    keyword=L-HRS RT module swapped out. put in spare

    To effect a more permanent fix to the problem of flakey connector
    on the RT module, I swapped it out on the L-HRS. I will get the
    old one fixed by the electronics group.

    I checked the delay overhead -- it's 120 nsec. It's normal/good.
    This means if there is no RT relative to L1A the timing jumps
    by 120 nsec; you would see this in VDCs as data to the right of
    the normal TDC spectrum if there was an associated VDC hit.
