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!

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?
Guys
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.
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.
Nope that didnt help at all. Im still getting two frequencys over the four selections.
Ah I shall disconnect my ch6 then. Here is hoping :)
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.
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?
The intention was to have ch5 giving 4 different pulsewidths, but as a result of the connections, you get ch6 also changing pulsewidth. I use ch5 to change modes. If you don't connect ch6, ch5 would only give ON and OFF pulsewidths, like in positions B and C (ON) and D (OFF).
Position A: ch6
Position B: ch6 and 5
Position C: ch5
Position D: none
In conclusion: I guess it's wrong to say that the ch5 is the master of this whole mix, it's shared by both channels.
I hope you can make it work.
No. I believed this was a way to mix ch5 and ch6 so only one channel would output. The output would be of tangible relation to the pulsewidths needed for mode selection. The setup you have listed when using the radio test outputs both channels as normal but with slightly shift end points.
Did you intend to shift the end points (increasing the pulsewidth gap) or create a single channel that outputs 4 separate pulsewidths?
If you intended the second it hasn't worked for me I get the first and therefore do not get a four mode switch.
Any ideas?
Not really... What you are trying to do is make the pulsewidth gap bigger, right?
