Anyone know if you can use the RadioPopper JrX StudioRx with Yongnuo YN-560 using PC Sync cord of course since the RPCube wont work (not canon/nikon). I know i cant adjust the power level from JrX Tx or w/ PX Tx. I'm not too concern on that if Im gonna use Yongnuo. Just wanted to get another flash for manual use only.. w/ no adjustment needed at all.
