It sounds like you covered all of your bases, especially since you plugged the ePMP radio in where the 450i was and it didn't work. So some of the ones below don't seem to apply:
What voltage are you running the injector at? How much cable length are you running? The ePMP radios reallly are picky about 24V and long cable runs, especially when it's cold out. This is a gigabit syncinjector, right? If so, I won't ask you if you changed any jumpers in the units. I do have one very odd request: If these are shielded cables running up the tower, can you somehow break the shield on the bottom end? A short unshielded pigtail to a keystone jack often works. If you have a surge protector at the bottom, try inserting this either between the injector and the surge, and alternatively between the surge and the cable up the tower. I've had 1-2 reports that reterminating the cables with unshielded ends at the bottom causes otherwise unsyncable ePMP radios to suddenly start receiving sync. -forrest On Mon, Feb 20, 2017 at 9:14 PM, Brandon Yuchasz <[email protected]> wrote: > So to update this previous post.
