I am planning to use the RT4 -433 AM transmitter from RF solutions (standard one that used to be sold by Maplin). The data sheet covers several modules so I have highlighted in yellow the one I have.
The supply voltage is stated as 2 to 14 V. That´s fine but what I need to know is if the transmit power is the same over the whole supply voltage range (the data sheet seems to state the power only at 5V) . If it is the same then I can just use the main regulated Picaxe supply at 5V. If power increases with voltage then I may try using a 12V supply.
