Title: Best used High Performance HF Transceiver
Post by: N8FVJ on January 19, 2018, 06:30:45 AM
Your recommendation of best used high performance HF transceiver $900 or less. I believe the TS-590SG that been showing up on QST for $900 is the best bargain out there. Your thoughts?

If you look at the Sherwood list, you'll see that almost all of the rigs rated higher than the '590SG are also higher-priced.

IMHO, the '590SG is the best-bang-for-the-buck, new or used.

Just remember that the "sherwood list" that many suggest as the gospel on rig choice is made in controlled lab conditions and not in real world and nor does it begin to rate or quantify how it sounds, easy of use or ergonomics...

 Kenwood 850, Yaesu 990, Kenwood 870, Ten-Tec Omni VI+. You might be able to find a clean 1000D for $900 or less. The Icom 775 still commands an unreasonably high price and is not that great of radio.  I've personally owned all the above mentioned radios except for the Ten-Tec Omni VI+. Yes, parts can potentially be a challenge if something breaks. Not having to fiddle around with menus is a nice feature for these radios.

I agree with your statement- one has to hear the radio performance, numbers are not everything. However, the TS-590SG is a brilliant design. The DNR is great in the TS-590SG. I bought a Yaesu FT-991A for VHF/UHF long haul SSB use. It replaced my FT-847. The FT-991A DNR is interesting removing almost all noise. But, it is too strong even on lowest sitting number 1. It will not resolve weak signals like the TS-590SG DNR even if it has a little more background noise.

Side by side I have found that the 7300 does much better with weak signals in noise than a 590SG side by side. (I need to try it with a 991A sometime) In still maturing IF DSP world the 590 is a 9 year old design that has only seen minor tweaks in SG version. The 7300 is a lot newer in design. BTW I am a Kenwood guy but for money I feel there are better rigs than a 590 these days.

Kind of depends on what you want to do.  HF only, the Kenwood TS950S and Kenwood TS850SAT are great radios.  The 950 does dual receive and is 150 watts out.  The Yaesu FT1000 is a good radio in this price range also and does dual receive and 200 watts out. 

If you want to do HF and 6m, Icom 756PRO2 has a lot of features.  The Kenwood TS590SG shows pretty good performance.  The Kenwood TS480HX will give you 200 watts out on HF and 100 on 6m.  You can probably find a used Icom 7300 at the top of this price range.  The 590SG (But not the 590S), and the Icom 7300 will let you hook a second radio or receiver to it so you can do true dual receive.

If you want an HF/6m/2m/70cm all mode radio, the Kenwood TS2000 does those nicely, and adds full duplex for satellite operation.  The Icom 7100 is a currently produced radio, and is loaded with features and it can send and decode RTTY without a computer.  The Icom 7000 isn't that good of a radio, I would go with a 7100 or TS2000 instead.

Lowest price IC-7300 is $989 per ebay. Most sell over $1K. But, in time it will be a $900 radio.

Nicely is not the word here, more like marginally as it lacks a lot in HF receiver performance because of it primitive IF DSP design by todays standards. (how many are still using/buying Pentium P4 computers which are about same age as TS2000 design)

Yous should review the schematics of the TS-2000. Then you will understand why they still do so good. They have two DSPs, each 100 MIPS while a Icom 756Pro3 has one DSP with 40 MIPS. And the TS-2000 do use crystal and ceramic filters of different bandwidth which will switch in in the background and do slope tune. They support the DSP. The TS-2000 is a masterpiece in many aspects.

Oh I have read the schematic but even more importantly I have played with/used one several times and it lacks HF receiver performance big time compared to modern DSP rigs and even some analog rigs. Now if they would redo/reboot it as a updated say TS 2100 then it could rate some serious consideration.

Hmmmm.
I've been following your 'postings' ever since you said your 7300 had a "noisy" receiver. Then you bought a 590SG.
Now you are considering both again?

BTW, are you not the chap who said you had "bad ears"?

The TS2000 I have seemed to do better on receive than the Yaesu FT891 was has brand new DSP.  I will admit that I don't understand very much about DSP design.  How would newer, more powerful DSP manifest itself over the TS2000 in operating?  Would the noise reduction be better?  Would the filters have a better shape factor?  Trying to learn as I go along here.  I have had an Icom 7000 and that was rather disappointing.  The 2000 outperformed it.

Modern DSP in same price class has better selectivity and steeper skirts on band-pass too and better image rejection as well. But you get what you pay for too and 7000 did not have very good DSP.

What are you supposed to be "hearing" that receiver performance numbers cant measure?

  This is spurious nonsense spread by hams who dont want to accept the fact that radio engineering is science and every aspect  of this science can be measured.  Over the years I have listened to this so called "on the air" or "ham urban myths" about this radio having mystical performance in one or 2 areas of performance. In all cases when these radio were put under test they were horrible and miserable performing radios.

