With this machine to listen to DAB + and FM listening first distinct feeling that the separation of the left and right stereo DAB + sound much stronger degree than

FM, even though I had a sixties man, a boot Now hear this difference is, three-dimensional feel very strongly ;

Best FM audio indicator is composed of 30 Hz -15 KHz SNR 70db, while the DAB + audio effects can be done best by 5 Hz – 20 KHz….;

.. This machine, for example, FM tuner audio range of 30 Hz – 12 KHz SNR 65db, stereo separation is 1 KHz 35 db;.. While the DAB tuner audio range just by the 5 Hz –

20 KHz noise ratio 105db, stereo separation is 1 KHz 100 db.;

Shenzhen East when using this machine, you want to accept the use of a dedicated VHF 220 MHz Yagi antenna, mounted on the balcony, refers to the southeast.;

At this point the DAB + reception signal strength is about 116, over the threshold of 80 that is stable reception.

4A unit FM antenna and Yagi antenna three units or five units of different multi-unit Yagi antenna directivity strong for acceptance specified direction source of the signal, while unit FM antenna, you can receive signals from all directions; another Yagi the more antenna elements, the greater the volume, convenient easy installation on the balcony;

This machine has left three red indicator lights, left one is the power light, left the tuning indicator lights when there is sufficient signal and accurate tuning, second from left lights up.

Medium wave broadcast reception

High wave sensitivity, I used the radio head , medium wave radio receiver sensitivity highest one ;
Since listening position close to the south waterfront , when equipped with a random box -shaped antenna , antenna attached after this test, the signal is good at the windows ;
Pictures can see no skyscrapers blocking out the window and could see a lot of sky position , the electromagnetic environment is still relatively good , with this machine AM sensitivity is also high, so that even in the daytime , you can also receive Philippine radio 4 and the south east of Taiwan, a radio station ;

Receive would be so multi- wave radio, this can be used as medium wave radio head DX uses random medium wave antenna should also be a credit that many heads supplied with the radio wave frame antenna , the wiring is not used stranded wire is used for equilibration , which machine is connected to the line of the frame antenna , or just using 50 ohm coaxial cable 75 ;

Use coaxial cable has the advantage that it has a noise shield , protecting the role of the signal , so you can pull the frame antenna farther , placed in the best position signal ; while stranded wire or balanced line using a frame-shaped wave antennas, such as the lead was stretched too thin , it will infect the indoor power noise and noise pollution could have a very clean signal .

It is worth mentioning that evening to receive the AM radio more , especially the Philippines this radio signal is very strong and stable , you can receive at 19 o’clock after midnight when the signal is stronger :
SIN radio frequency
554 558 KHz. Philippine DXXL Radio ( Philippines , United Kingdom )

This radio at 2:00 to 4:00 are inserted continuously broadcast the human voice is not very pleasant songs and songs in English , although Hong Kong has a lot of oldies radio stations have broadcast in English , but may be due to old records inventory and chair different tastes , which will be broadcast on several radio stations in Hong Kong often been difficult to hear the old songs peacetime , memorable , to accompany me to sleep many nights companion .

Receiving radio network i-RADIO
As network radio reception function of this machine , and other network radio not much difference , registration and login Frontier Silicon Radio Portal this internet radio site , can receive more than ten thousand Internet radio stations worldwide .

Attachment of the machine has a remote control, AM frame antenna , DAB + indoor antenna , WLAN WI-FI antenna …. and so on.

Weakness / room for improvement at :

When listening to DAB +, did not loom as DGTEC DG-DAB888R this unique DAB color display , machine shown below: FM selectivity , and less than the figure under the machine SONY 333ESXII, met two strong stations in the adjacent 0.1 MHz when , weak and strong stations will be some crosstalk , and SONY 333ESXII not ;

When you go to listen to Internet radio from AM / FM, takes longer ; converted from Internet radio AM / FM versa !
DAB + signals from the 0-255 series , there are threshold when listening to the signal strength at 80 or above , it is possible to stably receive broadcasts ;
Receive Hong Kong DAB in Huiyang District, Shenzhen East + already belongs to the edge zone , early in Hong Kong DAB + pilot , the signal is relatively stable and easy to close later in the year , the Hong Kong side may adjust the signal strength to the north fired , no previous good income, in when the day receiving , but sometimes signal threshold ;

At the edge of the reception area , DAB + signals relatively weaker in the spring and summer , fall and winter seasons are more strong in some , and 21:00 the following morning signals to signal other time off than some strong ;

Summary: This machine can be said to be a model of modern radio head , to have sound quality , can be DX DX AM or FM DX, to receive foreign radio remote can listen to Internet radio this machine . Although this machine is not equipped shortwave , but then still meet the requirements of modern broadcasting lovers ! Listen to foreign radio stations ? Through the Internet will be able to connect more than ten thousand Internet radio stations around the world , and is far and referral, as long as you the network will be able to force ( of course, the human factor must be excluded GFW ) ! can say that this machine the near, medium and long-range radio are caught up .
