Default Crystals for Airtronics?

I know JR crystals will work in an Airtronics radio, but what other brands will? Anybody know?

And the Performance Devices crystals are reasonably priced, and they work great. Used a few in my MX-3 with no issues whatsoever. I paid like $10/set (Tx+Rx) at my LHS

It depends on the frequency.

27mhz fm (all crystals work)
75mhz fm (depends on whether it is a positive or negative shift radio)

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.
