On occasion (twice so far) my GPS receiver, a Magellan Sportrak, gets wrong readings. For example, it might say that I moved 12 miles in 2 minutes, while I'm actually walking in the city. (The position is then wrong for several hours -- even if I power-cycle the device -- though the velocity reading may be correct sooner.)
This sort of condition hasn't lasted for more than a few hours. I always thought that it was because of the satellites being resynchronized, though that's a rather odd proposition for a system with the sort of requirements that GPS has. But now I hear that it could have been the weather instead. ...
And what's this business with a secret word for the subject? Am I just supposed to guess?

[TELECOM Digest Editor's Note: No, you are not supposed to guess regards the secret word ... the secret word is the first word in this response. What am I supposed to do, go through several hundred spam/scam messages daily in the hopes I will can guess at the one or two good valid messages every day? I had hoped -- sincerely hoped -- several months ago to be able to quit having to go through the mountains of spam each day and only refer to the files which had the secret word in them? I refuse to keep going through the rationale and reason for this request. _Regular readers_ are tired of seeing it over and over. I am not going to continue being the straight man in this comedy routine. Most days, spam constitutes a minimum of 95 percent of the telecom mailbox; more often than not, 98-99 percent.
