1, circuit frame very good, very powerful. 55.845M, German high school students laptops frequency double-conversion came.
Do not say H2k, Desheng before offered several double-conversion simulator, digging for the development of German students got pot of gold, from the current point of view, the simulator has the disadvantage of those, such as whistle, noise large etc. .. but after all was still walking in front of the domestic industry, while the German students on the application of new technologies PLL machine is hesitant, has not been using high-frequency double-conversion design, Desheng said that as long as a conversion machine to do good, still a good performance. But regardless of these competitors may, 1103 for the first time a high-frequency double-conversion, from a technical framework to German students left behind, Robinson then introduced high-frequency double-conversion machine, Kairon is followed, which for domestic Radio German students, who made the boss, has just launched high-frequency double-conversion machine, I was a little embarrassing, but fortunately came.
2, automatically search for fast, very practical
Civil PLL machine automatically search to find sets always Manmantuntun, people lose patience, and PL600 search speed has increased more than 3 times, so that automatically search is no longer a decoration.
3, shuttle very good, very smooth
PL550 I have not used the shuttle, a sense of people feeling very uncomfortable step and feel rough, slow sync lock, and DE1103 is a shuttle to conquer the world thanks to the fluidity, PL600 feel the shuttle closer to the DE1103 , very good, very smooth.
4, features a very full, very close
PLL600 meter band the first time show an increase in the continuous frequency search time, know when to have entered the meter band, and when to leave the meter band. Strange symbol and finally replaced by a solid three-stage battery display. Frequency of elections and the 7600 can finally do not need to press the enter key, like, very humane. Another six units selected mode, broadband narrowband conversion, ATS, pitch selection, charging, dual o’clock in the control, speed search everything. German students in the PL600 on the move a lot of thought, the thought can be said to have thought, had I said that PL350 is a very high degree of completion of the model, and PL600 off than the man-machine interface to a new height.
5, SSB
Although I almost did not listen to SSB, but there is a beat frequency knob always always remind the users this is a high-end machine, this function and high-frequency double-conversion, is universal machine, and do different watershed.
6, 1103 to receive and talk about the contrast sensitivity
PLL600 FM, sensitivity and selectivity and almost the same as 1103, Poland received if the 1103 count of 100, then the PL600 in about 90 minutes, short count 100, then 1103, PL600 in 95 minutes, that is, if not very, very carefully to compare very, very critical of the station, the two are not any major performance difference.
7, the problem points
Found only one that is installed on the PCB Shuttle height and shell do not fit in the shuttle of the shaft and shell holes of different axes, some stuck in use when feeling uncomfortable. (Add, just looked under the shaft and the chassis is not a problem which is already very smooth Shuttle, students can use on the alps of Germany like …)
8 questions
Need to set the battery charging capacity, do not charge a regular charge? When the battery is not used to charging will not overcharge? The instruction says is intelligent, how a smart method, curious.
PL600 Yes, I do back gunmen willing to buy a majority of people should not with regret, the premise, not to big shopping malls to buy, the price is too dark ..
9, supplement 1
Read the instructions before going to sleep under, found a little surprise: preset radio / saved browser can ignore the weak radio signal automatically sets to enhance the efficiency and speed of the preview. And machines, like cars, press the arrow keys, the radio can be saved in each user automatically for 5 seconds to decide whether to listen to the radio. For example, in a good environment, I am a 50 station presets, but poor signal environment to another, or some off the air at radio frequency, PL600, when the automatic preview scan will ignore weak signals saved radio, listening only to stay with the value of saved stations, very human. Of course, this feature can be turned off, everything left to the user’s own choice.
10, Supplement 2
Up in the morning and spent the next shuttle, Akira will be issued to promote the knob, as the shuttle as solid .. 1103
