I posted the question on Groundspeak forums on whether there is any issue with the Sat Signals between morning and afternoons and one of the responses that I said the following:
Satellite configuration is the most likely cause. The satellites move in orbits of almost 12 hours. Where they are has a direct impact on signal strength.So it appears there could be some influence in positioning.
Well, Thursday was my last ride for awhile, because Thursday afternoon I had a little outpatient surgery that will keep me out of the saddle for a couple of weeks. Needed to have something fixed to prevent any more future college tuition payments. I figure three kids are enough.
The procedure wasn't too bad. A little sharp here and there even with the local. Post surgery recovery includes alot of icing, keeping off my feet for a couple of days and percosets. Still, it feels like I got kicked in the you know where, twice, when the percoset wears off.
Hope that wasn't too information for you.
