[time-nuts] Re: Synergy replacement receiver boards for Z3801A

Lon
Really appreciate your insights.
Can you share the installation procedure?
Was it just drop in, no setting the module up. Or perhaps Synergy has some
detailed settings?
Like you, I have z3801s and one day the modules are going to fail.
What is the approximate cost please?
Thanks for sharing.
