thou protest too much. As for same league, it's a fraction of the price, not built in the US by US workers. Not made in Austin TX. Of course it's not in the same league, nobody is claiming it is. But resorting to USB connectors vs RJ-45 connectors is really struggling to convince yourself they aren't in the same league.

Even when one man will so endeavor to be detailed & specific in his written or spoken communications, be it just an on-line post about ham radio hobby or regarding something of great import, few seem to understand what is actually said or written...Most of what I just typed was repeated in your response to me...just re-stated in a challenging straw-man style...It illustrates just how difficult it is for us human beings to communicate with one another.  In my area of work, medicine, we try to encourage (read strongly insist, LOL!) that patients come in to the office for follow-up appointments; even when it is "just" or "merely" (from many patients' point of view) to review lab data, etc.  So many will believe that the oft resented follow-up appointment is only an unnecessary inconvenience scheduled to make an extra buck or two, while in truth, these follow-up appointments represent loss to most practices!  However, without that face-to-face communication, very often what is said is entirely misunderstood...This occurs even when there is the opportunity for the face-to-face...so much more so when that opportunity is lost!

It is just fun to peruse & observe the posts & responses from day to day, not just in this forum, but in any area of human endeavor...Most people talk past each other.  A common method of human communications is to set up the straw-man argument of the obvious premise, most of which is likely accepted by both parties, but worded in such a manor that seems to demonstrate that the other fellow disagrees, and then argue against the other fellow for not accepting the obvious!  Many times people, me included, will post and be answered with this technique.  I am certainly guilty myself, although I try to be on a sharp lookout for It...It is, however, a fun study of human communications & behavior...This is not a critical remark, just an observation of how difficult it seems for us imperfect humans to communicate with each other...even when we speak the same language and arrive with similar skill-sets & perspective...It is always fun to observe just how little we actually hear each other.  73 OM de W3DCB  Daniel

An audio or video recording showing the A/B comparison of the IC-7300 vs Flex 6K tuned to the same weak signal would be very helpful.  I don't necessarily think the radios should differ that much in this performance respect.  Were the gain setups optimized on both radios  (AGC, preamp, etc) and similar passband adjustment?

MDS is a good measurement but my experience is that some rigs render weak signals more readable than others independent of their MDS measurement.  In other words, I might hear a weak SSB signal on two radios but the actual speech is clearly more understandable on one of the radios.

I, certainly, don't know where it would land. I think what sort of goes on in my head, sort of floats around, is the notion of 'good enough' . I've pretty much disabused myself of the notion hams are cheap. I think a healthy percentage will pay inordinate sums of money for bragging rites, the $14,000 transceiver pushing a $300 antenna using rg58 vs. the $1600 transceiver pushing a 5-ele mono feed by rg8 or rg213 at 55'.
Some of the comments in this thread are ever so interesting.

Well, comparing a nice Flex 6700 to an Icom IC-7300 is an apples to oranges comparison, IMHO. For instance, in my particular case, I will be mounting my IC-7300 in my Merc G550 SUV, using either the Icom AH-740 or AH-760 autocoupler antenna systems, I own both antenna sysytems, and plan to see which one performs better in a mobile environment. Not really very realistic to stick a Flex 6700, a PC, and a monitor screen into my G550. BTW, as to "comparisons," my brother owns a 6700, as well as an IC-7850, plus he should be receiving his IC-7300 tomorrow, when UPS arrives. He plans to do an A/B/C comparison, albeit he is the first to admit this is an "unfair" test!

JM2C, IMHO, and YMMV!

Larry, would love to see a photo or two of the IC-7300 mounted in your MB. Most cars nowadays don't have enough space to mount anything without a remote head. The G550 is out of my price range, but it would still be interesting to see how the rig fits.

I spoke with 2 different Hams that had just gotten their 7300s on the air this past weekend. Factory mic..... factory settings and the audio was GREAT from both stations... IMO this is going to be a boost to the overall interest in SDR in general. I see that a a good thing.

My brother and I also received our 7300's last Friday, and we can both attest to the outstanding performance of this inexpensive little gem. $ for $, I don't see how it can be beat, by anyone, at this point (Hello, Kenwood and Yaesu? Wakeup, please!). Jim owns an Icom 7851, Flex 6700, and now the 7300. I was about to pull the trigger on a nice 6700, but comparing $9k to $1.5k? I think we are experiencing a huge shift in ham radio competition here. No, the 7300 ain't no outstanding Flex 6700, but I can think of a few other things to do with the spare $7k+ saved, like a new antenna, amplifier, oil change on my G550, etc. I love the Flex. But wow, as Icom launches additional SDR's in their uplifted series, as things progress, and prices them accordingly, it will be great. As Jim mentioned, it is very handy not having to fool with the mess of running a PC to play ham radio. Everything is fully self contained in the 7300 (except for the PS-126 switcher, of course). As The Donald might utter, this is simply called the "Economics of Beautiful Capitalism!"


PS - Sorry to stray from pure Flex subjects, but this little box is a true SDR breakthrough, at least in so far as price/performance ratios!

SDR's are phasing radios.  Phasing radios always sound great.  I almost pulled the trigger on one of these but after looking at the design concept I decided it's pretty much my IC-735 with software innards and good fiters... and after a week I would never turn it on, just like my IC-735.  I think Icom is going to sell a bunch of these, which will whet the apatite to move further up the SDR food chain.

