Are you sure it has a T/R relay inside of it? Perhaps it's a repeater amplifier 
with no T/R switching. If it does indeed have a relay, the relay must be 
defective. Does the receiver work when the amplifier is in line and not

  Hi guys

  I have a TE SYSTEMS 1412G that has a problem where with the amp in circuit
  and turned off  ie by passed there is a high SWR and almost  no power
  out the other side.

  When the amp is turned on in operate mode it works fine low RF input
  good swr
  and high RF output.

  I opened it up is find what looks like a sealed relay thinking bad or dirty
  relay contacts.

  Has anyone had this issue ? I have looked on the web for TE SYSTEMS
  with no luck.   As I need a manual as well and circuit diagram.

  Any advice is welcome.
