We filmed this test up on the Wirral Peninsula in North West UK and performed the test across the River Dee to Holywell in North Wales…a distance of almost precisely 10km.
The T80 Extreme devices were running on fully charged Ni-MH batteries and are unmodified in anyway so were outputting 0.5 watts which is the maximum allowed unlicensed for this type of radio under UK law.
Thanks for watching and please let us know if you enjoyed the video.
