There are two methods of wireless connection.
1. Bind the external module to the student transmitter and the internal module to the receiver in your model.
2. Bind the internal module to the student transmitter and the external module to the receiver.
I have personally used the second option with great success. However, the external module you choose and receiver you are binding to will possibly have an impact.
I swear by FRsky, so use an XJT external module. It has the option to bind to other protocols but I prefer to use ACCST, this allows me to use a variety of FRsky receivers and Radiomaster receivers using D8.
As for the the buddy lead, its a specific to the Radiomaster a standard off the shelf jack plug has different dimensions, as my good mate keeps reminding me.

"The issue I had with mine was the little metal tabs on the female jack inside the radio weren't pressed in enough to make solid contact with the male end of the plug.
I had huge issues with the trainer cable until I talked to Radiomaster support. They suggested I open the case, and gently push the metal tabs in a little bit further so they made more solid contact. Solved all my issues. So this is another thing you can try if you're having trainer cable issues."

That is common with all 3.5 mm jacks be it in a radio we use to fly, mp3 players, or headphone jacks on anything that uses them. They have very low life span repetitive connection counts because they are so small and that pole used for main contact is so thin and not real good spring steel like the older 1/4 inch jacks used in musical instruments. sometimes they get plugged in enough the plating on the contact wears off and they corrode as well IF the unit last that long without the issue you had.
Hope this helps, if you need I can post the exact set-up I used
