The version improved before one is aware, and the sound changed...Nyaa!!

FM apprentice was surprised because 10RDX and the sound before were different when TR-1 0RDX that had been brought in was sounded and seen as WildCat FM...Nyaa!!
Is it three years of two years after TR-10RDX is put on the market?
The version will become Ver 1.9 what time it is.This version Ver 1.9 held out considerably and adjusted.

Judging from the emitted sound, the frequency response is taken, and, then the improvement. it makes it from the telephone before to the thing what kind of thing seen though it is a sound of TR-10RDX of Ver 1.9.

TR-10RDX Ver 1.9

This version Ver 1.9 held out considerably and adjusted...Nyan!!

The frequency response is understood compared with Ver 1.1 the version before the improvement The ape also understands the difference when comparing it to the frequency response measured before.

TR-10RDX Ver 1.1

The characteristic in which it dives for every 250Hz is from a thing to a considerable improvement of the frequency response in a low region in version Ver 1.9 to version Ver 1.1 when the frequency response in a low region is seen that has gone out up to about 60Hz.
However, the reproduction of the sound is still not "Dums" of Bass drum for a moment because it has fallen by 20Hz by about - as much as 5dB
Because the problem of PLL was closely related, the page of "Let's emit a straight sound from TR-10RDX" might have been difficult in the thing taken up around here.

The frequency response of the upper frequency is considerably improved, and 80Hz. It is a characteristic that manages to be flat up to 2000Hz.

the MPX signal extremely becomes intermodulation sound that exceeds it however by spurious of the MPX signal in "Yabai" when managing to become a flat characteristic up to about 12000Hz though the sound made "Shaki" is emitted...Nyaa!!

It seems that a very splendid frequency response as a toy of "398" transmitter.
 

The base is seen it is different whereabouts.

Marks are not and have vanished to the capacitor of the coupling capacitor of the capacity shortage input that became a problem on the page of "Let's emit a straight sound from TR-10RDX", C1, C3, and 0.1uF, too. The circuit of the input is improved,
and it understands a composition an uncouth circuit including the coupling capacitor etc taking simple
Version 1.1image compare clear....Nyaa!!
It is becoming by which there are a lot of parts and a good sound wants to see the proof not going out

in the basis of the circuit design, are the thing and the simplicity is best that puts out the maximum performance in minimum parts things.?
 
 
 
 
 
 

 
 
it is mini FM Toy transmitter /TR-10RDX - What do you want to do with a toy of this "398" FM transmitter ?
