Mapping it Part 2.

Now if you need to know how far with my maps under google maps all you do is draw a line? See below:

The blue line from Llantrisant to the Sphinx show how the crow flies, it’s not that I’ve made contact from these two points but I visited both and they are well known land marks in both areas. If you click on the line a little buble will pop-up with the distance (2308.22 mi).
So if you’re a budding Ham and had a few contacts and someone asks “how far can you get?” you can now pop on google maps and give them a number. By the way google ID’s are a good idea you can get gmail, mymaps and even a shiny blog like this one.

Mapping it

When I started playing with radio one of the first thing people ask is how far can you get?
This was most time answered with a shrug. As to work it out when I started normally needed finding a map(large paper thing) a ruler, paper and much scribbling. Now by the magic of Internet and google maps you can show people on your blog.
see link http://maps.google.com/maps/ms?hl=en&ie=UTF8&msa=0&ll=51.551672,-3.37409&spn=0.036132,0.111151&t=h&z=14&msid=212386886707637984966.00049a09dc780d7dae5c8
 or embed right into page.

but these are what are known as static maps. They can be explored by you the user but they are a static snapshot of MyMaps on google maps and there is a limited views per day.
They are cool enough for showing your readers where something is or how big it is.
if you want to do realy clever stuff you need to play with the google maps API. when I've worked that out I'll let you know.

but if you want to see what others are doing have a look at http://googlemapsmania.blogspot.com/

PFK out.

Joy of Radio Control

I bought two little Radio control Cars for Christmas with the hope of a race or two.
but when I opened them and got them set up?
Oh joy they are on the same frequency 27.145Mhz why?
There are 6 different Channel I think but some say 30?
