The reason it caught me out, is that I had changed to version 3.30 (where it also delays NMEA) on the 27th Sep 2010, and it took a couple of months to manifest as a problem. It was the rising of the sap in my trees combined with windy weather - which pushed the NMEA into the next second for my

I just bought a Nuvi 265WT and after I entered my home address, it says home is .2 miles away. I know this is a map error, but the map comes from Garmin. To me, this is unacceptable. I will complain, in vain, I am sure, to Garmin. Sorry to be off topic but when I saw Garmin, I couldn't resist

Carefully drill small hole in the switch housing.  Use a hand pin vise,  you don't want the drill to damage the switch works.  Orient the drill pointing up so shavings don't fall into the switch.  Then spray your favorite contact clean/lube into the hole.  Works well for most switch problems

Fellow time-nuts, Just for fun I have been looking at the mains as a time-reference. I've used an OSA 8600 as reference and divided down to PPS by a TADD-2. While not absolute time reference, it is way quieter than the mains so I think it is good enough to have some fun at least. Just to

I think you would mean an automatic correction according to the measured position, and not based on a setup parameter (offset to UTC). It should be noted that time zones are not necessarily defined by meridians, and in general they do not. To do automatic corrections you should have mapped
