DE1107 (7 fans) is DEGEN latest products, high-end enthusiasts series DEGEN radio series, emphasizing the receiver performance and fun to use. Starting from the first generation of DE1101, fans series has been broadcast enthusiasts recognition and support, especially DE1103 more innovative use interface and its leading receiver performance (high-frequency double-conversion, practical Shuttle tuning) to prove to the industry the DEGEN company’s technical strength and a strong challenge to the moral health of the radio dominance.

DE1107 Series is the only simulation enthusiasts pointer radio, apparently DEGEN the German students 9700DX models as direct competition, the German students after the company launched 9700DX pointer machine in the simulation market very long time rival, DE1107 in this market to there must be something worth the shortcomings of, let’s look at this new model for the radio enthusiasts what.

1 clock-controlled auto shutdown and sleep:
Radio-controlled clock is not a new thing, but in high-performance machine equipped with clock function pointer, but only DE1107 done. Sleep timer off function is very useful to use as a bed, no one wants to wake up after hearing the radio is still broadcasting. DE1107 sleep off the time is adjustable, but I find there is a small sleep shutdown bug, that is to set the time automatically shut down within 2 minutes after the re-start the sleep timer can not be shutdown, hope DEGEN can pay attention to this issue and follow-up production be improved.

2 practical options appropriate third gear Sensitivity:
Many radios have a sensitivity option, but did not carefully calculate the amount of attenuation, usually Local file receiver sensitivity is too low, there is little chance of being used, and DE1107 sensitivity attenuation has been selected carefully weighed, third gear apparent sensitivity of the differential but not the poor, high-sensitivity radio gear can play all of the DX performance, while the sensitivity of the receiving file does not significantly reduce performance, but at the end of noise has decreased, most suitable for normal listening, but the low sensitivity of the receiver sensitivity is still sufficient to file to deal with the usual international radio stations, and noise into a lower, mid-range and low sensitivity in the use of the time, we can clearly feel the quiet, leisurely old machine tuning transistor fun.

3. Shortwave band did not whistle the whole:
9700 series of radio frequency as the German secondary students, “Wang HF” series win in the market was a great success, but there are some more or less in the short whistle band, especially the 25 meter band is more obvious and the tuning listen to the fun, and the second conversion of the DEGEN 1107 launch is almost no problem, although you can still find the image frequency interference by the test point and the intermediate frequency interference points, but in reality both sides are very quiet and listen to the radio, did not find Desheng two -conversion machine-specific howling.

4. Pompon sound:
DE1107 sound quality is undoubtedly the most outstanding amateur series, the subjective sense of hearing than DE1103 and far more than SONY7600, not sure I made a compensation circuit, but in any case, 1107’s sound quality is sweet, you can meet the most people appreciate the approach, especially in low-frequency part of the more fluffy Grundig machine sound.

5. Reception
DEGEN DE1107 said the performance was not inferior to DE1103, it is confident performance. After comparing the actual audition, the sensitivity and selectivity is not subjective feel inferior DE1103 and SONY7600, but in any case low-IF double-conversion unit can not be compared to high-frequency double-conversion machine, at least in the band called the image frequency suppression and the handling of point high frequency machine on the dominant position. DE1107 receiver dynamic than DE1103, in the case of using long-term overload whistle, only to receive files with low sensitivity can be improved. All in all, DE1107 antenna using a random case, the actual results with commercially available high-end radio is no different.

6 technology and ergonomics:
DE1107 manufacturing process combined with the quality of the basic medium, but the process compared with the German students have gaps, for example, DE1107 dial the backlight is not bright band indicates that no lighting, body a bit staggering. Backlight illumination is independent of control, turn off the radio after the power light is still working. DE1107 rotary band switch is a bright spot, an advantage of using the rotary switch can be switched quickly and accurately positioning band, while the linear band switch is usually easy to push too far. May be considered a cost, DE1107 button design is not ideal, it is important to switch the power switch and the backlight is a mold, and important sleep time off the clock set button and the button is a mold, LED light scattering are not doing enough , felt a bit harsh.

7 accessories and other
DE1107 Built-in charging circuit and a separate charge switch, and configure the external power supply (with charging function), but did not come with rechargeable batteries, the headphones sound very random, but phase errors, may be an isolated phenomenon. Comes with a nice collection bag.

8 Summary:
DE1107 is a beautiful sound, the second receiving performance radio frequency, on behalf of the domestic secondary pointer of the radio frequency the highest level, it is worth playing and listening.
