    Bill,

    You state:

    "As for my RCC that was the subject of so much supposition after Alex and
    I observed together, it has been put through every torture test I can
    devise without destroying it, is viewed approximately 40 times daily,
    and has never so much as hiccuped. It is spot on after its 2 AM EDT
    reset. My only problem with it is a 0.9 second drift (slow) over the 24
    hours between resets. Voluntary standards would have it within
    plus/minus 0.5 seconds of UTC at any time. Fortunately the drift rate
    is constant, so easy to mentally adjust to UT1--until the June 30 leap
    second ;-)"


    I too noticed about a 1 second drift on my Seiko radio control clock between resets. The clock can be reset manually with the press of a button which should knock out drift but I haven't verified that. My camera clocks also have a large drift which means setting and checking before every series of CN images.

    As for your RCC testing I would try transmitting a VHF handheld radio at 5 watts right next to the RCC to see what happens. I will try this also. Ham radio transmitters may have influence also. Even gas engine sparking can disrupt or alter radio signals. Lately I've noticed that my shortwave gets knocked out on 10 Khz when my laptop charger is plugged in. I use the RCC but always double check the minutes with another non RCC watch.
