Questions about Radar loops:
-
Q. Radar Loops have never worked on this web
browser.

-
Where you see web links like '128km - loop', make sure you click on the
word 'LOOP'. (Clicking on '128km' will only show the latest static
image.)
-
Loops need JavaScript to work.
Some web browsers have scripts turned off. Others may not be able
handle radar loops at all.
See Radar Loop Diagnostics
to check this browser.

Q. My radar loops used to work, but they have
stopped working now.
-
If your radar loops used to work but do not work now, it is probably a
problem on your PC. Check:
-
is your disk full ? (You need to have several Mb spare space)
-
is there a virus in this PC ?,
-
is there a problem with the PC-firewall ?.
Perhaps use the
Radar Loop Diagnostics
to check this browser.
A rare problem might be that you have an old or incorrect bookmark.
Perhaps revisit the Radar Home Page, select
the radar you want, and then set up a fresh bookmark.
Another rare problem might be that if you now only see small broken
images instead of radar images, then maybe your ISP (Internet Service
Provider) has blocked radar images. Perhaps contact your ISP to see if
they can run the radar loops, and whether they see a problem or not.
-
Q. The loop counter counts from 1-4, but the
images do not change.
-
Look at the time-stamp line at the bottom of the radar images. The times
should be increasing by 10 minutes each image. Sometimes when there is no
rain, the images all look identical and the only thing changing is the
time stamp.
-
Q. There are only 1 or 2 or 3 images in my loop
when there should be 4.
-
This usually happens with part-time radars after a 'windfinding' session when the radar has been down
for one and a half hours, and has only just come back up. Only 1 or 2 or 3
new images are available. It takes a full 40 minutes before all 4 images
are available.
-
Q. I see Blank or Partial or Broken images during
loops.
-
Q. Why is my PC is continually downloading
data during loops ?
-
Q. Why is the mouse pointer continually
flashing an hour-glass during loops ?
-
When loops are running normally, there should be no further downloading
from the internet - the images should all be in the PC cache storage. If
your PC seems to be continually downloading new images, or the loop shows
partial or blank images, or the hour-glass is flashing, then your web
browser cache settings may be wrong, and the browser is accidently
rechecking the internet every time around the loop.
See Browser Settings to check your
cache settings.
-
Q. What are the download volumes if I leave my PC
on radar loops all day ?
-
One new 20Kb-30Kb radar image comes down every 10 minutes. This means
120Kb-180Kb per hour, or approx 1 Mb every 6-8 hours.
-
Q. My radar images seem to be old.
-
If your radar images are obviously very old (e.g. over a day old) and do
not change after you press the Refresh/Reload button, then you may have a
Web cache problem.
-
Q. The date-time on the radar image is plainly wrong
(e.g. year 2000, 2010, etc)
-
Occasionally radar machines lose track of the correct time of day, and
send in images with bad dates like year 1990 or year 2010 etc. We try to
reset radars to the correct dates and times as soon as we can, but some bad
date/time stamped images may be displayed for a little while.
