Kchibo DSP D91L 

Kchibo DSP D39L-2

DSP D48L 2

First of all thank Kchibo, I an ordinary radio enthusiasts have the opportunity to experience different types of DSP radio, has received a golden D91L, D39L black and D48L, put them together to make a simple comparison, as a reference the Degen DE1121 radio.

1 overall comparison

1.1 Appearance
  From the outside, Kchibo the DSP produced three portable radios are all types of smaller sizes, suitable for carrying out listening to, the use of lithium battery technology, both to ensure the radio needs 3.7V voltage, but also to ensure the radio’s size and weight in the control range.

1.2 Button
From a positive perspective, D91L, D39L and D48L button has two parts, a part is used to control volume and tuning, the other part is responsible for functions such as automatic search radio stations. Because D91L could not listen to shortwave, therefore, less meter band select button. In the absence of digital buttons, the three radio when listening to FM radio is still very easy, by automatically searching storage station will be able to survive, need only listen to when to choose, and in this way when listening to shortwave more trouble, on the one hand by the button tuning, listen to the efficiency is relatively low, on the other hand can only store 30 as shortwave, auto-search more than 30 storage units will restart after the coverage limit of the original radio. In addition, D91L, and “storage +” and “store -” two button arrangement does not meet the conventional, easy to mistakenly press, D48L button is also relatively dense, for large hands comrades operation is error-prone.

1.3 Screen
All three machines have a larger frequency, with calendar, clock function, playback can also display the current signal strength, signal to noise ratio and other information. But D91L no backlight is not conducive to night operations, and D39L screen is bright green backlight, D48L screen is yellow-green backlight, and can automatically adjust the intensity of external illumination brightness of the backlight.

1.4 external ports
Compared to other radios, this radio several DSP interface is not rich, D91L and D39L of the headphone jack on the radio to the left, and D48L headphone jack on the radio right side. On the current situation, DSP radio headset to listen to is really a common problem, how to remove background noise, is an important figure in one of the radio to improve. D48L left adds an antenna interface, you can submit a random soft-antenna signal reception.
2.FM receiving

Although many of the radio at home, I usually listen to most or FM radio, FM Shanghai classification program broadcast on the station for music, there is classical music, pop music, nostalgic music, news, finance, sports other programs are also each have their own frequency, so listen to relatively high.
The D91L, D39L and D48L and DE1121 together, comparing the situation more to listen to FM
Test Location: Shanghai Xujiahui district 2 floor window of a old
The following numerical level of sound quality, 1 for the worst and 5 is the best

1

Thus, in the city to listen to the radio signal is strong, the effect of these machines are very good, but when the signal is weak, D91L listening ability will be immediately affected, and D39L and D48L performance of two machines more close to.
