The map to the right is the best  representation of the final 13cm coverage area to date. To view the map in close up click on the map shown. However the map prediction does not show all the "RF problems" caused by many Wireless Area Networks (WANs), microwave ovens and other forms of interference that cannot be accounted for by the prediction software. 3cm coverage should be fairly similar. We will post a more accurate map as more testing is carried out and more reports are received.

GB3BH 13cm, 3cm (10GHz), 70cm (437MHz) coverage
