You need both the feed-through capacitors and the BNXs (or similar) - the filtering MUST be inside the box. The copper of the FR4 should be grounded. And, yes, its a sort of Faraday cage. > If my efforts fail, either syncing with the HV off or going with the > idea of an off-board receiver module are decent fallbacks.

Very good & cheap devices. Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
