Keyhole Radio™ for Android builds upon years of positive feedback from the original Android RF planning app 'RFSignal'. It puts the power of Keyhole Radio onto an Android device and allows you to share overlays, templates, clutter and settings between the Android app and the desktop/Google earth version so you will be able to recall all your work whatever interface you choose. It has extra antenna and environmental settings to enhance planning to the same standards of accuracy as the desktop interfaces.

Free download (CloudRF account required)

Keyhole Radio is available for free in the Google Play app store. New users will be credited 100 credits for use via any CloudRF interface once registered.

Powered by dedicated 64-bit servers and supported with NASA terrain data from cloudrf.com accurate to 90m. You can search and use templates and ground obstacles (clutter) created within the web interface and use it later on your phone or save a template from your phone whilst in the field, and find it in the web interface when back at the office. All calculations are saved in your own private online archive and can be recovered as KMZ overlays for viewing offline with Google earth.

..Excellent Works like a champ. Pinpointed two poor radio coverage areas that were proven to be bad with real on-site radio testing - William
Super! The program works on all 100%! After you have entered all the correct information about the antenna on my APRS Gate "RW3DKE-2" real coverage coincides completely! Thanks to the authors for a useful program! - A Google user
