[Skimmertalk] WZ7I Skimmer offline -- electrical storm damage

[W3OA]

  Hi Wes -

Sorry to hear about your damage.  Please give us a report when you find 
out what was damaged and if it could be repaired.

I'm using the protection circuit Phil describes in the FAQs 
(http://www.srl-llc.com/qs1r_latest/Documents/Schematics/qs1r_rxprot.pdf)  
I think Pete also wrote an article describing a similar circuit in NCJ a 
while back.

I wonder if anyone has ever experienced damage to a QS1R when protected 
by such a device?
