Ed,

I don't have any first-hand knowledge with the Oncore, but with 'other'
GPSDO's that haven't been turned on for some time (weeks/months or longer)
or almost always from a significant change in (antenna) location, there
maybe a significant time lag before the (a) oscillator gets up to
temperature/frequency and (b) for the internal search algorithm to figure
out where any satellites are as the almanac in memory has either been dumped
or the previous old QTH is used, hence all the satellite coordinates are
incorrect.

Try turning the kit off, wait 30 to 60 mins, power up again and see of it
acquires 'lock' somewhat quicker.
