JR 622 upgrade
It most likely will, It is made for JR expansion ports, however, the JR 622 is an older radio, and I am unable to find photos of the expansion bay.
The Frsky module such as the DJT will work with most radios with a PWM output and the JR standard expansion bay.
Let me know if that helps to answer your questions!
