What a great radio  Time owned: more than 12 months
Probably my favorite radio over the years.
Does a great job on all modes, excellent on CW and AM....
Sounds best with a larger speaker, can't say enough about it.
Will get another one some day, now using another radio on remote base for CW.

From Now On... Ten Tec!  Time owned: 3 to 6 months
Love this radio. It's a late model Jupiter 538 AT with the 1.33 firmware purchased used direct from Ten Tec.

I bought it to replace my venerable old Kenwood TS-450AT. Great radio for it's time and as an introduction to HF, but it was time to move into the 21st century.

There's enough room inside for another radio which suits me just fine. The large face provides plenty of room for large buttons, switches and knobs with large, readable print and due to a unique and user friendly menu selection system, not too many of them. Perfect for my fat fingers and trifocaled eyeballs.

This radio is very quiet with no lack of sensitivity and TX/RX audio is excellent. The Jupiter was on the cutting edge of DSP during it's earlier days and it's still very effective, especially with the most up to date firmware.

Ten Tec sold me a used radio that was indistinguishable from new with a warranty and all accessories included as new for $1200.00. Not too bad considering this radio was selling new for $1900.00 less than a year before this writing.

A very few people gave the Jupiter poor reviews here. IMO, they never gave it a chance. Their loss.

Best Buy  Time owned: more than 12 months
First I am a great TENTEC fan and user for last 20 years. There service to me is second to none. Always friendly and helpful and I ask some dumb question. Moved from a Paragon to a Jupiter and it was a very good choice. You move into the digital world with it. Easy to read dials and VERY simple to use. Took a few days of checking my signals and reports to adjust the menu settings to my voice and operating procedures. 51 countries in 23 days in Missouri, worked Africa, Russia, Japan, Australia and several DX expeditions all on a ZERO FIVE vertical, how could it be better. Excellent receive - heard India, Iran and other asian countries. If you can hear them you can work them and you can hear (Luck also helps in pileups). Can isolate signals till there are perfect and excellent listening. Miss the touch pad for band changes but i've got use to it and understand why feature was dropped. Very light unit and displays well in my shack. Very quiet radio and for the price of a used unit it is the best value buy out there. If you ever use a TENTEC product you will be a loyal owner. If I ever buy another radio the JUPITER will stay in my shack. Been operator for 25 years and this is a joy to operate. Highly recommend this radio even for the most skilled operator. It is capable of more than I'll ever be able to do. Does digital, cw decoding, remote control operations and cw from keyboard. Something for everyone. I bought my unit second hand from TENTEC direct, was reconditioned, checked out, loaded with latest firmware and looked like it never was used. The sale people well represented it along with return privileges and 30 day warranty. It seems to me that they will support this unit for sometime and that they regularly have used unit on there site. AMERICAN MADE, sold and serviced here in the USA. Check out your rig and see if you can say this. I have never called sales or technical department and got a recording, ALWAYS answered quickly by a real person. New TENTECs are only sold through their factory and I thinks thats good price wise and service wise. Taught for 32 years so I've dealt with a lot of people and companies and these people are very very good. A quality product from a quality company at a reasonable price. Plus you always deal with an experienced ham operator. TENTEC on their sites also has excellent videos on many item and product usage. 73s

Outstanding  Time owned: more than 12 months
The Jupiter is the perfect radio for me, very easy to operate, and a simple menu system. I am always getting complimented on my crystal clear audio. Ten tec customer service cannot be beat, they always strive to satisfy. I would like to see if you could get that kind of service with the products from Japan, I think not!. Great job Ten tec

Excelent 558AT  Time owned: 0 to 3 months
The radio TEN-TEC JUPITER 538AT is one of the radios quietest I've ever seen.
There is one traditional wheezing in our heads, so do not get tired listening.
  It comes from the factory locked but it is very easy to unlock it via software, simply connect the software pegasus it opens any banda.

It has many features that you receive equalizes the voice of the person the way you want.
NR filter for noisy places really works and resolves without distorting the modulation.
I like the radio 'cause the buttons are all looking kind of like the old days people used, hence it is very easy to operate it at all.
It has an excellent internal coupler, a cw decoder and you can connect a keyboard and do cw keyboard .. very good.
Not to mention the beauty of radio ..
It's really different from most Japanese brands besides being a legitimate SDR.

