First talk about the SRF-M75, this machine is beautiful boot after power frequency, need to manually change the frequency. Press the band key + scan button, 6 seconds, 6 seconds after the AM to 9KHZ, FM to 0.05 step. Suitable for use in Asia.

In addition to FM, AM reception, as well as heart rate testing, stopwatch function, fully explain this is to exercise the use of models. Printed in big red sports top. Heart rate is a simple test, press the Pulse button, finger on the next hole, the other a few seconds, the heart rate has been calculated and displayed on the LCD. Machine has its own built-in clock, and timer off function. M75PM has MEGA BASS function. Open MEGA BASS function, enhance the bass a lot, not like you can turn off the sound quality is relatively flat.

M75PM using monolithic receiver IC, CXA1238M, this chip is sony eat food alone, not to others to use, on their own use. Of course, performance is absolutely ok. In the noisy, high-speed bus, but also has excellent receiver performance, anti-electromagnetic interference performance. Serious interference in the electromagnetic leakage areas compared to similar machines have better reception. Selectivity is worse than the Degen 1103, 1103 can be well separated by the separation of the weak and strong station near 0.2Mhz Taiwan, M75PM not. (The DE1103 Degen is a rarity, FM performance laptop in invincible), of course, de1103 targeting a high-performance laptop, is not a volume player. Not comparable, but as a reference. Similar small machines than the domestic lot stronger. (NND, the high price of a lot of it, you pay for?)

SRF-M35, this little machine, looks very pleasant, four-corner. Like with the M75, turn need to manually change the frequency of power-down, press the band button + 4 button, 6 seconds after the AM to 9KHZ, FM to 0.05 step. For M35 not carefully studied the internal structure, was evidently Yuan Huhu, simply to win with a. A clock, kept 15 stations, there is no MEGA BASS function, test results, there is no M75 is good, as in the anti-jamming performance M75. FM used in the same environment, interference noise than M75 obvious. AM in the wave section, the performance with the M75, M75, but low-noise ratio significantly. M35 looks like personally, but unfortunately there is no MB, receiving almost interference, sensitivity several small machines are similar.

SRF-39 is an analog tuning machines, unlike the above two are digital PLL frequency synthesizer control. SRF-39 looks flat, but there are also detached weapon inside CXA1129N, is sony does not give it their exclusive home of the ic chips. The chip in the famous SRF-S83 is also used. Using a 5 cell, super-power design. AM / FM two band radio, a stereo, remote control of local sensitivity. Tested, SRF-39’s performance CXA1129N foundation, really good, FM performance is almost the same M75, turned out to be the best wave in AM section, low noise is very low, lower than the M75. Polish mellow sound quality, background noise can not be heard. SRF-39 FM performance, thanks to this little machine CXA1129, once the received signal, demodulating the stereo soon.

To three rows of two-bit machine:

AM, the noise floor more: 39> M75> M35, sensitivity about the same.

FM sensitivity: M75> 39 = M35, M35 bus to use in anti-interference worse than the M75, M35 than 39 strong.

Sound comparison: listen headphones MDR-E805, M75 has MEGA BASS, bass good elasticity. M35 flat, high-frequency clarity. 39 more calm, without any modification of the original sound, like.
