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

I have an older orange case SSB2000 model preamp. I used to use it for EME but replaced it and now want to use it in another installation for satellites. I do not however want to power it separately and want to send 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?
