    Думаю получше моего ft1kmpv, но
    надежность не очень и как я понимаю сервисное обслуживание на территории СНГ тоже никакое.

    Цена так же немаленькая, но штатовская вполне подьемная хотя 4 штуки пока для меня это безумно за радио.
    С другой сторны, в Москве почти 6 килобаксов за аппарат с тюнером.

    Короче, если бы я жил в штатах, обязательно его бы попробовал. А пока из-за достаточно высокой цены, а еще больше от боязни влететь с гаратнийным ремонтом, пока воздерживаюсь. Хотя, мысль привезти его себе на попробовать возникает все чаще.

    Ten Tec Orion – 2 years on – Bob Henderson, 5B4AGN

    It’s now a full two years since I reviewed Ten Tec’s Orion for Focus. Time then, for a look at how Orion has developed and how my feelings for it have changed with experience.

    As we all know, manufacturers’ specifications can be seriously misleading. Usually this is not a consequence of what they tell us but rather, what they don’t. For my money, third order IMD dynamic range (IMD3DR) is the most telling specification, when considering how a receiver will perform in a strong signal environment. The key to evaluating manufacturer’s claims for IMD3DR performance is to pay attention to the frequency displacement of the two interfering signals used in making this measurement. An impressive IMD3DR at 50kHz spacing will provide only cold comfort during a contest, where within a 50kHz bandwidth there are likely to be over a hundred monstrously strong signals. What matters more, is how a receiver performs with close-in interference.

    At 102dB* I believe the Icom IC7800 has the best IMD3DR measured at 20kHz displacement of any commercially manufactured amateur transceiver. Orion, though still impressive at 20kHz, trails this by 6dB at 96dB*. What is much more important however is what happens when IMD3DR is measured at much narrower displacement. At 2kHz, Icom’s IC7800 deteriorates a full 22 dB to only 80dB*, whereas deterioration on Ten Tec’s Orion is just 3dB falling to 93dB*. So when it comes to avoiding having to listen to that indecipherable code near the noise floor, the audible consequence of inadequate IMD3DR performance, Orion leads the IC7800 by a full 13dB. Orion continues to hold the crown for the best overall signal handling performance of any commercially manufactured amateur bands transceiver.

    As I write this piece, I am unaware of any commercial transceiver closer on Orion’s heals in this regard than the IC7800. That such an expensive radio should fall so far behind Orion for close-in signal handling, is a direct consequence of the up-conversion architecture adopted by Japanese manufacturers. This approach has been avoided by Ten Tec with good reason and to good effect.

    My Orions have had almost daily use since I bought them. Neither has suffered any hardware failure during that time. Aside from the poor tactile feedback provided by the front panel momentary switches and the lack of colour in the 115 x 85mm display, I can find little to be critical about in day to day use. There is however a shortcoming in the deployment of narrow roofing filters, which does detract from the full hardware potential of Orion, in certain circumstances. This largely arises through Ten Tec’s decision to re-use the first IF filter set from the Omni range in Orion. This sadly was a mistake. Use of these filters in the optional 500Hz and 250Hz roofer slots causes significant deterioration in close in IMD3DR. Consequently, deployment of these filters in Orion is largely undesirable. This has been addressed in Orion 2, which has a completely new set of roofing filters, appropriately designed for the task. In the current form, these cannot be deployed in Orion but there has been suggestion an upgrade kit might be made available. Time will tell.

    Currently, the optimum roofing filter configuration for CW use in Orion, as opposed to Orion 2, requires purchase of an additional 600Hz roofer from Inrad. This must be installed in place of the stock 1kHz filter, which continues to be useful if transferred to the vacant 1.8kHz slot. Such is possible unless you already have an optional 1.8kHz filter installed in that location. Deployment of the 4-pole Inrad 600Hz roofer in Orion will yield substantially the same performance as should be available with Orion 2, with the exception that Orion 2 also offers an optional 300Hz filter. Use of the 300Hz filter in Orion 2 should provide further enhancement of very close-in IMD3DR, whilst at the same time sharpening narrow bandwidth skirts. So far however, I have seen no lab test reports which either confirm the realisation of this or otherwise.

    Ten Tec’s Orion 2 started shipping in December. There are three main differences between Orion and Orion 2 (ignoring price). The first is the introduction of a colour TFT display, which replaces the black & white unit used in Orion. This change is largely cosmetic but significantly improves the look and feel of Orion. Of course, it also adds clarity to the information readout provided. The second is the new roofing filter scheme, which hopefully will have avoided the IMD3DR deterioration seen when using narrow filters in Orion. The third is replacement of the main processor by the more powerful Motorola Freescale Dragonball Super VZ chip. This applies greater horsepower to the housekeeping tasks carried out within Orion 2 and should yield noticeable improvement in response speed to commands issued from front panel controls and those via RS-232.

    There is no doubt Ten Tec did a great job with Orion hardware and the three significant changes found in Orion 2 are welcome enhancements. All the more disappointing then, that Orion operating code has failed to match the very high standard set by the hardware.

