KO Propo KR302 F interferences
 

I'm having some problems using my Ko Propo KR302F micro receiver with a personal transponder. Every time I plug the personal transponder in, it gives interferences. I tried installing the personal transponder on different locations, but nothing seems to help. With the receiver of the Mars R, it seems to work glitchfree, but I would like to use the smaller receiver. Any ideas on how to solve these glitches?

Thx
