Since a bunch of the switches on my 1992 are bad, I was going to buy another to use for donor switches. However, I would also consider getting a 1990, 1995, or 1996 if those had more features. Anybody know the real differences from the 1992 to those other models? Thanks, Matt

[time-nuts] How best to compute local time from GPS

O Time Nuts, I am working feverishly on the software for my new scope clock. This is a circuit board that drives a 3 oscilloscope tube with a rather good-looking display of numbers and letters, driven by an HC908 MPU and a hardware circle-drawing engine. The basic gizmo is shown here:

1 Is there a reasonable way to determine the local time zone from the GPS sentences? None that I know of. But given that you have GPS you probably know where you are. If you had a map of the globe with the time zone boundaries drawn on it, you should be able to figure out which zone you

Hi Folks I know that we talked about extending antenna cables not that long ago, but I don't think that we resolved *how* the cables should be joined other than that the type of soldered splice I was proposing was not a good thing. I've decided to run the indoor sections on RG6, since that's
