What's the model of that SteppIR? It's time to do our own wind loading model, I think. Do we have good info (is Doug answering e-mail?) on the mast and rotor hardware? While I know it's a Grade 8 bolt, I know precious little else about what's up there.

I have a name for someone to work on that mess up there. I need to set it all up and get it down, repair wiring, find out what has failed such that it wind vanes, and then we need to decide what to do. As far as I have been able to determine, nothing up there has a federal property ID, so we can deal with it without a lot of paperwork. If the shear bolt has failed, we need to determine why it keeps happening (this would be the second such failure); if it's a wind load issue, we need to decide what to get to replace the SteppIR. If the rotor has failed, it needs repairing and we have to face getting an antenna with less wind load. I suspect we need less wind load no matter what. I wish we could find a damping unit to reduce the shock loads, but I have no idea what to use or if such things exist that fit our needs.


If we get another antenna, how does that process work? Who decides? How is it purchased? In fact, what entity actually buys it? I'm the WX5NWC trustee, so I guess I'm going to be somehow involved...

Likewise, I can spend a few hours; busy time with the holidays and all that entails on top of everything else.

Yeah, noticed that the stepper lost another half element somehow.

I can try to spend a little time associated with this but I will have to also keep the spousal unit happy with me... I can operate a bit. One would hope NWC would be active.

That would require someone to have entered it.  :-)

Gary, WB5ULK, wants to operate.  I expect to have a computer suitable
for electronic logging available in time (I won't be here tomorrow or
Thursday but will have it Friday).  The Steppir is OOS, as you may
know, but we have the vertical+tuner available.  I have a D-STAR radio
available as well assuming there is to be D-STAR operation.
