So all negative shift crystals work on negative shift radios, no matter the brand, and same for positive shift?
Some of the stuff gets confusing, especially when you get into universal crystal-controlled receivers, like the Hitec HFS-03MM and HIS-03MK. Hell, throw the DCX into the mix as well.
I have a Multiplex Profi 707 synth, but man, the MPC crystals are kinda' expensive, if you want to use a crystal-controlled Rx.