O radio TEN-TEC JUPITER 538AT é um dos rádios mais silenciosos que já vi.Não fica aquela chieira tradicional na nossa cabeça, portanto não cansa a escuta.Ele vem bloqueado de fabrica mas é muito fácil desbloquea-lo via software, bastando ligar o software pegasus ele abre qualquer banda.Possui muitos recursos de recepção que você equaliza a voz da pessoa do jeito que você quiser.o filtro NR para locais barulhentos realmente funciona e resolve, sem distorcer a modulação.Eu gosto desse radio pq os botoes são todos a vista tipo como a gente usava antigamente,dai é muito fácil opera-lo em tudo.Possui um excelente acoplador interno, um decodificador de cw e você pode ligar um teclado e fazer cw via teclado..muito bom.Sem contar a beleza do radio..É realmente diferente da maioria das marcas japonêsas m de ser um legítimo SDR.

Holds Its Own  Time owned: more than 12 months
The Jupiter is one of, if not the, oldest of transceivers in the lower-priced ham market, yet it more than holds its own, IMHO. It's virtues are many, its faults few and, from my point of view, not significant. On the other hand, the Jupiter's chief competitor (IMHO), the new Icom IC-7410, is also a fine rig but it has two glaring faults, enumerated in many of the eHam reviews, which could be deal killers for some.

For me, the chief virtues of the Jupiter are: (1) its near perfect ergonomics; (2) its upgraded case and controls; (3) its bright blue screen with highly readable lettering; (4) its (optional) remote pad that allows armchair tuning, etc.; (5) its CW capabilities (send/receive and useable without a computer) with just a keyboard; (6) very good send/receive audio; (7) a robust (optional) antenna tuner; and (8) great QSK.

The nits? Well I really miss a carrying handle, which all of the other competitive rigs offer. Also, as has been mentioned previously, the NR function is mostly useless, and I cannot discern whether the AN (auto-notch) function works at all. These probably unfixable faults revert back to the ancient firmware/software that originated in the Pegasus, which served as the progenitor of the Jupiter.

All in all, a surprisingly fine, robust rig that holds its own against the competition. If bought new, it is a bit pricey. To me, the added cost is worth it for the remote pad's convenience and the CW send/receive functions. YMMV (This is my second, or perhaps third, Jupiter, so although I've just purchased a new Jupiter, my experience with them goes way back. The new one is going to be in the shack for many years, not as my main rig necessarily, but at a minimum as a very useful second one.)

1.5 year review  Time owned: more than 12 months
Having owned the Jupiter for 1.5 years now, I feel I'm in a good position to write a good review, which is really just my opinion.
This is my second review of the Jupiter.

The receiver is very good and I like the 39 IF-DSP selectable filters. They work very well when narrowing in on a hard-to-copy CW contact or when working SSB.

I don't like the spectrum sweep, but on this kind of LCD screen it is adequate.

I've used my laptop and interface to control the Jupiter in Pegasus emulation mode a few times but is not my normal radio control method. I bought the interface cable to try the Pegasus mode because I was curious. The graphics remind me of a late 80's video game.

The CW decoder is pretty tough to make work. It won't do well unless the signal is a couple of S-units above the noise, and you have to zero-beat the incoming station exactly. Even though you hear the tones better a bit off the frequency, the CW decoder doesn't get happy unless you're right on the other guy. I remedy this by using a Signalink interface to my PC running CW-Get software. You can use the IF-DSP filters in conjunction with the CW-Get software and really pull weak CW signals out. But the CW decoder wasn't really a selling point for me.

I found that when operating a high duty cycle mode like PSK-31, you will absolutely need a fan blowing on the heat sink, it gets hot. However, if you have a computer fan blowing on the heat sink, you can go 100 Watts with no temperature problems. I don't run PSK on my rig without the fan.

When the ten-tec ads tell you that your transmit audio is good, they are correct. Although I adjust my TX Filter Bandwidth down a bit, I have had a ham in Virginia record my audio and email it to me. It sounded ok to me.

The QSK is as smooth as they say.

I've read some review comments that say you have to cycle through all the bands to get to the band above the one you're on. That is incorrect information. Press ALT then BAND to go up a band. That can be repeated to go up bands instead of down.

READ YOUR MANUAL! I can't stress this enough. Get the most from your rig. This is true with any brand of radio.

The Noise Reduction works very well.

You can turn on/off a Monitor, I like it but it won't let you 'hear' any speech processing that is being done. You can adjust the speech processor too by the way.

