Default CH721 control head on Orion mobile

I know Iím probably grasping at straws here but is it at all possible to use a CH721 control head on an Orion mobile? Iím wondering if there is a way to modify a can cable to patch it into the Orion control cable or if the DB25 on the rear of the 721 could be used possibly. I have an Orion uhf mobile that has a bad control head and have a 721 head laying around thought I would check on the possibility of using it. Havenít come up with anything one way or the other on google search. Thanks in advance!

I would say no. As they are 2 completely different control heads and ways of communicating with the radios.

That’s what I was figuring but thought there would be no harm in asking not like Orion control heads are that expensive just thought hey I got this one maybe I could get them to communicate. Thanks for the reply and have a merry Christmas!

Maybe a bit(?) overstated...

CH-721 Control Head (& SP-721 remote) = Pentium quad core running Windows-XP

Orion/J725m/M7100 head = Commodore VIC-20


Any questions?