Larry forgetting the fact that the 7300's display is small, even if it were bigger, I do not think the 7300 has the ability to produce two pans of two separate bands. So apples to apples two 7300s would be required to compete with a single 6300. So that is $3000 versus $2500 for a single flex. Plus it may just take two 7300 to equal the performance of a single 6300. Well at least icom is trying.

As I previously mentioned, my 7300 will soon be permanently mounted in my SUV. A lot nicer option that will replace my 7100 (as much as I like the latter, too). We'll see what The Boys at Icom do, as the 7851/50 gets replaced with their high end SDR venture. To some degree, the 7300 is throw away technology, allowing one to hold off a bit for the best. With no PC required, of course. I have used the 6700 extensively, and I just can't get over the hump of needing a PC. OK for some, but not everyone.

I would suppose if your putting the radio in an SUV or something, or taking it were a PC would not work so well, tethering to a computer is not so good. But a computer is just another peace to the shack now days. Many use digital communications, so a computer is needed for logging and many other digital software. Having SSDR running on a computer is never a thought.

Even with the 7300 or an upscale SDR without the need for a computer, what do you run all the 3rd party software on. Digital modes?

I think we are starting to beat a dead horse here, with something that is really a matter of personal choice/opinion.

While I expressed my personal dislike to have to be tethered to a PC to run an HF SDR radio, some folks are coming back expressing why my personal opinion is bunk, by their personal way of thinking, and in their personal opinion. The mandatory need for the use of an external PC to operate an SDR radio, vs/ operating an SDR rig with knobs and buttons, sans any need for an external PC, is an extremly personal matter and choice, so one really can't declare "edicts" on this.

For me personally, I don't like to have to run a PC to use my Ham radio. I talk to guys all the time on dstar who are using ID-51's 5 feet away from their raspberry pie, tethered to their 4G LTE cell phone. If this is the case, why not just make a full duplex, clear as a bell cell phone call, with no minutes of use charges for mobile-to-mobile chats (e.g., as Bernie would say, "free"), or better yet, use Facetime on one's iPhone with video?

Please, now, no flames.

JM2C, IMHO, and YMMDV!

Precisely.  In this day and age, the question is not, "why be tied to the computer", but "why not embrace it to the max?"  If I want to feel nostalgic, I can take one of my QRP rigs out on the deck with my little portable antenna and make a couple of QSOs, like I do at our northwoods cabin, but they're not likely to count toward any DXCC Challenge points.  I'm looking forward to my Maestro and WAN so I can be serious about radio in the middle of the Chippewa National Forest!

The 7300's I am hearing on the air sound FB and the owners seem quite pleased. Listen up on 14.178 Mhz and you might hear a few. One ham was comparing the 7300 with his 6300 and they both sounded excellent. He was getting better reports with his 7300 and no one was complaining about the pricing.

What Lee was pointing out, both Flex 6k and late comer icom utilize a processor inside the radio to run the software of the SDR. Most modern day hams enjoy utilizing a PC for CAT control of their rig. I imagine even the 7300 owner will pine for the ability of CAT control of their rig with a PC. Flex, imho, made the right move and did in-house CAT control of their rig with SSDR. This is value added for me. Going retro with knob control of SDR adds no value for me. For some however, knobs are hard to let go of.

Mike, they have that! The 7300 works fine with icons remoting software. On the other issue, you're both right. I, too, think that's what Lee was alluding to but the 7300 has an FPGA controlling program as well as software to create the pan, service interrupts from the rocker switches and tuning knob etc, just like Maestro. But instead of requiring separate software to control the physical UI, it's all in one chassis.

There is a dealer in North Texas, Main Trading Company that was selling the 7300 for $1,399.00 at the Belton, Texas hamfest this weekend. He sold out all that he brought and told me that he would sell me one at that price if I called him this week. So, there must be a fairly decent margin for him to sell them at $100 off list price already.

Walt ,correct. Some ops seem to be hung up on knobs or a fear of utilizing a pc to control their rig yet love when wjst-x controls their rig to operate jt65. How can I possibly operate jt65 w/o a knob ? Oh wait jt65 software renders the knob obsolete.

 My only concern with adc's and rig based SDR processing is a paradigm shift in adc design rendering present day adc's obsolete or running out of rig based processing power. So far so good.

The 7300 clearly has a computer,  its likely a cheap tablet and it likely controls the radio.  This is my point regarding education, you need some.  Whether the computer resides inside or outside of the box is merely cosmetic.  Flex pioneered the all in one with the Flex 5000C 

http://rigreference.com/en/rig/4485-FlexRadio_FLEX_5000C

The horse power of the computer in this radio was rather diminutive and this was the problem and will likely prove to be the problem with something like the 7300.  Like with a Yugo, you can't improve it's horsepower.  Once it runs out of steam it runs out of steam.  This is not trivial.  Ten Tec made a rig called the Orion and it had a DSP that ran out of memory as features were added, and the TT users were nothing if not feature hungry ( I was one of them).  Once the memory was gone NO MORE FEATURES even though TT continued to promise features would be coming real soon.  Every time they tried to add a feature something elsewhere would break.   That was the day I sold the Orion before it's value plummeted and bought a SDR-1000.  You can see where Ten Tec is today.
