WildCat FM /technical station.
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.

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.

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.
