Brad, I sent you a private msg about your radio. Will put the results online later. Philippe

After a quick look, JR products look (externally) similar to Graupner.
The buddybox site [link]http://users.belgacom.net/TX2TX[/link] decribes Graupner transmitter student connectors in great details.
The graupner site [link]http://www.graupner.de[/link] has an english version and will show the
Graupner names for the models.
Hope this helps. Anyway tell me your JR xmtr model and if a student plug is available.
As I told you, Graupner mc-20 and mx-22 have already been connected for FMS, without additional (expensive?) Graupner plug,
and connection to many other models should be possible.
Philippe
