How do I increase the range of my RF transmitter?
The experiment shows that the power transmission to the antennas can be increased by increasing the supply voltage.
The operational range of the RF module is directly proportional to power transmission.
It can be doubled by doubling the supply voltage..

How can I increase the range of my radio transmitter?
In most cases, you use transistors (and/or tubes) to amplify the RF signal from the transmitter. Sometimes, the least expensive way to increase range is to use a bigger antenna, a higher antenna, a more efficient antenna, or a directional antenna.

How do you increase radio frequency?
At AM reception, reception frequency is given by LC oscillating circuit (reception). For a smaller reception frequency, roll several extra turns on the coil. For a higher reception frequency, you can unroll turns from coil. There is also a frequency converter that is placed on the antenna.
How do you change the frequency of a RF module?
The receiver frequency is fairly easy to adjust, turning out the glued in inductor reduces the frequency, I was able to turn mine down to 405MHz by completely turning out the iron screw. You cannot easily change the carrier freq. as this simple design uses a Narrowband SAW filter.
