I have an existing 4gb stick in my slug which is beginning to regularly fail. Can I use a 8 gb stick as replacement? Can't seem to locate 4gb sticks any more. Do I have to format the 8gb stick any differently and do I still use the 4gb stick image (meteohub)? I ask this because my 1st few attempts at doing so have failed using winrar and roadkil. After writing the image and inserting the stick in the slug, I get proper startup lights but then no beeps and just two steady green lights.
Any help is much appreciated. Long term solution is to switch to meteobridge after my tp-link router arrives as I just upload to wunderground and cwop. ( wish I didn't have to pay another two license fees for my two wx stations in Phoenix and Canada

)
Thanks for your support,
