Stop-work order was issued because of assembly problems
(bubbles in the adhesives holding the Omnetics connectors)
Proposal to get 3 sets of bare cables and assemble at a company of our choice (TBD).
(This was in my original plan but apparently was omitted by the green eyeshade people.)
Need answers from coupons before assessing further steps.
If ok, Robert requested delivery of the “bad cables” for test of the integrity in vacuum (thermal vac?)
