grlevel3 Questions

[MG Jennings]

I have two quick questions which I am unable to find in the tutorials....any assistance is greatly appreciated

1. When the ring range is on, how many miles are between rings?

2. When I first turn the program on, it takes several minutes to load the radar loop of 10 volumes. Is this normal or am I missing a short cut which will load the data quicker? In StormLab, it only takes a matter of seconds.

Thanks in advance for the assistance.

1. 25 miles
2. I believe its normal

1. The distance between concentric range rings is 25 nm. If you ever forget that, you can derive it yourself using the range information in the little box below the lower right corner of the radar display. Like in my response to your previous question, the range given there is the distance from whatever is your active marker. If you have not selected an alternate home or marker by right-clicking, then the default location is at the radar site you are currently polling from. To see how that changes, try selecting different home or marker locations while the range rings are turned on. You'll notice the center of the rings jump to the location of the marker when you change it.

2. The length of time it takes to load data depends on at least 4 things that I can think of:
a. Your internet connection
b. How many products you are trying to load (although the products are supposed to load and appear individually, but they are all trying to load at the same time)
c. The radar site (some sites may be experiencing technical difficulties and you may get longer load times for them)
d. The server you are polling from (is it slow/down?)
If none of those give you an answer, try changing the initial site when you open the program (the default is KFFC, try something else by going to Site -> Settings... -> "Startup Site:" box. See if that changes things.

My radar loops have never loaded 10 volumes on startup. It simply caches the volumes as they are downloaded for each individual radar site. It has been this way on every computer I have ever had GR3 installed on (4 different machines now). So in essence, assuming 5 minute scans, it takes 50 minutes to cache 10 volumes. If it is supposed to work differently I would love to know so I can figure out why mine is broken

Did you know you can just hit the "start archiver" icon (the white pages) in the menu and it will back build a loop for you? Granted you have to do it for each product to get the full loop, but it's a great way to see the past however many scans at startup.

Somehow it has completely escaped me. And to think I never thought it awkward that I was getting no looping on startup, just figured this was normal program behavior. We all have our moments, thanks Jeff.

Thanks Jeff....just what I was looking for regarding the loop!.....as for the distance, I simply must be having many senior moments in a row because I can't figure out that feature to save my life. Likewise, it displays feet and I'm not crazy about that. StormLab has a very simple way to get distance in miles so I'll probably continue to use that feature.

Remember that there's a difference between a nautical mile and a statute mile, the latter being the one we landlubbers normally deal with. A nautical mile is somewhat larger, and the difference adds up. Twenty-five nm equates to 28.8 sm, or 29 miles, if you allow for a little slop. So if you're thinking in land miles, which most of us do, then each ring actually represents a distance of just about 29 miles, not 25.

Here's a link to a quick conversion tool that you might appreciate.

Thanks everyone for the assistance.

Need to also remember that the more "tabs" you have open in GR3, the longer it will take to download the data. Only open the default (BR 0.5 I believe) and open otehrs as needed. That will dramatically cut down the download time.
