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

 

Simple antenna of TR10RDX that monkey understands

The flight of the electric wave worsens extremely because it doesn't tune the antenna of the attachment to TR10RDX to the frequency. The electric wave is prevented from flying.

It is somewhat improved if it is adjusted to length (1/4 ramda) in which the length of the antenna is tuned easily to the frequency. However, for attention because the electric wave doesn't fly straight because it doesn't become good at the mere consolation level alone only it is because it is able not to call this such an antenna, that is, a simple way of surpassing at one to the end o'clock alone and do not exist.
 

[1]
The antenna and the lead line (If it is an electric wire, anything is good) of TR10RDX are prepared by about 1m.
Clothes in the line are peeled off by about 5cm.

 
 
 

[2]
The line peeled off is previously wrapped about the antenna of TR10RDX.

 
 
 

[3]
It twists so as not to come off from the line that the antenna previously wrapped and it fixes.
It is better when fixing with solder etc.

 
 
 

[4]
The length of the line tuned to the frequency by/(frequency)300/4 x(shortening rate) (total length) is requested. It becomes the length of about 80.7cm as an example for 88. 2MHz because of feeling by 300/88.2/4 x 0.95=0.80782. The flight of the electric wave worsens because it doesn't tune it to the electric wave even if it is even longer than this length or shorter.
 

The lead line is cut so that length with the lead line including the antenna of TR10RDX may become 80.7cm.

 
[5]
The length tuned at 88.2MHz is 80.7cm.

 
 
 
 

The putting antenna taken in the main body of TR10RDX is separated from the obstacle and it sets it up vertically.
The electric wave doesn't fly to the installation method the tune's not entering over the point of the lead line by the string etc. with the pin if it doesn't use it while pulled. The electric wave doesn't fly because it doesn't obtain the tune frequency the same as the calculation when is so that the obstacle is near. Please devise it as the lead line is stuck on a stick plastic etc. (nonmetal) with the cellophane adhesive tape etc.

 

Is if the length of the lead line tunes it to the frequency well, the distance of a jump of the electric wave of TR10RDX five times compared with the antenna of the attachment?It increases by a factor of ten.
 
 
 
 
 
 

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

1. Power up TR-10RDX.
2. The distance of a jump of the electric wave of 10RDX. A super-simple antenna.
3. Let's draw out the output from 10RDX outside with the coaxial cable.
 
4. Let's emit a straight sound from TR-10RDX.
5. Does the version improve before one is aware, and did the sound change?
