Excellent Radio and Company  Time owned: 0 to 3 months
First off I traded my F5000 with FlexRadio's program. They offered a price within a couple of hundred that I figured to net on the open market. Trading relieved me of worries about scams, shipping etc. So it worked for me.

I have had the 6300 for a couple of weeks and I find it to be much higher performance than my 5000. Mostly I chase CW DX and the 6300 meets all of my expectations. Software installation and setup went very smoothly and maybe took 30 minutes. No bumps or issues. The F5000 is an outstanding radio to be sure - no complaints except for the load on my computer.

The 6300 uses much less CPU time. So far no hiccups. None on a W10x64, AMD A10.

I have read some comments from hams complaining about the wideband noise blanker. Well, it works for me - followed the information in the software manual. The setting of AGC-T and the WNB both need to be used.

Some have noted the absence of preselector filters. I was concerned. No need. For me this has proven to be a non issue.

My experience with Flex throughout the transaction was uniformly excellent. From the initial discussions with sales to the receipt of my trade credit, each step was very professional and business like.

That's my two cents worth.

Great!!!  Time owned: 0 to 3 months
I sold my Yaesu FTdx5000MP after 3 years and bought a Flex6300. I am very happy with this transceiver,no regrets that I sold the Yaesu. I also bought the Maestro and I am now QRV in the livingroom and garden and also use the IOS app for my Iphone and Ipad.
Great receiver and a lot of settings that makes using the TRX very good. I am using the latest beta software and have no poblems at all.

Good Radio  Time owned: 0 to 3 months
I swore off SDR transceivers about a year and half ago, or so I thought. I went thru a brief interlude of insanity and purchased a Flex 6300 in April 16.

I think the Flex concept has matured somewhat since I sold my 5000a. Instead of a "fat pipe" to the computer, the heavy processing is done inside the box. The computer/radio interface is very stable and not prone to RF like the firewire type of yore.

For the most part, I'm pleased. Myself and others have issues with the radio acquiring an IP address from routers and wifi extenders on first power up. A solution is to leave the radio on at all times.

just brillant  Time owned: more than 12 months
Obschon auch der Flex 6300 nicht perfekt ist - nichts ist perfekt - erhält er doch eine glatte 5 als Bewertung.

Als erstes SDR Radio kaufte ich mir einen Flex 1500 und fand sogleich Gefallen daran. Ich entschied mich umgehend auf den 6300er zu setzen und habe ich nach 2 Wochen überlegen gekauft - und nie bereut!

Ich besitze diverse Radios aus verschiedenen Dekaden und sowohl Einsteigergeräte als auch Premiumteile.

Der Flex 6300 ist ein tolles Gerät mit einem ausgezeichneten Empfänger, selbst an meinen "grossen" Drähten und am Beam bin ich bisher nie in den Hammer gelaufen. Andere zeigen da schon mal Beschwerden.

Ich verwende ihn ausschliesslich für SSB, Transverterbetrieb und für DIGI modes. CW beherrsche ich leider (noch) nicht und kann dazu nichts sagen.

Die unsäglichen Foren beachte ich nicht, ebensowenig wie das teilweise dumme, sektiererische Geschwätz auf den Bändern - in Bezug auf Model- Marketing- und Kommunikationspolitik von FlexRadio. (Ihr wisst schon: Predistortion........)

Es wird interessant sein wohin die Reise führt, ich habe den Flex Zug bestiegen, lasse mich überraschen und geniesse die bisher völlig störungsfreie Fahrt.

Just fell in love!

FLEX keeps improving  Time owned: 0 to 3 months
While doing some research on the internet I noticed the popularity of SDR transceivers increasing. I've been on HF since 2007 and have owned an Icom 706 and a couple of Kenwood (TS-530S, TS2000, TS-480 HX). I took a chance and bought a Flex-3000 on eBay.

Using a SDR for me was opening up a completely new dimension. It's comparable to driving a stick shift car, and then going to an automatic over night. The Flex-3000 software (PowerSDR) does require a desktop/laptop with some muscle. The computer should not be clogged up with numerous software programs, and it has to have a fire wire port. Provide all this and you are good to go. Once I started using the Flex, I only kept my other radios for "backup" purposes. SDR has totally changed my operating.

5 years later, I notice that Flex has a program to turn in your older Flex for the newer Flex 6XXX series. I thought their offer for my old Flex (as a trade in) was fair so I decided to order the Flex-6300. It's a total gas. The rig and software (SmartSDR) connects to your computer, or router (LAN) and uses your desktop/wireless laptop to control the rig. I do not use the mic that came with the rig, as I use my computer headphones/mic. This inclusiveness has now left me spoiled as everything is done through the desktop. I's great that Amateur radio is actually catching up to the 21st century. SDRs are not for everyone. Some folks are staying with their tube radios, where the audio quality still can't be matched. My audio reports for my TS-530S have always been the best. To each his own. The Flex-6000 allows you the chance to get right on frequency, and to experiment with the different settings with the software. The system is not perfect, however. There is a great support community on the Flex web site that has helped me some some fairly simple issues. For example. Out of the box I could not get the rig to talk to my router/desktop. Turned out to be my ESET security firewall. I just configured it to let the radio through and wham. Also, there seems to be an issue with transit audio on SSB that makes an echo sound. We are still working to figure this one out.

