Next priorities / coming soon:
TVMAP with common layout and functionality, updated data and DVB-T stations Google has still not included all sites though txt-sitemaps have been submitted. maybe xml-sitemaps could help? better layout for power and height diagrams grid for network maps region name in headers of network frequencies / maps French language target ciraf-areas for sw with translation tropical band stations and transmitter sites for SW

Known bugs:
SW frequency graph: low dB values at s/on, background colors for transmitter names, location overwrites accellerate detailled maps height cross section still with some bugs coverage circles end before the edge of the map empty haat appearing in network listings (without receiver location)- height and haat would be more useful swscan: beam direction bugs?
