The main consideration is relay speed. If the relay is
switching or contacts still bouncing while RF is coming out,
you are in trouble!
I'm not sure what the relay timing is now in the Orion.

Other than that almost any standard ~10 ampere relay would
work. I'd try to pick a small relay with large contacts, and
a relay with large movable contact wires or a direct
armature connection. Something like a KA or KU/KUP  series
P&B would work.