The folks at Flex were very helpful during the sale. It's only been about a month. So, I have not had to contact them directly for support. Been just using their online support system.

What did I do with the Flex-3000? Well ... I haven't sent it back to flex just yet. Give me time. 73 KH6DAN

Amazing radio  Time owned: more than 12 months
I have had just about every series of Flex radio up to the 6300. I have also used most current HF rig by every vender (ok, I have a radio problem). While all radios do a darn good job, the 6000 series take it one step further.

SmartSDR has the ability to process weak signals noise so much better than your 'normal' radio. SmartSDR and a 6000 series also includes Controlled Envelope SSB, something that is not found in any other radio. That makes your 100 watts sound more like 200 watts. You can read about it here: Watching the waterfall on SSB transmitting stations, I can now tell who is using a Flex radio. There is that much difference.

Lastly, the service is second to none. Do you think any of the big 3 will actually talk to you on the phone if you have an issue? Flex will actually connect directly to your computer if you want them to should you have any issues. With an SDR radio, you also get a new feature functionality every few months. The big 3 can't touch that. Now, with the addition of the Maestro, your experience only gets better.
Lastly, you don't need to spend a lot on a computer to support it. Any new $300 box from Costco will easily run SmartSDR.

Brilliant performer  Time owned: more than 12 months
I was p'd off by the earlier review.
SDR is so much more interesting, especially as the new radios incorporate knobs as well as displays and pc connectivity.
the one thing I find outstanding about the 6300, Elad FDM duo and the Sunsdr2pro is the almost magic clarity of reception of very weak signals which one can't hear on noisy Icoms etc.
One can do so much more with the modern sdr radio.
that's all I have to say.
Enjoy the enormous flexibility of the new Flex 6000 series.

Great and Getting Better  Time owned: 3 to 6 months
I have a Flex 6300 and am now selling my Icom 7600 as I can't see myself going back to a traditional transceiver. The Flex is a very good radio and is only getting better. I disagree with the prior reviewer. Unlike traditional box radios, this SDR can and is continually being improved and that is not a negative, but a good thing. However, even as-is with smartdsr 1.6.21 version software, it is an amazing unit. There are more things to come, but I see nothing to complain about, at least for the non-contester user, and I've heard good things from those who use the 6300 or the 6700 for contesting. There are no perfect radios, and some hams unfortunately get a lemon unit, but that is the exception and not the rule. SDR is the future of ham radio and I'm happy to be getting in on it now.

Nothing but headaches   Time owned: more than 12 months
I have had both the 6300 and 6500 and I will NEVER buy another one. Sick of all the excuses, delays, revisions, broken deadlines promises. You should not release a product for sale unless it's ready for prime time. Save your money and go get a real radio. I but a Kenwood TS-990S so its not a money thing for me. The company needs to learn how to run a business and not rely on the community to fund their projects and research. Don't put equipment on your web site for sale at full price unless you can deliver! Equipment is good but nothing more then that. If you want a SDR, buy an ANAN

After 1 year in Operation  Time owned: 6 to 12 months
I waited nearly 1 year to write this, so I do have many hours of operation under my belt. I've been a ham for almost 40 years now and I've had many new radios over that time. To mention just a couple. I owned a set of Drake twins and also a Kenwood TS950SDX. Neither of those radios were cheap. I told you all that to give you an idea of my experience as a ham.
The 6300 was my first SDR, and I was nervous about buying it. I did a lot of research and ended up buying the 6300 at Dayton. I got to sit with the engineers there, and ask lots of questions. So, I made my purchase then.
I can honestly say that this is one of the best radios that I have ever operated. The ability it has to get rid of interference and QRM is just amazing. Even when there is a signal that is right in your operating bandwidth, I am, most times, able to get rid of it.
The sensitivity of the receiver is great, and even with my meager antenna system I can usually pull out the weak ones. (I use a Hexbeam at 35 ft)
I am constantly told that my audio is outstanding. I use no outside compression or equalization, but only what the radio provides.
It is hard to go into each facet of the radio and explain some of the things you can do. I will say this though. This has been a great radio, and I don't think I could ever go back to a traditional style radio.
I love the fact that I can look at the entire band at one time, or 2 different bands. I like that I can look at individual signals and be able to break them down
I really have nothing negative to say about it. I guess if you wanted to, you could nit pick any radio.
I'm happy with mine. All my friends that I have shown it to have all been really impressed. If you thinking of buying one, what are you waiting for?
