Results Summary:
Due to time constraints, only tested the FM section, and at noon it is not a good time is not short-wave test.
Let me DE1125. In strong signals DE1125 performance obviously clear 1125 sound frequency positioning is very accurate, even in strong signal, the frequency offset of 0.05 will be significant signal changes. But the poor performance of weak units, even move to the window and no response.
RP007 satisfactory performance, especially in the weak units, to close the window, the effect will be much improved, if the outdoor test if the estimated PK, 007 would be much more favorable.
RP2100 failed to show who should be the strong style, it can receive the basic units 007 can receive, for weak signal reception is sorry its long antenna. I also have a 1103, although not able to bring together the test unit, but I feel 1103 is better FM reception than the 2100. There is its frequency shift in the use of auto-tuning when the UP or DOWN is true (that time is a partial 0.1). Frequency sensitivity and bias, I estimate this machine’s personality differences, which I will consult Lele.
Special note: when you choose to use a test on a fixed frequency, the 2100 partial-band, reception obviously not good. This time, taking into account this factor, tuning auto tuning when not using, instead of using hand, the frequency of their best subject, so the overall performance better than last time. So this time the test is not in contradiction with the previous one.
I hope Shaoyou review.
