Re: [time-nuts] indoor GPS test.

Hi, I bought a Garmin GPS 17, which also has PPS, for about $100 from an online dealer. This model runs off 8 to 40 volts, so runs off 12V quite well, has 5V logic PPS, as well as connections for serial input to a PC. Neville Michie On 25/01/2008, at 6:16 PM, Hal Murray wrote: > >> The GPS

Most of the runs will be indoors, the "Harshest Environment" will be dealing with the occasional mice! I'm thinking about running RG-6 Quad shield cable. On second thought, my "Harshest Environment" will probably be the "technician" that will be attempting to trouble shoot a non-existent problem!

No colour codes that I'm aware of. I'm interested to know how long your cable runs are going to be and the environment you are in (benign, harsh...). From past experience if very long distances in high noise environments you may want to think about using fibre optic links. Also, you need to lo

Steve intended to post this to the list but it came directly to me instead. As he doesnt have a copy of it I am posting it for him. Bruce Hello, (as requested..) Here is the Euler derivation. For simplicity I will use "B" for the first part then expand it. I made a boo-boo in my earlier email.

Is there any standardized color coding for running "timing" cables? I have an upcoming project, and will be running some long cables for 1PPS, 5/10 MHz, and IRIG-B, and was wondering if there's any standardized colors that people have been using, or if there's any recommendations... Thanks!! Raim
