But before you make the new connections, use Scotch-Brite or a steel wire brush to burnish the oxide off the aluminum and IMMEDIATELY coat it with AlumiNOx or whatever the equivalent aluminum oxidati

One small correction - steel wool is not recommended because it will leave small particles of the steel wool on the aluminum, and embedded in it. Wire brush or Scotchbrite are the best choices. 73, D

Not to keep dragging this out forever, but, used to be, the greases came in petroleum-based and synthetic-based. For obvious reasons, the synthetics are better - if there is a choice, select them. Al

Date: Thu, 12 Mar 2009 17:08:25 -0500
On the Orion I, and I assume it's the same on the II, the "Tuned" indicator only stays on if the tuner can successfully bring the SWR below about 2:1. If it cannot, the "tuned" line is turned off. 73

You said: "no matter what the SWR is" . . . If the SWR is 4:1, the tuner will not have found a tuned condition, and the "tuned" indicator will not go on, and the tuner will be disengaged. I don't rec

That is not how my Orion I works - if it cannot find an acceptable SWR (I don't know what the value is set for) it will end it's tuning sequence and the "tuned" indication will NOT be turned on. I wi
