I am still interested in what you do with your XP7202, but here is what I did last night and today.
I received a JR module in the mail yesterday. After opening it up, I discovered that it would not be so easy to remove it from the case - seems to be "glued in". So I decided to mount it on the outside of the XP7202 – see photo. Obviously, this is not a permanent way to install the FrSky module. I just wanted to get out and see if in fact it worked - therefore telling me that my DIY module had a problem.
I had removed the DIY module, but cut the wires so that I still had the diode on the PPM wire. I then soldered some more wire to each of the three wires (PPM, +, and -) with pins on each end. I then routed the wires out the hole that I had used to get to the bind button with the DIY previously. I then inserted each of these pins into the appropriate receptacle of the module. I used a space and some velcro to attach the module to the back of the transmitter.
I went out today and flew my Slow Stick - the one that had previously had some uncommanded elevator inputs after installing the diode and crashed. After fixing the bent fuselage as best as I could, I bound the new RF to that receiver and went out to fly. I did a range check with the reduces RF output and got 64 paces (yards) and felt good about that – that was much more than what I had with the DIY module after installing the diode. It flew fine and I got much more altitude and distance away than ever before.
Therefore, my conclusion is that I had a bad DIY module. I am hoping that FrSky will replace it with a new DIY module that works. That way I can have a cleaner and permanent installation inside my XP702.
Please let me know all that you find out about your XP7202 and hopefully you will share some pictures of your installation.
Thanks in advance.
