[Icom] IC751 owners - Help please!

Fri, 27 Dec 2002 16:30:19 -0000

Hi Chris

Well first of all you will need the UX14 interface board building into the
rig, that will give you a CI/V port where you could then connect your CI/V
interface.

Unfortunately the UX14 is no longer in production, and whilst one of the
guys in the group did find some a while ago, I doubt there are many about
:-(.

Sorry to pass such sad news. Although someone out there may have a UX14
interface for sale.

Best Regards,

Dave G3VFP