    Early in 2005 Ten Tec embarked upon a complete rewrite of the Orion code. This was brought about due to problems in the architecture of the original code, which Ten Tec engineering felt limited the extent to which performance might be enhanced. These limitations affected both response speed and overall system stability. At that time the official release of operating software was V1.372.

    It is a rather sad and disappointing fact that after a full year of development, the released V2 operating code is inferior in several dimensions to V1.

    From my own perspective, my greatest disappointment is with QSK performance. V1.372 never made Orion a star performer as a QSK radio, though it was adequate for use up to around 35 wpm. Beyond that, T/R recovery was just too slow. Discussions with Ten Tec engineering, early last year, raised significant hope for improvement in QSK performance with V2 code. Sadly the opposite has been realised. The public release of V2 code for Orion has the usable QSK capability reduced to around 20 wpm.

    Just now Ten Tec is taking heat from users over a number of problems with the V2 operating code. Listing these in detail is beyond the scope of this article and is anyway something of a movable feast. Hopefully, the heat generated will provide the stimulus Ten Tec needs to correct the problems. I certainly would like to think so, though try as I may; I find it difficult to be optimistic. Having closely watched the development process over the last year as a beta tester, I have found it seriously wanting. Throughout development, bug fixes have been slow to come and their arrival has routinely heralded the accompaniment of several new bugs.

    All is not as it should be in the code development process. I am not a Ten Tec insider, so I can only guess at just what the problem is. However, having made my career in the computer industry and having invested Мulti-million pounds in software development projects during that time, I would say the signs suggest lack of a clear design specification and a similar lack of effective project management & review. As I said, I can only guess at the root cause of the malaise but its consequences are clear.

    Orion 2 is a beautiful looking radio based on a robust hardware design. Sadly this is not enough. I would love to invest in upgrading my Orions to Orion 2, to take advantage of the colour display, improved roofing filters and faster Dragonball control processor. Instead, I will keep my money in the bank, because due to the change in Dragonball processor, Orion 2 can’t run the V1 code and that’s the only code that makes Orion any use to me at all.

    I sincerely hope to be able to write another piece on Orion/Orion 2 in a year’s time, in which I can tell of the impressive progress made by Ten Tec in providing operating code that fulfils the potential of Orion. Today the school report style verdict would be:

    “Enormous potential – squandered.”

    Somewhere along the line, Ten Tec management appear to have taken their eyes off the ball. If Orion and Orion 2 are to achieve their potential, they will need to increase their focus and put some real muscle behind their code development process. Let’s hope they do.

    Вот поэтому именно в след раз куплю скорее всего Орион 2 а не ft2000, про3 или 7800

    Для меня новый руфинг это существенная разница, поэтому Орион 2. Единственный серьезный минус в аппарате это кастрированный второй приемник. Ну почему они не сделали их одинаковыми как в 7800 ????

    Никогда не сказал бы что Орион 2 смотрится хорошо. Дизайн у него на мой взгляд просто отстойный, как и у предков серии Омни.
    Но с этим думаю можно жить, потому что приемник у аппарата скорее всего замечательный.

    Приемник не настолько замечательный, чтобы каждый день, включая его, думать, емае, какой же замечательный у него приемник. Я вот так думаю, включая мой старый добрый 765...А вот после включения
    1000 Field'a так думать не хочется.
    Наблюдая каждый день ужасную морду Ориона, будет хотеться от него избавиться все больше и больше.
    Что сделаешь, военная фирма - она военная и есть. Дрейки тоже были ужасными. Если бы в прошлые времена нашему ДОСААФу дали бы кучу денег на такие разработки, они были бы еще ужаснее...
    Мои симпатии остались на стороне 7800.
    Так же, как хваленый полудуплекс Омни 5 или 6 в эфире звучит много хуже, чем от 940 или 950 кенвудов.

    Избавиться от Ориона это скорее всего будет очень нетривиальная задача. Дизайн отстойный. С другой стороны, при всем уважении к 765, он нервно курит в коридоре, как и филд без руфинг фильтра или любой другой более или менее нормальный аппарат с ап конвершном. Об'ясню свою точку зрения.
    Зимой пробовал на прием филд с руфингом и без руфинга в телеграфных тестах. Как результат, победил старый ft102 , он резал близкие станции значительно лучше, хотя в филде стоит полный комплект инрада на телеграф.
    В SSB все не так плохо, там разница с руфингом очень значительная.
    Собственно, вот и все предпочтения.
    До тех пор пока в 7800 не будет 300Гц фильтра на первую ПЧ, никаких серьезных бенефитов по сравнению с Орионом у него не будет, по крайней мере для меня.

    Местный владелец Ориона 2 от него совсем не в восторге, равно как и второй испытатель этого же трансивера. Я этот аппарат не слушал, поэтому не буду высказывать свое мнение.

    Игорь, а можно емайл или позывной владельца ? хотелось бы задать ему некоторые вопросы
