RE: AFP deluxe- recognizes USB, but no interface on jr 8103
The reason that it's stereo is that it will be universal for Airtronics and JR.
BUT JR did change the tolerances on their DSC ports which then changed the plug. Nobody's going to blame JR for anything.
However since his radio is an older version of JR, then it's not going to be the plug.
Also take your module out .... do you have another JR radio you can try?