The only aspect of performance that cant exactly be measured is the performance of the  noise blanker or noise reduction whose performance  varies  because of the huge variability  in noise sources. But even noise blankers  and noise reduction performance can be quantified if someone took the time.

I will leave the "golden ear" testing to the CB'ers  who dont measure one  performance aspect of their radios and change them like stocks just because another cb'er tells them subjectively that its a better radio. This is not where we want ham radio as hobby to go when we practice ignorance, voodoo and radio folklore.

Well if you can "quantify" or tell me what a decent lab cant measure that your ears can I would be willing to give your  golden ear theory a try  and compare some radios.

The 7300's DSP chip is of a newer design than even the one in the FTDX3000 and by comparison it makes the 590's DSP chip look like something out of an 870. I owned a 590 for  year, nice radio but the NB and NR were from 15 years ago no matter how it was adjusted. Then came the FTDX3000 which at least the NBW worked better than the standard NB  plus if you only use a very small amount on the NR it didn't sound like an echo chamber but in the 3K above 20m you should use the 1st Pre Amp cause directly into the mixer it has lower gain then the rest. Along comes the 7300 and properly adjusted NB works like one should, the NR with only a 2 or 3 setting is fantastic, without pre amp is the way to run this radio, it simply does not need it, well maybe on 6 meters but w/o pre amp this is one hot radio so my call would be look for a used 7300 it may be small but packs a punch and the RX is better than most give it credit for. One slick control is the RF gain, it doesn't work like your dad's radio, more like an adjustable attenuation, real slick and it works great plus you can adjust it to exactly what you need per the band and conditions.

The IC-7300 has the best NR I ever used. It reduces noise without any artifacts like that watery sound Kenwood produces at higher settings. However, I used the noise reduction on a Yaesu FT-991A. It is too strong even on the lowest setting. The TS-590SG outperforms the new FT-991A NR on weak signals. If the FTdx-3000 uses the same NR, I would not buy that radio. NR makes a large difference on the noisy bands.

Perhaps Kenwood will be bringing the rumored TS-890 to market soon.

Agreed. Haven't seen any at $1,200 yet, but since the 7610 has been available, folks are virtually "giving away" their 7600's at around $1,500 shipped. This was originally a $4,000 radio that was sold by vendors at $2,000 when a few new leftover discontinued units were still in stock last year. They're all gone now. They're a great full-sized RELIABLE radio...an excellent fully featured performer. I've had mine for seven years with absolutely no issues, even through many contests. I bought a 7300, but gonna still hold on to my 7600...no desire for a 7610.

IMO, a clean used 7600 *should* be selling for closer to $2,000 at this point, so if you can find one at that $1.2-$1.5K price, you can't go wrong.

Well if you can "quantify" or tell me what a decent lab cant measure that your ears can I would be willing to give your  golden ear theory a try  and compare some radios.

I ACCEPT YOUR CHALLENGE.  PLEASE ARRANGE TO DROP BY SO THAT WE CAN AUDITION A FEW RADIOS.

Of course we need to do this side by side, in particular to do a few tests on our own "Mark 1" Ear to see what the differences are.  Then we can sit down and pull out a few radios and see which we each prefer and why.  And you can explain and show what parameters that pleasing sound represents.

Regarding a pleasing sound - THAT is largely unrelated to pure receiver performance and more personal hearing/taste.  I've used radios whose performance has been measured to be excellent by their contemporary standards - and I CAN'T STAND LISTENING TO THEM.  Every ham who has been around a while has had this experience.

To me, the listening experience is much more important and pure RX performance, because most radios have BAGs of that!  But easy listening...  many don't.

Currently I really like the Yaesu FTDX-3000, -1200, -991, etc.  And that is a PERSONAL taste.  It's not arguable.

So, why not come on out from under your rock and let's see what you really look like.  Maybe we'll even have a great time and tell tall tales of great radios of the past and those yet to come.

I challenge YOU to drop the mask, halt your conspiracy against... well... everything, and JOIN THE COMMUNITY.

Try it.  You might like it.

One thing not being mentioned here is the ability to tailor sound with the DSP to one's liking. At first, I was concerned about buying a IC-7300 because with everything set to default settings, I found it a bit bright and harsh sounding. After I learned to tailor the audio settings to my liking, I love this radio and will keep it. I almost bought a TS590SG, but the clean clear NR of the Icom finally sold me.

I believe most of today's rigs with the stellar Sherwood numbers can be tailored to an acceptable sound with a little experimentation.

Todd:

I agree with your assessment that DSP can really help audio quality.  A lot.  While I find the recent Yaesu's to have very good, mellow RX "sound", even with the DSP OFF, I'm not sure it is ever really OFF.

