Joe sent be a receiver and I have finally verified it works sorta. It
took a couple of weeks before it found WWVB, but it did. I connected it
to deacon for test. When it first came up ntpq reported it as working,
but after a couple of minutes the driver aparently went into a loops and
stayed there. At least ntpq timed out for repeated pe queries. I left it
commented out to aviiod posssible gattery exhaust. I need a little help
here, as I cannot clearly see what I am doing.
