With the RF switch, you can choose between two transmitter modules, such as 35MHz, Graupner HoTT 2.4,
or Weatronic Graupner|IFS. So you can also integrate another RF module in the transmitter and if necessa-
ry, just switch between the modules.
Both the operating voltage and the PPM signal is switched with the safety switch so that only one module is
activated and consumes electricity. The active module is indicated by a green or red LED.
The following combinations are possible:
HoTT - Weatronic
HoTT - iFS
HoTT - 35 MHz
iFS - Weatronic
iFS - 35 MHz
Weatronic - 35 MHz