One of my old favorite radios, the Kenwood TS-440SAT (still have a complete station - can't let it go) is a joy to use and a Bear to listen to for long periods due to its very harsh audio.  So when I do use it now, I attach a West Mountain Radio clrDSP unit to it (the later version with volume, level AND tone controls) and it works wonders.  I can now listen and operate with the 440 for hours without ear fatigue.

I've found the clrDSP works wonders even attached to more recent radios WITH noise reduction built in.  I also use one with my Icom R75 receiver, and it makes a MAJOR difference.

I would put in a big vote for the Icom IC-7410, as K7JQ mentions the IC-7600 being an excellent purchase, they IC-7410 is basically a 7600 without the screen and a couple of small extras, the 7410 is a superb radio to use ergonomically with a control at hand for majority of regular user functions, an excellent receiver and superb filtering, very good NR and 100% duty cycle with its massive alloy heat sink chassis, add the 6 khz and 3 khz filters for e'bay price for the pair (around $100 US) and it will compare very favourably with most sub $3500 offerings.
A considerable number have been sold worldwide and have proved very reliable , the ALC overshoot problem (as with the TS 590SG) in early ones has been corrected with a firmware adjustment and can be retro fixed.
With an Icom warranty here in Australia of 5 years these are an excellent value purchase.
This is like the 7600 a full sized rig with a dedicated RF output control! and easily accessed sub menu's for lesser used functions. An easily viewed screen and an audio that is pleasent and non  grating.
It was selling out after the IC-7300 hit the market at as low as 1K-$1100.
There aren't too many coming up for sale used, as they are a keeper for the price and specs,
a quick look at the E'Ham reviews will tell you that virtually all users are extremely pleased with it giving a 4.9 rating!
I like the 7410 so much I bought a second - true diversity reception for a new price $1500 less than a new IC-7600.
my shack also contains an IC-7200, Kenwood TS-480 Sat Yaesu FT-1000D and Icom IC-765.
just my take!

Title: RE: Best used High Performance HF Transceiver
Post by: KX2T on March 01, 2018, 07:15:15 AM
I have seen allot of good used radio's around the $900 or under price range, the early TS590S for under $800, the Icom IC7410 under $800 and maybe if you look hard enough the TS590SG but if you find a used IC7300 for even around the $900 price range Buy IT, its reciever performance is a cut above those other radio's and bests the IC7600's RX section, yes it has no dual watch but even on modes like CW the filtering combined with a good stiff front end was never available till now for this kind of investment. BTW the transmitter is also excellent as well with a clean SSB signal, Icom not only got the RX section down but the TX section as well.
So to coin you phrase BEST my money is on the IC7300 used, after owning and using a few current very good radio's like the TS590,K3,FTDX3000 I now use and own a IC7300. I will add another radio more than likely another SDR like a Flex 6300 or maybe a 6400 but these sdr radio's are IMO performing way above any of the superhet designs.

W8JX- I been round & round with you on this IC-7300 receiver performance. The IC-7300 is a noisy receiver in S7 and higher band noise environments. Also useless during field day- overloads like crazy. Many at QRZ are selling or sold the IC-7300 due to the noise issue. The TS-590SG is far superior and everyone knows it at QRZ.

He claims to be an amp expert but the people in the know in the amplifier realm know that Teddy K2JMY is the MAN in which seldom posts but has help and fix more amplifiers than almost anybody else in the NE parts of the states. Carl is just an old man that is basically cranky and has nothing better to do then put down other hams and make himself look like King but here again that is in his own mind.
As far as radio's go Sherwoods list is a starting point but between reading up on ARRL reviews, go to the DJ0 site for more in depth reviews done by Rob himself then from comments of end users plus trying to actually visit other hams shacks were you can see in action is the best way to chose or just buy the three your interested in at one time and sell off the ones that don't please you as much.
As far as the 7300 goes the OVF light will light up if the input signal is on the overly strong side which may overload the adc chip set, most times just a slight adjustment of the RF gain control will tame that situation plus I never used the pre amp on that radio when I owned it, W?O pre amp the MDS is over -130dbm which is 5 to 10db stronger sensitivity than almost any other radio W/O pre amp engaged and with it in is up around -140dbm.

Thank you for setting the record straight. I do not post unless I know exactly what I an talking about and that is why Carl lost the last two arguments on my posts.

Using no pre amp stages in line with the 7300 plus learning to use the RF gain control plus anywhere from #4 to #5 on the NR control goes a long way to making the 7300 vert palatable RX plus setting the audio bass and treble on the receive side works as well. O noise bands such as 40, 75/80 and 160 at night these controls come in very hand but like everything else in life you gotta learn how to use them.
