[TowerTalk] Tuner SWR won't stay down

Has same behavior on dummy load?

Try getting rid of all coax switches, surge suppressors, anything in the RF 
path to antenna, then swap out jumper cables & connectors.  I am thinking 
cable/connector issues in the RF path. It's possible the issues are not even 
located very near the tuner.

A puzzler for sure.

Hi Bob

No, it matches the antenna just fine.  SWR goes to zero.  Then it starts
to creep up after a few seconds.  Then I can re-tune it back to zero
again, but doesn't stay there.  Thanks and 73
