I \nthink some of the newer receivers can compensate for this, but I'm not sure.\n\nIt's been about 14 years since I last worked in the GPS industry, and \nI'm a bit rusty on all the new stuff!\n\n73, Jim KQ6EA\n\nOn 02/02/2012 04:57 PM, George and Cheryl Abbott wrote:\n> I'm not sure about GPS,but I have noticed that the clock on our cable \n> box is off by up to 4 seconds at times.Customer service was not aware \n> or concerned when I let them know.\n>\n> -----Original Message----- From: Vince Fiscus, KB7ADL\n> Sent: Thursday, February 02, 2012 10:28 AM\n> To: [email protected]\n> Subject: [amsat-bb] GPS Time observation\n>\n>\n> I have an old GPS unit, a Magellan explorist 210.
