I am trying to both study how this module works and make a TX. Pretty much I have a RC car remote (FS-GT2B) and what I want to do is miniaturize the TX. I am a little new to radio theory but am very willing to learn!

LED1 and R3

I have a question about the PCB/schematics Midelic RX REV F.

You use a blue LED with a 1k resistor. Due to my knowledge a typical blue LED has a Forward Voltage of about 3 - 4 V. If you calculate a current of 10mA, the output voltage of the MEGA8 is much to low (should be U = I*R + U_LED = 10mA*1kOhm + 3V = 13V)

When using a red LED (1.6V / 10mA) the R1 should be about 150 - 200 Ohm.

Am I wrong with my calculation or is it impossible to use this LED / resistor combination?
