TECSUN

The PL-660 is the latest model in the the Tecsun high-performance portable band number of conditioners series flagship model is now the Tecsun portable radio.

This post can not be used as the evaluation, only an experience, so I can begin the views express in the former, the PL660 is an extraordinary portable full-band radio, I am this happy and portable old three (SONY 7600, Sangean 909 and YB400) par. Forum blue sky view is that this machine will become a milestone in the portable model, because it can meet the requirements of almost all of the radio, I agree with this view.

Following the Grundig, sony, Panasonic and other manufacturers to exit the radio market, Tecsun already become the leader of the international radio manufacturing. 10 years of development, Tecsun gradually form their own design style, good brand recognition, you get a Tecsun radio, immediately can feel the characteristics of the Tecsun machine exterior design, Tecsun machine use.

Makes the performance improvement with the gradual improvement of product ideas, improve the function of progressive new models shorter development cycle, reduce development costs, and easy access to reliable improvements, but the lack of character jump. The Tecsun the same series of multiple products, have similar style, simply, is the quantitative non-qualitative. PL660, quantitative on the basis of qualitative models.

Let’s look at the landmark models in the calendar year Tecsun:

– In 1997, the R9700 two variable frequency hand-tune machine, it seems from today’s perspective, the initial product of this venture is not worth mentioning, but at the time, but it is welcome international brands of similar products performance test of the model. Tecsun, time is so high profile, fearless, of course, the 9700 performance is actually not international brands of similar products for comparison, but by virtue of the 9 700, Tecsun to squeeze into the ranks of domestic first-line radio factory.

– 1998, PL757A, after following PL737 Tecsun perfect number-tune the performance of the PLL machine the launch PL757A, Tecsun towards the first building block of high-performance number-conditioners.

– 2000, HAM2000, that is, Grundig, ODM SAT800 This is a controversial desktop high-performance receiver, compared to the Grundig satellite series machine, the TecsunSAT800 the quality control and performance, there are gaps, but in any case, the SAT800 the developed into a

Power is the Tecsun one of the most important milestone, although the market sales is not great, but prove to the world their strength. Even from today’s perspective, HAM2000 or Tecsun ever produced and is producing models in the top the Tecsun follow-up the development S2000 is available as a simplified version of HAM2000, but performance still can not be compared with the HAM2000.

– In 2002, 9700DX, as was introduced R9700 Tecsun 9700DX’s launch is based on high expectations, we all remember Tecsun five-year sword “slogan, start from the 9700DX, the Tecsun in high-end laptop form factor design ideas preserved, and has been changed to PL660. R9700DX has a very low noise, high sensitivity and selectivity, from the 9700DX, Tecsun begun to focus on sound quality, another the 9700DX hand tune feel has significantly improved. But the 9700DX anti-strong-signal capability and tuning the whistle, people regret.

Tecsun began to enter the phase of rapid development, the PL series of portable computer has been rapidly expanding, PL200, PL350, PL450, PL 550, PL600 and so a series of dazzling models launched since last year, launched a series of DSP technology PLL machine type, the Tecsun number of tone models, features and performance continue to increase, until the PL 660.

The definition of PL660 milestone model, you need to have some justification:

– Inherited part of the essence of the past few years the Tecsun number conditioners Ergonomics is the PL660 the Tecsun machine soul, and ergonomic interface attaches great importance to the user experience, Tecsun perfect development for many years. Mentioned Tecsun and Degen, everyone has the same view, and DS Jin technology win win Tecsun a balanced is very good manipulation.

– A breakthrough performance. PL660Tecsun portable machine is the first model with synchronous detection, synchronous detection is a very complex technology, limited edition models of the domestic over the same period only DS Jin 1106. With synchronous detection, from Tecsun do not have to humble sony 7600GR. The results of the actual trial, the Tecsun the synchronous detection is very stable, easy operation and effective.

– External With the new breakthrough, PL660 get our hands on, I suddenly felt very similar to another the Tecsun the OEM models E10 and my collection, just like the picture above, the PL660 follow the design of E10, E10 I a few years before the Trustee brought back from the United States, I think that compared to fatigued box type the Tecsun conventional style, the PL660 arc panel design and narrow key design better visual effect, the PL660 is a very nice radio.

– Of PCBA technology, new breakthroughs, online three diagram, internal diagram a lot, improve the Tecsun internal work is actually visible, although there are still gaps and Japanese aircraft, but has been accepted.

– The rest, Tecsun for many functions of the trade-offs, in fact, the choice is also an art, and my experience is that first of all to easy to use, radio, and do not need to read the instructions can be very skilled to use, In addition, some advanced features in the manual quickly learn and master under the guidance of, basically, PL660 to do a similar kind of digital direct elections have been modified, first press the “Enter” key foolish practice is not common system code function rounding, an increase of the band of the short Bomi the ATS auto-tuning, an increase of the long-wave and aviation bands and SSB single sideband. The PL660 keys crowded, limited key combination to a reasonable number of features that make it function to understand and master no longer be a burden.

– Is particularly worth mentioning is the Tecsun finally abandoned stepper touch shuttle using the shuttle without stepping touch, and the PLL locking speed than previous models have greatly improved, we still remember the DS Jin DE1103 smooth Jog manipulation, the the PL660 already meet and exceed. Whether slow or fast step, continuous tuning Shuttle sonic boom, very smooth, similar to hand-tune machine feel.

– Ultra-low noise floor.

Received first edition last week, after the initial use of intelligent stepping experience is not satisfactory, look at the forum, many users have similar views, the Tecsun followed by rapid adjustments were made, on hand to improve the version. An increase of fast-stepping choice, so far, this machine for me is basically perfect.

Night using headphones, a speaker can not be perceived problem, the synchronous detector is turned on, the headphones wide bandwidth, very low frequency beat sound you can hear the sound of the end, I do not know not synchronize the injected carrier and radio carrier appeared a few 11 HZ frequency difference between the reason?
