Need to verify there really is 12 going down coax. Menu item is set correctly. Not using any external amp. I’ll get back when I verify the coax voltage

Another question - do you have a brick amplifier inline? If yes, make sure the amp passes DC. Some - like Teletec - are DC blocked.

Have you verified that the 847 is actually sending the 12v up the coax?
If
so, then I'd look for an open RF choke in the pre-amp.

power down coax with ft847. This does not seem to work and I’m
wondering if
I need to make some sort of internal change to the preamp. The manual suggests I can power it through the coax. Any thoughts?
