From David, X9303 Multplex connector adding auto power on and ppm out:

(See post 3259 for more)
the two red wires go straight tru, and there is offcourse a hole in them and connected to the fet,
the fet is a low ohm value P-MOS FET, logic level gate drive type,
any type will do. then a 10K resistor over gate-source to keep it off,
and a diode to pull down the ON system to the radio, orange wire
back side of a 5 pin DIN:
RED 1 charge input.
YELL 4 ppm out to LRS.
RED 2 power out to LRS.
ORANGE 5 connect to 3 to turn on.
BLUE 3 GROUND to LRS and to charge cable
the 3-5 connection is made in the male din connector wired to the LRS, so when plugged all go on,
and unit go into student mode due to the diode, the other pictures show the other ends of wires.

From Blake, X9303 Multplex connector adding auto power on and ppm out:

Exactly same system and same mod as the one david have, but this time TWO fets are used in parallel,
since the new version of LRS TX can output raw 2W, more input supply power is offcourse also needed.


When running in "normal" mode, the 3.3V regulator gets quite hot this is fixed with this switcher, almost loss less.
