As I discovered during the peak of the ETA-Aquarids with contacts made with VK3's and copied VK5's Adrian VK4OX is the expert with this . There is which is a great help just enter your callsign and your locator the help section is a great read . Change west to be on left side of great circle and click antenna azimuth and your all set what it doe's have is a link to the international meteor organization which has a meteor shower calendar.

Unlocking JTMS and DIANA modes in ver 9.3 Wsjt

Unlocking the hide file extension option in windows I will use 7 as the walk through.

First go control panel  then change the view to small icons

like so

Select folder options it should be in the first column 4th or 5th down

Now untick the hide extensions for known files

Open notepad and create a file called experimental and save it do not put anything in the file
just create one and save it as experimental

Oh and save in the WSJT directory you will find this under program files
if you are using windows 7 64 bit it will be in program files(x86)

You will see that experimental has .txt extension now
just right click on the experimental file and select rename
and just delete the .txt off the end

Windows have a warning just click yes it won't break anything

No open WSJT click on modes JTMS and Diana will be on the bottom of the menu enjoy
