It definitely is a positive shift receiver so yes indeed it will work with your positive shift transmitter.

Now understand that you must use a Hitec dual conversion crystal in the receiver that is the same frequency as your transmitter.

All most all hitec receivers that were not shift selectable types were either positive shift or negative shift. The purchaser selected the modulation shift type he needed. Your JR requires you to use any FM (PPM) receiver that is positive shift.