I bought my Jupiter and the antenna tuner kit. I had to send the rig to Ten-Tec when I had a problem; and they said the tuner connections needed adjustment. I sent it in, it was still under the year's warranty and they had it back to me in a week's time.

The only negative thing I can say is that the knobs are kind of cheesy and have a cheap look and feel. But, the performance is rock solid.

I've made a lot of contacts in South America, Europe, the Carribbean and most of the United States and Canada on SSB, PSK, and CW, using commercial antennas and homebrew antennas.

I think the Jupiter is a good, rugged HF rig for Field Day. For the money spent I'm satisfied with it.

Everyone remarks about the Ten-Tec service being so good. It is GREAT! I have nothing against Kenwood, Icom or Yaesu, but I think if you had a problem with your rig, you'd not get the same quality of service you get with Ten-Tec.

I live in Tennessee, and supporting "Made in the USA" products is a big deal for me. I know it's not always the easiest thing to do, but when I drove to Sevierville and came home with the Jupiter, I felt better knowing I'm supporting an American business, especially one in my own state.

Keep going back to it.   Time owned: 6 to 12 months
I've owned many TenTec rigs over the years. They all had weak and strong points no matter the model
and price. I own a Jupiter and a IC-7410. So I have been comparing them for a while now. The 7410 has many features and many are very useful. But naturally it has the menus to go with it. I enjoy the 7410 to be sure. But I won't sell my Jupiter . The jupiter is so easy to learn and use. The constantly variable i.f. filter works very well. I get no ringing even when narrowed to 150hz. The menu system is the easiest to work with I have ever used. The knobs on mine do not feel wobbly or cheap. Being able to use any filter bandwidth with any mode is really handy. You can knock out unwanted signals on cw and psk31 so easily. I tried several speakers with the Jupiter and, to my ears, the Palstar SP-30H really lets this rigs audio section sing. All modes sound great to me. I purchased my Jupiter 2nd hand for less than 1/2 it's new price. So I did get a lot of radio for the money. Brand new, the 7410 sells for close to what a new Jupiter would cost. So, for the price, I'm not sure I would purchase the Jupiter over the 7410. The NR and NB on the 7410 is better implemented than the Jupiter's. Having the DSP NR variable rather than fixed like the Jupiter, makes on heck of a difference. Even weak signals are not lost if careful use of the NR control is used. The Jupiter's NR knocks all but the strongest signals out and unreadable. So it really isn't much help at my location at least. Cw is a joy with the Jupiter from the get go. The 7410 is not equal to it using full QSK. But--that said-- I think most operators would not really notice. And of course, the 7410 has 6 mtrs. Personally, I think the newer Jupiter with the black case, upgraded knobs and blue screen presents a real bargain on the used market. It's fun and simple to use but not so simple a rig that it is a non-performer. Remember, this is just the opinion of a non-contesting average operator. So take it as that. I like both rigs very much. Each has it's own character just like cars or motorcycles .

I'm keeping it  Time owned: 0 to 3 months
I just passed the trial period on this radio (they let you return it risk free within a month of purchase) and I have decided to keep it. I also own Elecraft K2's, Icom 718 and 706 (both MARS and marine modified). I don't contest, but enjoy SSB, CW as well as QRP.

Good things about this radio:
-It is very quiet and the filters and bandwidth filters work in a complete and uncomplicated way. Previous reviewers have commented on what a pleasure it is to listen to, and they are right
-Good sensitivity. There is no 'pre-amp' but it hears everything my K2 does
-Easily updated. It really is a SDR with knobs
-American made and American support is definitely a plus
-Just enough knobs and controls
-Fairly small footprint for radios of this quality. Could it be smaller? Perhaps, but I'm not complaining
-Price point is excellent. I bought a demo and got another $200 off
-Band scope is adequate and helps you survey the band. Don't expect an oscilloscope, but it works as advertised
-Signal reports have been good
-Tuner works as well as other radios

-Nothing really---if there were anything significant I would have returned the radio

Summary: This radio has made it a pleasure to listen to SSB again.

Best bang for the buck  Time owned: more than 12 months
This is my, Well I quit counting, Jupiter. I always seem to come back. Love the mellow sound of the rec. and lack of back ground noise. The large read out and simple menu make it a wonderful radio for the non con tester . Ten tec always there and ready to assist in any questions, and still repair their older radios. Try that with the JA RADIOS.I've had most of the others. Good job Ten Tec.
