[Skimmertalk] WZ7I Skimmer offline -- electrical storm damage

[Pete Smith N4ZR]

Ouch - sorry to hear that, Wes.  The storm largely missed us, but I had 
my antenna disconnected anyway.

Something I found out the hard way - I lost two RS-232 boards in my K3 
before I learned the importance of having computer chassis and radio 
chassis grounded to a common point.  I am taking some steps, both to 
improve the RF shielding and the grounding of my QS1R.  I'm adding a 
star washer and nut to the RF IN jack (after scraping away the powder 
coating), and I will ground the case through one of the rear corner screws.

If anyone has gone this route already, do you know the size and thread 
pitch of the BNC jack that Phil uses?  My caliper says 0.490 inches, so 
I suppose it is 1/2 by ?  Maybe 1/2-32?
