arduino radio transmitter

Hi everyone

I intend to make a radio transmitter from Arduino that can transmit signals in the range of 100-150MHz.

Can someone please guide me about which module can I use?

Thanks in advance

In the Netherlands it is legal to use a FM transmitter from 87.5 to 108 MHz with a maximum power of 50 nW. There is no license needed to use such a device.
However, "fifty nano Watts" is close to nothing.

What do you mean by "transmit" ? Do you want to use an antenna and transmit the signal through the air ?

You’re going to be unpopular with users of airband radio.

I cant see how anyone can give any constructive help, you have not said what you want to use this transmitter for, so no-one can suggest a suitable transmitter type.

everything starts with Application. if not, then is the basis of an XY PROBLEM

what do you want to do ? send temperature readings from your weather station ?
send alarm signal from your mailbox ?

there are many radio frequency (RF) modules that can be used by an Arduino to send signals.
DISTANCE is the first question
OBSTACLES, or things in the way, trees, walls, etc.

Does this post relate to your other thread about a transmitter on a rotating platform?
As you have already discovered, there are NO legal Arduino modules that fit you requirement.
