The T6EX doesn't have a 3 position switch channel, so I had to combine channel 5 and 6 to get four modes. I made it work with a pot that has double terminals for each knob position, so that way there is always 2 pins to connect cables to for a single position.
Think of this knob as a bridge between same terminals: A to A, B to B, etc, closing the circuit to ground.
Channel 6 is connected to a terminal A and a terminal B from the opposite side.
Channel 5 is connected to a terminal B and C.
This is how the pot look like:
I got this switch at the Home Hardware in College st and and Spadina Av, Toronto, Canada. Sorry I don't have to much information about it. It's just a position knob.
Later, in the radio, I set up 2 PMIX mixes. they appear as PMX 1 and 2. PMX 1 it's at +70%, MAS (for master) is channel 6, SLV is channel 5, SW is channel 5.
PMX 2 is set to -60%, MAS ch6, SLV ch5, SW to ch5.
The final look:
Let me know what is not clear and I will edit this blog!

Comment by Ritchie on August 23, 2011 at 5:19am Ok well I've been buggering around and still haven't got it right but I'm glad we are both on the same page now :D
Can you confirm what channel you are connecting from the receiver to the APM board?
With ch5 giving the different pulsewidths is it just that channel connected or both?
Comment by estebanflyer on August 23, 2011 at 7:27am ch5 is the only channel I connect to the APM.
I'm going to check the radio programming one more time, just to be sure I wrote it down correctly.
Comment by Ritchie on August 24, 2011 at 10:11am Ah I shall disconnect my ch6 then. Here is hoping :)
Comment by Ritchie on September 9, 2011 at 12:52pm Nope that didnt help at all. Im still getting two frequencys over the four selections.
Comment by estebanflyer on September 9, 2011 at 2:10pm I know it's annoying to open up the radio, but maybe if you do so and send me pictures of your switch and the cabling I can see something you are not seeing.

I just my switch from MAPLINS and have opened my TX but it looks nothing like the picture in page 1. I will add photos in the next post so that you can guide me as I have 3 wires from both chanels 5 and 6 and I dont want to make any mistakes.
ill be right back with the pics.
Comment by estebanflyer on September 11, 2011 at 12:30am no problem. my radio had 2 wires for each channel, but i'm sure there is a way to figure it out. your radio was a 7C, right?
Comment by Olugbenga Ogunbusola on September 11, 2011 at 9:52am I use a Futabe 6EX actually. I hope the photo are clear enough for you to see.
The pot or switch I got from maplin is also in shot.
Comment by Olugbenga Ogunbusola on September 11, 2011 at 9:53am I dropped my Tx a while ago and broke the switch head for Channel 6 so now I use a servo screw for that. ops.
Comment by estebanflyer on September 11, 2011 at 10:07pm This radio is different than mine... I'm sure you can still make it work, and even get more modes out of it, but you can't follow my blog.
By checking continuity on the switches with a tester you should be able to find which of the 3 cables is the ground, once you know that all you can do is solder the ground cables from channel 5 and 6 to the pot and then randomly try connecting the rest of the cables. Also you mix in the radio is going to be different.
Good luck!
