[time-nuts] Re: Query about List and about 10 MHz Distro

[Andy Talbot]

When I asked about this on another Group a while back, I was told the phase
noise made it an undesirable solution.

Although I never tried it, I would imaging balanced shielded twisted pair
would be a better way to go.   Immune from ground loop problems than can
beset coax distribution and a whole raft of ICs support the medium, from
RS422 to CAN bus drivers and receivers.
