[amsat-bb] Mirage T-Injector Problem

I've finally diagnosed the problem with my new ARR preamp. I really thought
it was the preamp until I got it on the bench and found that when I power
the ARR preamp via the coax I see the under load the T-injector's DC output
drops about 2.5 volts to about 11.15vdc. How can this be? Any suggestions
on how to modify the T-injector so this doesn't happen? It strange as I've
used several different Mirage injectors with their preamps and an Icom
preamp with no problems but neither Mirage injector I own works with the
ARR preamp.
